Usually tho, any calls I made on 10, were to get hold of a specific someone, and so if I got no responce by voice, I'd try CW a while. Sence that worked...I'd always get em using CW ( then we'd switch to SSB or if air was clogged tight we'd skinny-up and stay on CW), it became a matter-of-course to start with CW, and optionally switch to SSB. This was also good to use ( CW ) when the air is busy, and yer trying to get hold of someone who's waiting for you on XXX freq and there's one of those 10-4 things going on... so, by moving up 2-2.5kc, and run CW, you don't bother the 10-4 people, yet who's waiting for you, hears the hi-pitch CW way up there and can dial up to reply (then we go hunt for a new freq) As far as the 10-4 people go, they think it is 'someone throwing carriers' and they ignor it. -- Randy KA1UNW If you get a shock while servicing your equipment, "Works for me!" randy@192.153.4.200 DON'T JUMP! -Peter Keyes You might break an expensive tube!

Grabowski) To: QRP@Think.COM Subject: 10 Meter QRP SSB Reply-To: al838@cleveland.Freenet.Edu (Eric J. Grabowski) A couple of years ago, I bought a Radio Shack TRC-453 ssb CB radio and converted it to 10 meters. I got it new, on sale for $120.00. The conversion is very easy and consists of removing a capacitor and adding an oscillator. I built the oscillator on a scrap of pc board about the size of a postage stamp so it fits behind the channel selector switch. The oscillator uses a crystal and two MPF102 fets, one as the oscillator and the other as a follower. I have made several contacts including W6, W7, VE5, VE6, and VE7 with reports between 5 x 8 and 5 x 10/9 using this radio and a Mosley TA-33 at 30 feet. Most stations commented on the excellent audio. The only disadvantage, which is a result of my conversion, is that the RIT has very limited range, i.e. about 300 Hertz. I have since designed an L/C type oscillator with a varactor diode that provides enough RIT to span the distance between channels. Although I have a breadboard version working, I have not built it on a piece of pc board to fit into the radio like the existing one. If you're looking for a qrp ssb transceiver for 10 meters, I would suggest that you consider this approach. There is not a lot of work involved, it is relatively inexpensive, and it does work. ---73, Eric -- Eric Grabowski, WA8HEB al838@cleveland.freenet.edu Chagrin Falls, Ohio From qrp-request@Think.COM Sat Nov 20 15:48:08 1993 Return-Path: (5.61/UUNET-internet-primary) id AA07246; Sat, 20 Nov 93 15:48:03 -0500 (queueing-rmail) id 154659.5412; Sat, 20 Nov 1993 15:46:59 EST id m0p0z9Y-0007L9C; Sat, 20 Nov 93 15:43 EST Message-Id: From: rich@mulvey.com Subject: QRP clubs To: qrp@Think.COM Date: Sat, 20 Nov 1993 15:43:32 -0500 (EST) X-Mailer: ELM [version 2.4 PL21] Mime-Version: 1.0 Content-Type: text/plain; charset=US-ASCII Content-Transfer-Encoding: 7bit Content-Length: 208 Well, I'm a member of the NorCal QRP club, and anxiously awaiting the Dec. issue of their magazine. :-) Can anyone tell me the addresses/dues/contacts for the other major QRP groups like ARCI, etc? - Rich From qrp-request@Think.COM Sat Nov 20 16:33:14 1993 Return-Path: id AA08077; Sat, 20 Nov 93 11:33:00 HST Date: Sat, 20 Nov 93 11:32:59 HST From: Jeff Herman To: QRP@Think.COM Subject: The 10-4 folks Message-Id: Randy, Are these 10-4 people you referred to CB'ers who got lost?

I am curious if the PTT circuit of a CB radio can handle the fast keying needed in working CW. No I didn't, Jeff. Since I wanted to use the radio in the phone sub-band between 28.3 and 28.7 MHz, it didn't seem appropriate. However, I did do some snooping and it would be quite easy to key the first driver transistor. Then, all you need is a simple electronic switch to get full QSK.

Scott, see my previous comment. >Where did you get the info to do the conversion? Instinct ;-) Actually, I've been designing and building stuff for over 30 years, and to be honest, this project wasn't that challenging. In fact, I started building one Saturday morning and had my first QSO (with VE5ST, thanks Terry) at 1217 local time that same day. Of course, I did spend some time during the previous week studying the schematic and planning my attack to minimize the amount of hacking. I should mention that the reason I converted the radio was that I wanted a little 10 meter rig for the car, but didn't want to spend ~big bucks~ on one of those Uniden HR-25xx units. >Is the radio still sold in the RS catalog? The TR-453 was replaced with the TR-465 in 1992; however, the main boards are the same in both radios. The only difference is that the new one has a black front panel instead of chrome, and the ANL switch is now a slide type instead of being on the Squelch control. >How much were the parts?

I'm almost done with the one described in the Signetics databook (using 2 NE602s, some op-amps, a 4053 and a bunch of high-precision caps and resistors). The 'heart' of this is a broad-band active audio phase shifter, requiring 12 10K resistors, 6 1000pf caps and a few other resistor values. Supposedly, for best results .1% parts would be best. For the 10Ks, I got lucky. The engineering stockroom has (had :-) some 10K 0.1% resistors. The 100pf caps I got by matching from my pile of sm 5% caps - matched to 4pf according to my cap meter. The other resistors are 1% values. The rf is generated in quadrature by a 74F74 flipflop dividing down a 48MHz signal to 12MHz. I may be able to get a better looking signal if I change my 74HC14 to a 74F14 (an attempt to better square up the 48MHz signal). From scope and spectrum analyzer, the signal looks lousy. It *is* 12MHz, but has little resemblance to a square wave - more of a rounded ramp. I'll try it this way firstm and if I can find a 74F14 I'll try that too. The main reason I'm using a 12MHz if is that I have built a 9-pole crystal filter at that frequency, to add ahead of the phasing if strip if needed. Methinks it will be heavy overkill, but between the filter and the phasing I expect to get rather decent selectivity ;-) The front end will probably be a bandpass filter followed by an SBL-1, with my trusty DDS signal generator providing the LO (after some additional amplification required to drive the SBL-1 of course). With luck, I'll have a reasonably bullet-proof front end. For testing purposes I'll only build it for one band (40, 30 or 20 depending on the parts I don't have for the bp filter). I hope to have it kludged up this week, and I'll let y'all know how she flies. If she flies well, I'll try to get dork-cad to put out a postscript file and enter it here. Stay tuned for more details. 72 -- John Welch, N9JZW From qrp-request@Think.COM Mon Nov 22 09:51:12 1993 Return-Path: <01H5LYTRRLJKCOZTRQ@tntech.edu>; Mon, 22 Nov 1993 08:52:57 CST Date: Mon, 22 Nov 1993 08:52:56 -0600 (CST) From: "JEFF M.

Power output was real close to 4.8 watts max using the Kenwood compression and high boost for audio. Observations: Heard some serious QRP contesters.. they were into the high numbers, heard more on the air than I have in any other contest. Even surprised me how well QRP worked on SSB Couldn't believe how many people stopped their serious contesting to make comments about my signal, my REAL signal report and such. Easily over 65% of my contacts stopped and actually made comments. Comments varied from people insisting I was class "A" and made me repeat the "Q" about 20 times, to you are 20 over, MANY were "Great signal for Q". Think it may get people thinking about their power levels..since most people in the contest were "B" class or WAY TOO MUCH POWER. I noticed that QRP was no different on 10,15,20 as far as I could tell from me getting through as easily as anyone else. On 40 a little more power might have been nice (but then again I don't have a competitive antenna for 40 or below). 80 meters may be a case where 100 watts should be legal ***** a really good antenna makes a setup equal to using much higher power..

First off, you need to bear in mind that there's always going to be a lot of buckshot (noise from splatter) between a.m. signals and even between ssb signals. Cw operators like to be comfortable, and they also like to have something left of their sense of hearing left when they're done operating; so they'd much rather operate in a segment of any given band where a minimum of noise can be expected. Until quite recently the bottom ends of the ham bands have been their last, best hope. 72.818353007 Don Coleman, W1VOQ From qrp-request@Think.COM Mon Nov 22 10:40:16 1993 Return-Path: (5.61/UUNET-internet-primary) id AA19911; Mon, 22 Nov 93 10:40:12 -0500 (queueing-rmail) id 103805.2757; Mon, 22 Nov 1993 10:38:05 EST id AA16338; Mon, 22 Nov 93 09:14:57 EST Date: Mon, 22 Nov 93 09:14:57 EST From: epacyna@auratek.com (Edward Pacyna) Message-Id: <9311221414.AA16338@auratek.com> To: qrp@Think.COM Subject: MAVTI Receiver For Sale Built and tested receiver PCB from "Better Ears for the MAVTI-40" see QST article in October 1985 pg.14, or QRP Classics pg.140. The receiver is built on a double sided, gold plated PCB about 5"W x 3 1/2"W. It contains all the circuits of Fig. 6. The audio band pass has been opti- mized for a 600Hz center frequency. Although a 40M double tuned band pass filter is installed, this can easily be changed for the receiver to operate on any band. The PCB also includes T/R keying and antenna change over. Just add a VFO for a fully functional receiver. I recommend the NG1G premixed VFO (see QRP Quarterly) since the VFO buffer to drive the SBL-1 is on the PCB and this would allow you to build for any band. Add a transmitter and sidetone and you can build a complete transceiver around this module. One notable feature of this reciver circuit is the notch filter which works quite well.

I don't understand why it has to be this way, when other parts of the spectrum where CW is ALLOWED is not used to its' fullest. Any one in the US with General class or higher is allowed to use SSB or CW in the upper end of the bands. If you can go on with SSB any time you like why would anybody get upset if you used CW and use only use about 1/5th the bandwidth? Another reason I've been wondering about this is because I'd like to setup a sked with a friend in L.A. to practice code. It would be nice if we could meet on SSB and then switch back and forth between modes during the qso. i.e. he could send a bunch of cw, I could say (speak) "did you say .....?", etc. Would this kind of qso draw some bad remarks from other hams? 73, mont, km6wt From qrp-request@Think.COM Mon Nov 22 12:17:54 1993 Return-Path: id AA13812; Mon, 22 Nov 93 11:14:04 CST id AA12620; Mon, 22 Nov 93 11:23:53 CST Date: Mon, 22 Nov 93 11:23:53 CST From: cieslak@cgc9.eda.mke.ab.com (Brian Cieslak) Message-Id: <9311221723.AA12620@eda.mke.ab.com> To: qrp@Think.COM Subject: Re:wooden radioes..etc Let's not for get the prolific use of paper clips to connect power from the 6V lantern battery spring terminals...or was that to power up my first computer??

I guess the logic of this escapes me. Maybe this is a gentleman's agreement if terribly outdated and needs to be redefined. How do we go about doing that? If we show up in the SSB portion of the band, they can't retiliate legally by coming down into the CW sub-band. I can understand about some portions left open for calling frequencies, dx openings, nets, long established skeds.

I'd push it back in the board, and it would over-conduct again.... It took me 3 trips down town, before the guy asked what I was doing...

That lets us ID in case our mic burns out or the keys fall off the TTY machine. However, to be nice, CW is not used with-in a busy phone band, but if it does not QRM a QSO, it is tolerated except by self appointed RF police. CW then, usually stays in the zone that ONLY CW is suppose to be in. THAT takes care of USA Hams IN USA. HOWever....there are other countries ( 2 at least I can hear) who's band-plans are like our 160 mtrs...everything-goes, mode wise.

Should we continue with the annual renewal of dues or would a post card notice of dues expiration work better when inserted into the last newsletter? Submitted by Bob, W1JLA. I know we talked about this once and I like what we do now better but its open for disucssion. 2. Should we limit terms of officers to 2 years or ? It would spred around the work so no one would burn out. 3. One of the HP Ham Club members suggested that the HP club elect officers on a rotating basis so that only one new officer gets elected each year and all others move up to the next position. 4. Maybe its time for some bylaws or a constitution which would include membership renewal? 5. The SSB net will meet at 8pm next week as a experiment with the hope to avoid changing skip and band condx. 72, Paul, W1CFI From qrp-request@Think.COM Tue Nov 23 09:44:35 1993 Return-Path: <01H5NF1TNTV49EDR2I@fair1.fairfield.edu>; Tue, 23 Nov 1993 09:41:53 EST Date: 23 Nov 1993 09:41:53 -0500 (EST) From: "D A Coleman (ext. 2850)" Subject: Re: More on wooden radios,6SN7 To: randy@cyphyn.radnet.com Cc: qrp@Think.COM Message-Id: <01H5NF1TNTV69EDR2I@fair1.fairfield.edu> X-Vms-To: IN%"randy@cyphyn.radnet.com" X-Vms-Cc: IN%"qrp@think.com" Mime-Version: 1.0 Content-Type: TEXT/PLAIN; CHARSET=US-ASCII Content-Transfer-Encoding: 7BIT Young Whipper_snapper, Om, my set was built in 1949.

You can do it with transistors now.--a sweetly operating regen--just as good as any tube job. And of course you can still make it out of wood. 72.4151883 W1VOQ From qrp-request@Think.COM Tue Nov 23 10:20:57 1993 Return-Path: id AA08650; Tue, 23 Nov 1993 10:19:07 -0500 id AA02678; Tue, 23 Nov 93 10:19:32 EST id AA22092; Tue, 23 Nov 93 10:19:16 EST Message-Id: <9311231519.AA22092@kaos.ksr.com> id AA11931; Tue, 23 Nov 93 10:19:14 EST To: bmitchel@cba.kodak.com Cc: qrp@Think.COM Subject: Re: NN1G enclosures In-Reply-To: Your message of "Tue, 23 Nov 93 06:08:48 EST." <199311231108.AA04021@hobby1.cba.kodak.com> Date: Tue, 23 Nov 93 10:19:13 EST From: "John F.

I am on three other mailing lists like this, and all of them have adopted the convention of prepending a certain short couple of letters and a colon to the beginning of their subject lines. For example, I belong to an amateur astronomy club at school that calls itself the Dartmouth Stargazers. We have a list, and everyone who posts something to the list uses SG: at the beginning of the subject line. So, a subject line might look like any of the following: SG: Perseides meteor shower this week SG: Aurora Update SG: Anyone up for a star party Friday night? With this convention, I can know just from looking at the subject of the message what list it is from - I don't even have to read the whole subject. This really makes it a lot easier to prioritize and read your mail, especially if you belong to multiple lists.

No Andrew, I haven't tried converting a CB radio for use on 6 meters; however, I see no reason why it can't be done. >I have a buddy (N8NVO) of mine who converted a 23ch Johnson AM/SSB to 6 meters, but it's bandwith leaves much to be desired. i.e. it dosen't cover the AM portion (like the calling frequency of 50.400). I'm not sure what you mean by bandwidth. Since it's a 23 channel radio you should be able to cover ANY 290 kHz portion of the 6 meter band. A 40 channel radio can cover 440 kHz. Incidently, some PLL chips in the older radios have an "unused" counter pin. By connecting this pin to Vcc or Vss through a pull- up or pull-down resistor, you can use a toggle switch to double the number of channels available. (No, I don't know specifically what chips those are or what radios they're in.) If you mean that the bandwidth is restricted because the performance of the receiver, transmitter, or both falls off sharply near the band edges, then I would suspect that the Q of the tuned circuits in the receiver rf stage and/or transmitter driver and final stages is too high or the low-pass filter was not modified properly. 73, Eric -- Eric Grabowski, WA8HEB al838@cleveland.freenet.edu Chagrin Falls, Ohio From qrp-request@Think.COM Sat Nov 27 19:30:09 1993 Return-Path: Sat, 27 Nov 93 19:29 EST for Think.COM!qrp id m0p3a0U-0000vAC; Sat, 27 Nov 93 19:28 EST Message-Id: From: andrews@fms.com (Andrew Sargent N8OFS) Subject: elm Filter ideas???

Becuase of the popularity of the NN1G transceiver, Paul talked to Dave (NN1G) about getting the artwork for the original NN1G rig, so that we might make some of the 20 meter rigs. Well Dave was really helpful, and sent the entire NN1G Mark II package that I guess is going to appear in QRP quarterly in January. Well, with this new artwork in hand, I set out to make the 20 meter version of the rig, using the Mark II artwork. First I made the two boards using the July, 1993 QST process for making p.c. boards. I'll be honest, the result wasn't the best, but definitely usable boards. Parts aquistion was a little work, but amongst my own parts drawer, and a friends parts drawer, I had enough parts to commence construction. For the crystal filter, I used 10 Mhz xtals, because they were available. To match them, I found that setting the 10 MHz source up on one xtal, and the measuring the response on a scope, I could match them easily. But you know, I really found that the particular xtals that I had , all of them were close enough! Once I had the xtals, and the rest of the parts, I decided to start building the Receiver board. This is because the VFO circuitry is on the Rx, and I wanted to debug as I built the circuitry. As I started stuffing the board, I found a minor artwork error, but I won't mention it, becuase I guess that the artwork is already being fixed. Anyway, I got around that problem, then fired up the receiver alone. Two problems were encountered. One is that there was a sound comming from the receiver that sounded a lot like precipitation static. But I noticed the noise even though the antenna was not connected. Well this bothered me, because I new I had a real problem. Well during the parts scrounging process, I could not find 78l08's right off, and looked at the specs for the NE-602 for it's max voltage rating. Well this was listed as 8 volts MAX! So I finally found a 78l08, and measued it's output as 8.18 volts. As a guess, I cranked down the 12 volt supply , and the noise went away. I got the meter out, and as the reg voltage dropped below 8 volts, the precip noise, now narrowed down to a breakdown noise, went away! So I replaced the 78l08 with one that had 7.8 regulated volts out. This cured the problem, but it may be something to note, that you may wnat to be careful with this if you use an 8 volt regulator. Problem Number 2. I found that as I increased the volume, that the LM386 oscillated at a high freq audio. This was cured by changing various caps, and I really don't know if this problem is something that I introduced, and then cured or not. Now the reciver was working great. The selectivity is fantastic! I can hear everything that my old Kenwood TS-520 can with the NN1G receiver! Transmitter construction was next. This took only a very short time to complete, and there appeared to be no artwork errors. I got this put together with one exception the output transistor. I found that a good 2n3553 seems to work pretty good in place of the recomended transistor. I am getting more than a watt out, but haven't measured on the scope with a dummy load yet. I next wired the two together , and was ready for putting it on the air. I listened, and everything was CQ test.... oh boy! I hate contests, especially all that computer generated garbage. Anyway, I'll have to wait till this "test of my will" is over for my first contact with the NN1G Mark II , but I predict that it will work 10x better on receive than the Spider. In retrospect, I might try to get 10.x Mhz xtals, something other than the 10 Mhz, because there is a little feedthru of WWV. I predict that will go away when I put it in a metal box. Also, I probably have $20.00 into this whole project, and I bet I'll make one for other bands, and then some. 73 all, and happy homebrewing!!!

If you have comments for Jim, send them to me and I will relay as he is not on internet. 72, Doug KI6DS My wife and I just returned from a trip to Idaho Falls, visiting Mac, W7JDZ, a member of Norcal. In the hills east of Reno, fired up and on a CQ, got a nice qso from Southern Utah. Out in the Nevada flats, worked four states, and many friends and five NorCal members. None were scheduled. A pleasure to have two QSO's with Bob, W6CYZ, and several with Mac, K6AGN, Mac, W7JDZ, Hall, N6SYW. Also, Forrest, N6ZBZ, in Redlands. All except one signal report was Q5, and I did get two QRZeds from stations I called. Most reports were 559 to 579. The antenna used was a Hamstick, mag mounted on the roof of the car. The NorCal-40 fit in the front of the console just exactly, and no ignition noise, albeit used the cig. lighter for power. The key used was a TenTec with paddle built in, a mate for the Century 21. Not the greatest, but my code speed was much, much less than my highway speed, so it worked fine. It sat on the back part of the console, and with my arm on the arm rest, wrist dangling off the end, it was easy to key. I made about 12-15 contacts on the way up, one lasting for 80 miles, a real ragchew. Could have made more, but why hog the band? Footnote: Put the rig on the Bird wattmeter to compare output with Mac's NorCal 40. Mine was putting out just over one watt. Yipes! I had not cranked the drive up after I tweaked the capicator. On the return, worked a half dozen stations, but with winds up to 50 mph, lots of trucks throwing up slush, snow, rain, tended to ruin my concentration of copying and sending. As for driving, this was across Nevada. Don't have to do much except correct the steering every so many miles. Purpose of this is not to brag (ahem). No, I've been QRP mobile before, so knew what to expect. Here, just want to say how well it works. Get that antenna up high, above a good ground plane. jim PART II In the mobile report sent out previously, I must have been doing a lot of ego satisfying, cuz I did not give proper credit to the NorCal-40, and to Wayne, N6KR, who designed it. The rig worked flawlessly, which I expected it to; perhaps that is why I neglected to comment on the rig. It is a pleasure to operate mobile. Tuning is smooth, and quickly zeros in on the desired station. Covers the allotted kilohertz without straining the arm, a plus in mobile operating. The RF gain control really comes in handy when the big guns are almost fracturing the front end. I used it a lot. All reports were complimentary as to tone, keying shape, etc., and some of the comments were from old time CW ops who DO know a clean signal. So, all credit to Wayne, N6KR, who has designed a QRP rig with superhet receiver, which is just as easy to build and get on the air as a direct conversion, supposedly simplier, rig. Just between us, Wayne's rig is easier! 72/3 jim WA6GER {By the way Jim is the co-founder of NorCal QRP club and is the one who packaged all of those kits for the NorCal 40}.

AMAZING how this was done on the budget 5. why can this little? club produce such and excellent publication and QQ which must have much more resources isn't very good When I joined the ARCI, I really looked forward to receiving my QQ. First I have received every issue describing QRP contests after the contest was over. The magazine is large in physical size, but the content wasn't up to even my lowest expectations. There are some good articles such as the NN1G, but all considered, very dissapointing. Anyway, Doug I personally feel that you did a fantastic job. I wish I could get you and the other club members to move to Tennessee so that I can come to the meetings and become active in a real QRP club that is doing GREAT things. Thanks and keep up the good work. 72 Jeff, AC4HF From qrp-request@Think.COM Mon Nov 29 09:56:56 1993 Return-Path: <01H5VQYOUUCMCP1RX3@tntech.edu>; Mon, 29 Nov 1993 08:58:46 CST Date: Mon, 29 Nov 1993 08:58:46 -0600 (CST) From: "JEFF M.

This is the $25 R&R kit version. I built the original Idiom Press 2 years ago and use it during contests and love it. Have no idea why I ordered this.. have about 7 keyers. Well if Doug wants I will write this up, but here is the short version: The kit was a bargain. The Idiom press came with a board and board components, you provide the case, the pushbuttons, the battery holders, the jacks. This kit came with the board, board components, 4 nice pushbuttons that have wires coming off them, a small speaker. My impression is the Idiom Press PC board was better quality. Some of the ground trace fell off the R&R version.. no problem.. didn't even need that part of the trace. I found with my Idiom Press that I turned the monitor function off anyway, so only needed the speaker for programming the memories and changing parameters. The R&R speaker was fine for this. I put my original Idiom Press in a fairly large Radio Shack plastic box and used large push buttons. This time I bought a real small Radio Shack plastic box with the metal top.. I think it is about 4X2. This keyer is really small.. didn't have room for the 3 AA battery holder and such.. Stacked 2 of the holders and kinda shoved the whole thing in the box and didn't even fasten anything.. the assembly is so tight, I didn't need to. I had carefully soldered all the components and wired up all the jacks and pushbuttons a while back and it didn't work. I knew I was careful and the bottom of the board looked real good. Had a bunch of stuff to do, so just put it away. Well I decided I should be able to fix the thing.. not many parts to it. I took out the Idiom Press version and measured all the chip voltages, and then did the same for the R&R version. I was somewhat surprised to find the voltages identical. This got me thinking-I took my multimeter and checked the output of the chip and found it was ditting and dahing. Traced down the problem. It seems that the enclosed parts layout shows the transistors in one way and the transistors that came with it are backwards from the version in the article (emitter and collector on oposite sides). The transistors were in fact marked (one for the speaker and one for the keying transistor). I pulled them out and had in fact blown them. I found one 2222 in my junk box and put it in for the speaker. I found that all the funtions were in fact working.. but wouldn't key.. was going to go to RS to get a replacement for the keying transistor. Decided I didn't want to go to town so took out a 3904? and used it.. made 25 contacts with it in the contest using the ARK40 and my Gap Vertical. The only other perculiarity was Z1.. the one in the R&R looks like a small cap and doesn't have a ground leg.. so there is an extra hole in the board. I really like the smaller size of this.. don't know what I am going to do with 2 contest keyers.. may have to put one in my HW9. Well I can't tell any difference between the functionality of the 2 keyers.. They are both the best keyers (even taking out all the capabilities of the CMOS) the keyer just works great as a keyer (even better than my 3 Curtis keyers). As a contest keyer, I still feel it can't be beat.. I like it better than the expensive AEA and have used both during contests. 72 Jeff, AC4HF From qrp-request@Think.COM Mon Nov 29 10:32:27 1993 29 Nov 93 10:32 EST id AA28241; Mon, 29 Nov 93 10:32:13 EST Posted-Date: Mon, 29 Nov 93 10:32:12 EST Return-Path: id AA02123; Mon, 29 Nov 93 10:32:12 EST Date: Mon, 29 Nov 93 10:32:12 EST From: rjl3f@shamash.cs.virginia.edu Message-Id: <9311291532.AA02123@shamash.cs.Virginia.EDU> To: qrp@Think.COM Subject: Paddles I'm getting ready to buy an new iambic paddle and am looking for some advise.

I have the NorCal 40 QRP transciever, but it is the first kit I will have built in the modern era, so I decided to build the CMOS Super Keyer II from R&R Research as practice. I have a couple of questions about soldering. My soldering procedure is this. I have an Ungar soldering iron with two speeds -- 25 watts and 33 watts. I use the 25 watt speed pretty much exclusively, since 33 watts seems to be too fast for my skill. The tip is 1/8 inch in diameter, and from the side looks like a church roof, kind of like this: /\ <-- The crest. / \ | | | | | | / \ / \ | | | | | | | | | | | | except that it's more symmetrical than I can draw with ascii graphics. It's flat on the sides, like a chisel. This picture is looking along the flat sides, so that the top diagonals are really a flat plane. I call the very top the *crest*, for lack of a better name. (If there is a better name, tell me.) When I install the parts I put the lead through the hole and bend it slightly (1/16 inch or so) along the adjacent trace. I then put the crest of the soldering iron along the lead and heat up the lead and the pad until the solder flows over both of them. 1.) The biggest problem I have is that when I solder the molten solder wicks up the iron, and I get little peaks over the pads. Maybe this isn't a problem, but my solder joints never look like the ones I see in commercially made equipment. 2.) The next problem I have is that I get a bunch of junk from the flux all over the board. Do I just clean this up with some carcinogenic solvent or other? Should I just ignore it? It seems aesthetically displeasing to leave things that way. 3.) The 1/8 inch tip seems very clumsy when used with this particular kit (the keyer.) There is a smaller tip, maybe 1/16 inch. Is this necessary? Is the 1/8 inch conical tip better? It seems like it would be clumsier than the chisel tipped one. I hope these questions are not too elementary.

I have enjoyed reading the comments of the various contributors; but I have not felt that I had anything to contribute so far. However, today I thought I would share my impressions of the items listed in the subject line. First, the NN1G I bought as a kit from Dan's Small Parts and Kits. Other than a couple of missing capacitors and the fact that I murdered a couple of the IF cans cutting off the leads (I ordered more from Dan) the rig went together fine. I took some windings off a couple of toroids to get the VFO into the 4 Mhz range and to get the transmitter to zero beat the receiver. (At least I think it is.) I finally was able to get it on the air on Friday, Nov. 26th. About 440pm MST (2340Z) I answered the CQ of an N8. He turned out to be in West Virginia and gave me a 579 on the signal. On the other hand I was hearing him about 559 (What does this say about reciprocity, Chuck?). However, shortly after we began the QSO some stronger signals came up nearby and I lost him in the QRM. By that time, as I started to tune around the band, I discovered that everyone had gone into contest mode, so I shutdown the rig. Maybe tonight or tomorrow I can try some more. In any case I have 1 QSO at a distance of about 1400 miles. I don't know what my power output is but I suspect I must be near the kilomile/watt level. Bye the bye, I have installed my boards in an aluminum box from RS. It is 5-1/4"x3"x2-1/8". It was a bit snug, and I had to pull Rx board out to do its alignment;but it does make for a compact unit. Regarding QRPp: I found it to be a fine publication. It seems like a tremendous bargain. Keep up the good work.

Let us also consider the environmental implications - if you go 25 times as long before you pitch them in the trash, it will slow down the rate at which this stuff accumulates in your neighborhood landfill (assuming that any sizeable part of the battery using population buys these devices). When you consider the slime that accumulates and reacts in these landfills and then leaches out of the soil into the water you drink, such product improvements make a great deal of sense......

A shortwave receiver for 41 meters might fit the bill; if you bought NE602s and LM386s in bulk, there's no shortage of real simple designs for simple (cheap) direct-conversion rigs (not ideal for shortwave listening, but tolerable). And, of course, it works for the 40 meter amateur band at the same time ;-).

They run quite well, and outlast the standard ni-cads by quite a long margin. We've re-charged them twice so far, not because they needed it but because we could. Others have reported less than spectacular results, however. They have a high internal resistance, so are not good in high-current applications.

Now, I believe that the ARRL sells the kits for $24.95 or so each, but I believe they're cheaper in quantity, not to mention the fact that the complete schematic was published and you might be able to scratch-build them cheaper still (ie, etch your own boards, etc). 73, Doug __ /| | Doug Renze, N0YVW | \'o.O' | +1 319 337 4664 | If you can read this you're too close. =(___)= | drenze@icaen.uiowa.edu | U | Douglas-Renze@uiowa.edu | On 29 Nov 1993, Bob Scott wrote: > Inexpensive Radio Project for Scouts > To all the fine folks on this list... > > Maybe you can help me out with something.

All of which is fine and good if you have the option of using elm. I am personally on a proprietary mail system that doesn't support filters and just shoves everything into the inbox, regardless of where, when, who, or what it is.

I think not, Chuck, parts may be getting harder to get, but that's because the demand is very high.

Boards are probably available from FAR Circuits. W1AW's 80-meter CW frequency is about 3581 kHz. That frequency is close enough to the US colorburst freq of 3579.545... kHz that you can use a colorburst crystal in the local oscillator of a direct-conversion receiver. Kits may be available for other W1AW frequencies if you live outside the coverage area of our 80-meter signal.

"A New Breed of Receiver" (Jan '88 pages 16-23) describes an SSB phasing receiver. It uses Mini-circuits SBL-1 mixers and some high- frequency/low-noise op-amps (I think) eg NE5534, NE5205, TL081. Favorable comments & suggested mods by Bob Zavrel appeared in September '88 QST (probably the Tech. Correspondence column). No NE602s. "A Portable QRP CW Transceiver" (part 1-Receiver: Dec. '90, pp. 44-47; part 2- Transmitter: Jan. '91, pp. 17-23) used MC3362/LM324/MC3340/LM386 in the receiver, and NE602/LM6321 + discrete transistors in the transmitter.

One caught my eye (it might have been the last one), written from a QRO, that basically stated: is it fair to them (the QRO) to expect them to deal with our weak signal? Especially when the QRO gives the CQ? Obviously he/she doesn't have to talk with us and could just CQ again, hoping for a louder reply. Many times we (the QRP) say "if I can hear I can work them" in championing our qrp units. True, as long as the other end is willing to deal with us. Apparently most are if we've developed this statement. I'd be curious as to what the lower threshold of signal strength the average QRO expects nowadays. Is it 599 as he/she is? Or are most people good and interested in the contact even if they have to work at hearing you? You guys have more experience than I do on this. Any ideas?

Apologies for duplicates. ] I'm looking to build a simple QRP wattmeter. I don't need something that is accurate to three decimal places; just a small box that would indicate if the RF output power was above some threshold. I was originally thinking of getting some of those precision light bulbs from Radio Shack and using them in a box with a couple of switches. The procedure would go something like: key down, switch to bulb #1, if bulb #1 lights up, your output is at least 0.25 watts, switch to bulb #2, if bulb #2 lights up then you have at least .5 watts, etc. When a bulb doesn't light up, you would know you are below that threshold, and above the previous threshold. Like I said, I don't need a high degree of accuracy, just a rought idea of the output power. I'd like to have certain threshold that I can determine if the output is at or above. I'm thinking about .25w/.5w/1w/3w/5w, but I actual values would depend upon the bulbs themselves. I'm not too certain that this whole bulb idea will work either. (I don't think the bulbs will look like 50 ohms to the transmitter, but does that matter for the accuracy of this project?) I'd like to hear comments from the group on any homebrew wattmeters that you use. It should be simple, easy to build, and shouldn't require any fancy equipment to get it calibrated. (Cheap is also a good characteristic :-)) ) Ideas? I'm listening.

If you make your own dummy load use carbon compositon resistors if possible (not carbon film which are the common "carbon resistors"). Design for a power dissipation at least twice your expected max power (the resistors get very hot if run at full power rating). The diode detector should be in the same case if you homebrew. Use a general purpose diode for QRP (1N914, 1N4148 etc.) anode to the input. A capacitor should be connected between the cathode and ground (100n parallel with 10n is good for HF. Use ceramic caps). By measuring the voltage across the capacitor with a HIGH impedance voltmeter the output power can be calculated from the voltage which is the PEAK voltage don't forget to allow for the diode voltage drop at low power (at higher power the error becomes small (0.4 dB at 2W). 73 Richard Urmonas VK3DRU From qrp-request@Think.COM Wed Dec 1 17:41:04 1993 Return-Path: id AA04892; Wed, 1 Dec 93 12:40:59 HST id AA10567; Wed, 1 Dec 93 12:40:58 HST Date: Wed, 1 Dec 93 12:40:58 HST From: Jeff Herman To: QRP@Think.COM Subject: QRP watt meter Message-Id: The lightbulb watt meter is something I've been pondering also.

I'm not a full time QRPer, but I've been called and QSO'ed by em and have run QRP myself, and YES...it is fun! Having done it quite a few times, right on down to 35 milliwatts, it started to get to where I said 'now what?' I enjoy building the sets, and I'm into tubes, so most what I have made in the 4 years sence I've been liecenced, has involved tubes. Sence, too, I am not afraid of CW ( its CW that drew me to Ham radio, but don't tell the anti-code guys that!), all my rigs were CW jobs, and ran off a crystal....well, one had a VFO, and made great morning dove sounds... This past summer, I put together a triode tube oscillator-output set, using a single #26, 4 prong tube....built as near as I could do it, to be how they did it back in the 20's ( but , I used a crystal rather than a wild oscillator, tuned more by the swaying antenna than the operator!) I lit it up, and it worked, until the filament resistor burned out. I contacted a couple guys on it who had no idea what a tube was, so, I said it was a qrp, home made set... and let it go at that...poor guys, not knowing what tubes were..... Then, it occurred to me that I never heard this thing at a distance.. So, I gave the set to N1KGY who is a new ham but is deep into home making too and was tickled pink to lite up a tube older than he was. Temporarily, having lost the filament resistor, we had to sub a 811A which let us use 6 volts for the filament, and with 110vdc, it put out about the same as the #26 would. A quick test from his site with it proved, that 1/3 watt would do it... so we aimed towards a nite to use the #26 ( 1/4 watt) once he got the filament resistor....to drop 6 vdc to 1.5 vdc. 80 meters is a mad house between dusk and midnite, so we'd try to get on before nite fall...ie...AT the start of dusk...when probagation would be 'good enough', altho low. That was the plan. Each nite, with the sked only of 3700kc, and sometime between late afternoon and past-dusk, I'd sit there and monitor 3700kc for his call. ( We normally sit on a freq anyway , to call/qso when air permits, so this was no major change from our usual radioing... except for the signal levels involved , and no warning he'd be on.) I'd hear other stations out there, but...nope..that one is an 8 call... and he's calling his ladyfriend again... to drive her crazy with his electronic keyer... ... nope... thats just someone trying to find where the plate tune knob is on their rig.... ( hurry up! dip the plate before you have a China syndrome on yer table there!) Then , one nite, when I had given up on him , with now many stations getting tuned up and 2 QSO's on either side, I heard... KA--N- K-1--W K----- de N--G- N1--Y K way out there and right smack under some one tuning up...all the sig did was shift in loudness! So, sence 'qrming' a tune-up is not possible, I zeroed in carfully to be the same pitch as he was on the receiver, and verified I was dipped, while he made his 2nd call to me...and the tuner upper was still finishing up... -A1U-- KA--- [ my tune up] KGY K I returned, with N1KGY de KA1UNW KN KN KN ( to make sure no one else roared in to steal the qso, as has happened several times in the past.)

Since the person who provides the kit can buy quantity he can get you cheaper prices and save some S/H charges.

Kits are a great place to start. They go together quickly, they work (usually), and a little staring at the schematic is educational. Then we build by gathering parts and following someone's published design. Then we take ideas from one project and try to incorporate them in another. This is the stage at which much smoke is generated (in the projects and in our ears.) Then we design some new circuits no-one has ever tried before and become famous! Needless to say I am floundering around in the first several stages, and having a great time. Let's accept kits as homebrewed. It will encourage kit companies, who then will have parts for us, and will help lure newcomers into the joys (!?) of building. As an aside, beer homebrewers do accept kit brews in their competitions, while the real fanatics sprout their own barley and grow their own hops. 73, Dan, KF4AV Daniel J.

All in all it was a learning experience too. I confess...I started with a Heathkit. (?!) + 73, Brian - AE9K PS How much beer can you brew at home before the ATF tracks you down?

I use an MFJ 9040 transceiver, a home-brew antenna tuner, and a gel cell. This combination works well and has been quite reliable. I built the tuner from a schematic for a QRP 40 meter antenna tuner in "Solid State Design" by Hayward and Demaw. I've tried slinky verticals, dipoles in the room, and random wires hanging out the window. The latter seems to give the best performance. Early this week I experienced something odd, maybe some of you can help. Monday night I set up the rig and tuned the antenna, I threw a wire out the window with an equal length counterpoise on the floor in the room. The band was not great but I was able to work NV from my room in San Jose, CA. The problem came on the second night, I set the rig up and started the tuning process. I found that the SWR would change just by touching or placing my hand near the metal part of the key or chassis of the radio. The first night I had no such problems, the setup both nights was the same.

Did anybody notice the add for Ten Tec Kits in QST? It says, "KITS ARE BACK! Introducing TT* Kits A new division of Ten-Tec Call 615-453-7172 to request your kit catalog" I just called and requested the catalog. I was told it would take 4 to 6 weeks. That was fine with me. I am still saving away, trying to recover from the recent local hamfest. So what I am dying to know is if I will be able to buy the Ten Tec Scout 555 as a kit? I wonder if I will be able to get kits for some of the band modules? I wonder if it will be possible to hombrew band modules to cover other bands or offer other features? I wonder... Has anybody seen the catalog? Well, I'll tell ya more next month. Also, does anybody know if the 291 Antenna Tuner for the Scout is an automatic tuner? I suppose not for $89. Has anyone tried the 607 Weighted Key Paddle for the Scout? Do you like it? Where does it plug in? How does the power adjustment work on this radio? Do you have an option to bypass an amp stage or do you just atennuate some of the final power? What features does a fancy Radio, like the Icom 735 have that this doesn't? I know that several people have pointed out that by the time you buy all the modules, (and the bracket, mike, etc. are all extra) you are paying two or three hundred more (depending on the accessories) and you could probably buy a nice used Icom 735 for that price. I would note, that in a couple of years you can probably buy a nice used Ten Tec Scout 555 for a little better than $495. Also I might expect the $495 to drop some over the next year or two. And If I can save some by building a kit, that would really be neat. Of course I am dreaming, and wildly speculating on that one. Ya, know, I would like to homebrew some type of interface for a computer, so that you could have the computer set the vfo frequency, etc. Then you could write a program to make the computer control the radio. "Virtual Radio." Then the program could always add all kinds of bells and whistle features, like all the memories you could ever want. Like scanning, like .... The computer could also handle the TNC. The computer can log the contacts. The computer can display the map of the world. You can point and click on the location of that DX contact and see the current time there. Sunclock on the Mac will do this and let you see where the gray line is at any moment. The ideal set up would be a notebook or powerbook computer controling a small radio like this mobile, or even while backpacking. BTW, Sourdough is good homebrew. Sourdough and Ham KG0IO --David C.

I found the project to be not very expensive, It is however accurate and its a directional wattmeter. You really have to etch a PCB for the project, but if your really aganst that I.m sure you could get around it. The circuit is small enough to be included into a transmitter project, thats what I want to do eventually.I found the Wattmeter easy to build, and I am new at Home brewing. The only problem I hade was winding the T2 and T3 toriods? with the proper phasing, but ater I figured that out it worked great, and still does.

Had a few problems along the way, and all were building related. Things to watch for 1) when you etch your own board (yes there are those of us who would rather HOMEBREW from scratch than send our hard earned money out) make sure it is completely etched. I thought mine was, but I found 2 little fuzzies (shorts) on the rx board. Fixed them, and the RX took right off. 2) Check each part VALUE carefully, my TX would not oscillate, and I found that I had put in 470 pf caps in the oscillator instead of 47 pf. Changing them, and off it went. This is a lesson to those of you you have a surplus or electronics store in your area that has the parts in cardboard boxes (don't trust what it says on the box, look and verify the value). Having just gotten it up and going, and making 2 quick contacts with area hams, I have two things I have to work on. 1) RX seems to have a little too much background noise. (Changed the .033 cap to .047 and the .005 cap to .1 and most of the noise went away, but still too noisy & thnaks to Brad, WB8YGG for that tip.) The RX does not offer full QSK it seems. When I was operating it at above about 13 wpm, the RX seems to act SEMI-QSK, any one got any suggestions to get it FULL QSK, what we gotta do, I haven't looked at the schematic about that yet??? Thanks to Brad WB8YGG for the use of his time and equipment to help me debug this NN1G Mark II, it is going to be a lot of fun running it. As for the LO & Xtals, I chose 10.240 Mhz and this puts the LO at 3760 to come up with 14.000. The rig seems to track from 14.000 to 14.067 with the standard values. I had to add 66pf to the LO coil to get it to come down to that freq. It first oscillated at 3918, 33 pf brought it down to 3818 and the next 33 pf (66 total in parallel) brought it right on at 3760. Brad, WB8YGG will be changing his IF also, his 10.000MHZ xtals let WWV bleed thru quite readily (even though it it not in a box yet) and mine does not. At least Brad can keep up with the UTC time on a minute to minute basis. Any furthur changes, and I will print here.

There aren't deep dark secrets, but you need to be careful in their application. First of all they have a very large negative temperature coefficient (typically N350, that is -350 parts / million / degree C). However, there are some pretty good temperature compensation techniques that can be applied to attain reason- able stability. Also their Q is somewhat limited compared to a air variable. Low noise VFO's require high Q tuned circuits. Again careful application can minimize the degradation. One last factor is that the diode basis needs to be higher that the RF voltages present in the circuit. Casual application is usually a poor result. They are small, cheap, available and can produce good results. There have been a few good articles published in QST and Ham Radio magazine over ther last 20 years. Motorola has some good application notes on their application too. 73 Ed W1AAZ From qrp-request@Think.COM Fri Dec 3 10:00:37 1993 Return-Path: id AA27420; Fri, 3 Dec 1993 10:00:13 -0500 id AA08088; Fri, 3 Dec 93 09:59:35 EST id AA03136; Fri, 3 Dec 93 09:59:30 EST Message-Id: <9312031459.AA03136@kaos.ksr.com> id AA26817; Fri, 3 Dec 93 09:59:26 EST To: Mark Shelhamer Cc: QRP@Think.COM Subject: Re: Varactor VFO???

It seems to me that their > much smaller size and mechanical stability, compared to air variable > caps, would make then ideal for QRP gear, especially backpackable gear. They suffer from two chief problems. First, their minimum to maximum ratio usually isn't very good; 3 to 1 is pretty typical for varactors, though you can find them as high as 15 to 1 -- only in very high maximum capacitance devices, however. This makes it somewhat difficult to choose circuit components around varactors, and exacerbates their other disadvantage: temperature stability, or rather their glaring lack of it. There are several schemes for temperature compensating varactors, but they usually either are just close enough to let a PLL take care of the rest with less effort, or they involve lots of empirical component selection. That said, there are some rigs that use varactors, and as long as you keep the temperature constant, they do quite well.

My evaluation: The kit: ------- *this is an evaluation comparing it to commercial kits.. so it is way too picky for what it was designed for- The artwork and instructions were good quality. The parts identification could probably have been a little better for a beginner.. but still ok. The schematic was first class as was the documentation, better than a good deal of the commercial kits out there. The packaging of the kit was excellent. The kit has a low parts count and everythink is on one board. The PC board is clearly silk screened. The parts on the board were not too densly packed and easy to place. The board was good quality. One of my personal favorite parts of this project was that most of the jacks and connectors were board mounted. There also wasn't many jumpers needed. This board design took a great deal of careful planning and came out on top of the heap in my opinion. It is really nice to finish building the rig and not spend 2 days running wires all from panel mounted controls and jacks to the board. The finished project also looks a lot better. The case is another TOP of the line item for this kit. It is GREAT. What do I mean by GREAT-well first of all it looks and feels as if you can through it out of a plane, pick it off the ground and continue a QSO immediately without any repairs. It also looks very nice. In addition, the case was also carefully designed so that if you want to remove the top and tinker with the controls inside, it is very easy to do so. I recently built the ARK40.. and loved it. Well I like to tinker with a new built radio till it feels right. With the ARK 40 it is pretty much of a major project to take the case apart and get to the bottom board. The only other rig that I have seen that does this is the MFJ QRP rigs. They also would make great kits and are very similar to the NorCal 40 in one board all on the board no wires all over the place design. I had a slight problem with the rig when I first built it. Turned out to be a blown capacitor and 2 chokes that were not of specified values. This is probably me and no one else had this problem as far as I know. I seem to be cursed with this. I built the HW9.. and each soldering joint was a work of art. Put it together and it didn't work. Has a bunch of people try to locate the problem. Finally got some good help and my friend traced the problem to the double balanced mixer. I was told by Heath that these parts are NEVER bad and I must have done something wrong building. Well my friend pulled a comprable part out of a homebrew he had made. Stuck it in the HW9 and everything worked... Moral of the story ... there are bad parts out there.. but don't worry the number is so small that I am probably the only one that gets them HI HI. The same guy who found the HW9 problem has been working on QRP designs for a while. I gave him the NorCal 40 to play with. The good news is that he hasn't shut up about the design of the radio. He said he couldn't see all that much to improve upon and loves it. He went into detail about how he felt that in the design process the designer would get to a particular part of the circuit and say.. "well how can I redesign this part to use common parts and make it uncomplicated". The bad news is that I think he has given up on his design.. said he couldn't think of what he would do different. I like the fact the radio has RIT, an on/off switch and is really small. This is about perfect size for a portable rig. I was really impressed with the receiver. Conard, WS4S had the rig to find the blown capacitor and other problems while I was on vacation. He got it running just in time for the CQ contest last weekend. He worked all over the world and said the front end of the receiver really held its own.. he doesn't give compliments easily. I really liked the keying, it seems to fit my style of CW. The sidetone note on the rig wasn't really to my liking, but this could have something to do with the way he set it up.. didn't have time to tinker with it. This kit is easily comparable and beats many of the kits in the $120-$160 range. Thanks guys ... boy did you do some job. 72 Jeff, AC4HF From qrp-request@Think.COM Fri Dec 3 10:39:57 1993 Return-Path: <01H61E88NGBKCQ9OYS@tntech.edu>; Fri, 3 Dec 1993 09:41:56 CST Date: Fri, 03 Dec 1993 09:41:56 -0600 (CST) From: "JEFF M.

It is the folks who are REALLY driven by a certain concept, ideal, or goal, who get out there and move mountains, develop the first PCs in their garages, find the cure for cancer, keep qrp and CW (yeeeaaahhhhhhhhh!!) alive, etc. Unfortunately, some of these folks combine this powerful and positive human trait with another powerful human trait - egotism. Egotism usually leads quickly to intolerance, hatred, and sometimes, cruelty and abuse! Sorry for the sermon, guys, but I just can't let remarks like have just come across the net go unchallenged. Saying that people who don't want to WORK for a qso, just BUY them with bux for KWs, and won't work anything but strong signals, have ceased to be hams (full stop!), is just out of line. C'mon guys, its a hobby! I fell off my chair laughing when I saw the ad with K7SS wearing fatcat sunglasses and chomping on a cigar with a s--- eating grin on his face, leaning on a linear (that he OWNS). You gotta be able to laugh at yourself, regardless of whether or not other people appreciate your own rarefied point of view, even about something like CW which is, as we all well know, is a CLOSED discussion (nod in the up-and-down direction, class, my HS math teacher used to say). It reminds me of the downright intolerance that many cross country skiing buffs have for the fat, non-environmentally conscious, money-and-fancy-ski clothes-with-only-Vaurnet-sunglasses, non-vegetarian downhill skiiers. Many of them also make a point out of telling everyone on the slope (as they go out of their way to be obvious that they are going UP the mountain, and not DOWN) that only theirs is "REAL" skiing. I remember from 20 years ago, when I was only a kid and had no opportunity to get into qrp, that the QRPers even then had a holier-than-thou reputation, earned or not. Let's not go and EARN it, for Pete's sake! Yes, yes, I agree that the bands would be a lot nicer, and more qrp stuff would be available with more features for less $ commercially, etc., if everyone out there thought as we did. But I still contend, there is NOTHING at all wrong with qro operation as a concept. A lot of hams just want to HAVE armchair qsos with their daily nets, skeds, etc. A lot of retirees keep themselves busy this way. And why not? Part of the hobby IS to try to maintain reliable communications for use when it may be needed. In my opinion, the biggest cause of problems on the bands is not the QRO, it is who is using IT. The exam process is just far too easy, and so there are a lot of lids out there clogging up the bands who just didn't have to learn and struggle to get their tickets. We don't even have to MENTION the CW req. It IS a privelege to get on the air, and many folks just don't respect that.

It seems to me that their > much smaller size and mechanical stability, compared to air variable > caps, would make then ideal for QRP gear, especially backpackable gear. Yes and no. In addition to the undesirable temperature characteristics others have mentioned (though compensation techniques are well known), the DC you apply to the varactor must be absolutely clean or it will frequency modulate the oscillator's output. Which is how many FM transmitters do it, but is not what you want for a CW or SSB transmitter. This includes control voltages. The pot you use to adjust the oscillator frequency must be a good one to avoid transients making a mess of your frequency, and also so that it won't wear out from excessive use, which cheap pots aren't designed for. You want the highest quality 10 turn pot you can lay your hands on for such applications. Since any reverse-biased PN junction will exhibit a space charge and thus variable capacitance, many projects that use varactors can work fine with many diodes. Zener diodes can work well as varactors, and even a lowly 1N914 will do well if you choose the right one (the Ramsey DC receivers use them, with a Zener diode for voltage regulation). The junctions in many bipolar transistors will work well too. 73 from Burnaby laura VE7LDH From qrp-request@Think.COM Fri Dec 3 13:56:07 1993 Return-Path: id AA24166; Fri, 3 Dec 93 13:58:17 -0500 Reply-To: bmitchel@CBA.Kodak.COM (5.65c/IDA-1.4.4 for ); Fri, 3 Dec 1993 13:08:12 -0500 Date: Fri, 3 Dec 1993 13:08:12 -0500 From: Brad Mitchell Message-Id: <199312031808.AA16697@hobby1.cba.kodak.com> To: qrp@Think.COM Subject: nn1g mk II Well, last night I coudn't sleep, so I turned on the 20 meter nn1g mk II , and walah there were a bunch of VK's and ZL's right there for the picking.

Unfortunately solid state rigs are not as tolerant. A cold filament will look like nearly a dead short to the transmitter; it is a race between destroying the final output stage and heating the bulb. There are some easy circuits in the handbook for QRP wattmeters; the principle is something like the following:i 1n34a 100uA meter RF in ---+-----*|----+--------O---gnd | | / 50 = 100pf \ | / gnd gnd A pot across the meter may be required for calibration.

Wondering why Dave kept some of the traces so small in some areas. I'll move over the parts list and schematics for NN1G Mark I. Sorry, I don't have the art work in machine format. I'll let you know when I move it over later this afternoon. For the individual who just finished the Mark II, and I apologize for not writing down the info but it's off the screen forever, the noise may be reduced by reducing the resistor value across pins 1 and 2 for the MC1350 IF Amp. Try 5K and 2.7K values to see the effect. I have played with this on my 40M version and I don't think that the overall sensitivity of the rig was decreased enough to worry about it. I've seen some designs with lower values, but this is probably an individual preference. Dave's original value in the Mark I (which I assume is the name, since he calls the newer rig the II) was 10K, certainly too high a resistance. As for the QSK timing, the capacitor from the Gate of Q2 (MPF102) may be reduced in value to speed up the receiver recovery. I haven't played with this as it was not a problem on the Mark I. If someone has the schematic for the new rig and can fax it to (214) 788-1376, I'll change the Mark I to match the new version and put it on Think.COM. Ok, i've moved the files nn1g.mark1.ps and nn1g.parts to Think.COM. Bruce will put them in the artwork directory. You just send the nn1g.mark1.ps file to a postscript printer and you'll get the schematic that's in the Jan '93 issue of the Quarterly, but it's from my schematic program. I don't think it has any errors and it has no mods. If the lines are too wide, add a line '0 setlinewidth' after the other set* lines somewhere near the beginning of the file. I just forgot to do it and I've asked Bruce to do it, but he might not get a chance. Just in Case. :-) I have marked the parts with typical markings found on parts in the junk box for the people new to building, etc. Some variations may occur. Refer to the ARRL Handbook for parts markings, etc. The parts file is just plain ASCII text. I have another set for 40M if that is your preference. I just didn't want to load WT1M's system up, and I can do that. :-) I just got yesterday a new copy of Dan's Small Parts Catalog. He's got some great deals. About 6 typed 8.5x11" pages full of goodies just in time for Christmas season. Also a 10% discount (or was it 15%?) for ordering before Christmas. I listened to 40M on the NN1G Mark I on the work this a.m. The first time in a long time. There was an AMTOR station about 7.005MHz. Is there no honor anymore?

They are willing to get into the kit business as much as is profitable (don't take this wrong.. basically the want to produce High Quality kits as long as there is a market for them.. as the market shows them it is alive, they will expand their offerings) first stage: 10-15 small single board one nighters such as audio amplifiers (I think he said under $50) second stage: 5-10 projects like receivers and QRP transmitters in the $40-$100 range, one will be a 2 meter brick couple in about 30 watts out By Dayton: 2 meter synthesized programmable 2 meter transceiver- about 10 channels for under $200 [put me in for one] that's it so far. The catalogs and first kits should be available in a few weeks. 72 Jeff, AC4HF From qrp-request@Think.COM Fri Dec 3 15:49:32 1993 Return-Path: (5.61/UUNET-internet-primary) id AA24587; Fri, 3 Dec 93 15:49:28 -0500 (queueing-rmail) id 154705.15382; Fri, 3 Dec 1993 15:47:05 EST id AA07115; Fri, 3 Dec 93 14:19:58 EST Date: Fri, 3 Dec 93 14:19:58 EST From: epacyna@auratek.com (Edward Pacyna) Message-Id: <9312031919.AA07115@auratek.com> To: qrp@Think.COM, uunet!zk3.dec.com!cranston@uunet.UU.NET Subject: Re: K1BQT kits from Radio Kit I've built 4 or 5 of them (20M and 15M versions). This kit has been around since 1990. See CQ magazine, Sept 1990 for construction article. FAR sells PCB for $12 (same as in kit) if you want to homebrew one. Also the MFJ 90xx transceiver is based on this design, but with some changes and bigger PCB. With a few modifications, it makes a decent transceiver. 73 Ed W1AAZ From qrp-request@Think.COM Fri Dec 3 15:53:37 1993 Return-Path: <01H61P4A458GCQ9OYS@tntech.edu>; Fri, 3 Dec 1993 14:55:31 CST Date: Fri, 03 Dec 1993 14:55:31 -0600 (CST) From: "JEFF M.

Q >--------------------- Spence and Gang: I can't be much help on your problem with the SWR. I am a reasonably new Ham (9 Months) and a newbee homebrewer (9 months) I am however VERY intrested in your experiences in Hotel room QSO. I have been trying to build something Q for just this use, I spend most of my work life on the road, and the antenna problem has been my major stumbling block. I am building a 30 Mtr rig for hotel rooms because I thought the ant would be easier to deal with. Please tell me of your experiences with the various antennas. How long is your long wire, what about the counterpose? I would think a short wire would be difficult to tune, do you just drop it out the window? What about when the window does not open? What do you do for a ground? How do you like the MFJ 9020 ? (although i'd rather build something my self:) Which ant tuner did you build? I am starting to think about building one myself. I am considering the "A NOVEL RESONANT ANTENNA TUNER" from the W1FB QRP note book, but building it with toroidal coils like the one in QRP Classics page 228 of the same design. I would like to use small caps like the Harmmarland APC 140 , although they might not have enough capacitance so I would have to maybe switch some more into the circuit. My goal is to keep the size small and then build it into my rig. I would like to hear your thoughts as well as from anyone else. Talk to you all later --------------------------------------------- Bob Berlyn bob.berlyn@Chowda.sbs.com N1PWU * OFFLINE 1.54 ...............................................................................

If you do (or perhaps a receiver might work?) build a simple oscillator with switchable (clip leads?) for where the LC goes... I have something like this (from an article in QST within the past decade). It can be calibrated by measuring an unknown LC (both unknown) by itself and with an additional known C (call it Cdelta). Since L*C = 1/(2*pi*f)**2 once you measure the two frequencies (F1 and F2) you can calculate the two LC products for each frequency (LC(1) and LC(2)). Lx * Cx = LC(1) Lx(Cx + Cdelta) = LC(2) Lx * Cx + Lx * Cdelta = LC(2) But Lx * Cx is just LC(1) so LC(1) + Lx * Cdelta = LC(2) and Lx * Cdelta = LC(2) - LC(1) resulting in Lx = (LC(2) - LC(1)) / Cdelta Now that you know Lx you can calculate Cx PS: Keep in mind that Cx includes stray capacitance of the inductor too...
