Rick kf4ar >------------------------------------ My approach for 160 meters was to build a transverter, which took output from the stage before the driver (with rig set to 40 meters) and fed output back into the PA brick's driver; then I use an external lowpass filter. The receiver taps off after the diode TR switch, and converter goes into receiver. I put extra phono plugs into the back of the rig, and have reed relays to switch transverter in (no plugging in and out!). On 160, the PA doesn't put much out, probably because the transformers are too small, but it works. I used the transverter circuit from the 1988 handbook; probably adaptable to other bands. If you don't want to give up the 10 meter segments, you might build external premixer, xtal oscillator, and bandpass filter, and route the PTO to it, finding a way to bypass the internal circuits. Haven't thought it through, but just a possibility off the top of my head. I'm guessing the output lowpass filter for 15 meters would do OK for 17 meters, and the 10 meter filters for 12, so you wouldn't have to add any bulky filter stuff where there's very little room!

Hey gang (qrp and boatanchor) -- I need some information if you can help (E-MAIL DIRECTLY ONLY). On the Usenet rec.radio.amateur.policy list lately have been threads suggesting changes to the current U.S. license structure. A major goal of about a dozen of the more vocal people in a restructuring is to either do away with a CW requirement completely for HF access (say to 10 meters) or reduce its speed (down to 10, 8 or just 5 wpm period). Anytime someone tries to chime in with support for keeping the CW requirement for HF access, they get flamed and drummed right out of the discussion. The anti-CW types suggest that a CW requirement is outdated, irrelevant, hazing-only, and other reasons to see that it gets removed. I am looking to put together a good set of reasons for why CW should be kept as a requirement for HF access. You are people who use CW, at least many of you (I don't mean to speak for anyone who doesn't; forgive me if it sounds that way), so can we come up with reasons, good ones if needed, to counter what appears to be a growing movement? I know we should be come up with reasons like lower power requirement, less bandwidth, etc., but the anti-CW types don't see those as pertinent in today's higher-tech hobby. Plus, Bob, they take the loss of CW (or lessening of it) in Maritime as further signs it is dead or dying. CW has had its day, they say, but not it's time to push on to spread spectrum, etc. If any of you really don't think CW should be required for today's access to HF, then let me know that too, with your reasons in support of that. I am trying to stay objective here as much as possible. PLEASE E-MAIL ME DIRECTLY, as the responses are not pertinent as a whole to either the qrp or boatanchor e-mail lists. I just chose these groups as a possible set of amateurs separate somewhat from the Usenet crowd (although there is overlap certainly). The Usenet crowd (the mass beyond the couple dozen or regular speak) are pretty quiet, whereas I know the members of these groups here will respond, and respond with reason and thoughtful words, not just quick passion or advocacy. Thank for use of the bandwidth. Happy Holidays. See you on the flip side. 73 de Kevin Anderson, KB9IUA * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * Kevin L.

Drop me a note telling where you are and I'll get the catalog to find the nearest office. Another good place for such parts is to scrape them off dead computer boards (I get a lot off old 2400 baud, dead modems and dead CD ROM drives where I work ). Use a heat gun and tongs to heat the board up, then take the flat edge of a butter knife to scrape them off. Use *really good* magnifying glasses to read the values, and if you're doing more than 1 board wear a glove when holding the knife (it gets hot too). -->jjw jjw@seastar.org -- John Welch, N9JZW From qrp-request@Think.COM Sat Dec 25 22:26:04 1993 Return-Path: id m0pDm3I-0001kOC; Sat, 25 Dec 93 22:21 EST Message-Id: From: randy@cyphyn.radnet.com (Randy) Subject: unsuscribe To: boatanchors@gnu.ai.mit.edu (boatanchor mailgroup), qrp@Think.COM (mailgrp -qrp) Date: Sat, 25 Dec 1993 22:21:55 -0500 (EST) X-Mailer: ELM [version 2.4 PL21] Content-Type: text Content-Length: 339 UNSUSCRIBE too many failed mails and when I post, too many complaints. -- 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!

The receiver is built on a 5"W x 3 1/2"D, double sided, gold plated PCB. 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. Price does not include the few components that are chassis mounted (e.g. jacks, pots etc.). Full documentaion included.

Well, funny that you should ask Bob. I've never seen one, but I've been getting calls from a ham in Plano TX, about 30 miles east of me, almost nightly for the past week about their kit. He has one for 30M and is about to complete it. His name is also Bob. This is his first kit and it sounds like it's going pretty well. His questions are mostly questions that anyone would ask about winding their first toroids, etc. I may get to see the rig in the next week and Feb at the latest when the local QRP group has it's bimonthly meeting on the first Saturday of even months, except June when we meet at HamCom in Arlington TX. He is FAX'ing me a copy of the schematic tomorrow, as I talked to him a couple of hours ago before seeing Bob's posting here. I have heard a number of rumors about RadioKits, but don't want to discuss them in an open forum such as this. Maybe someone else has some of their kits and can give us real data points on quality, delivery, etc. I received another Dan's Small Kits and Parts 30M NN1G Mark II kit on Christmas Eve. Just to show this group how disciplined I really am, it is still in the bag. I will start on it in a few days, but I'm working on the K5FO Special some more. The boards for the Mark II are exactly like the ones on the Think.COM system (see previous posts by others on this group). FAR Circuits has the boards for $10.50 (rcvr es xmtr) including postage. I got a pair of those boards also. They are single sided and silk screened and drilled. You just have to hunt up the parts. I'm working on getting another set of parts list for the Mark II on the server this week. The NN1G Mark II is capable of being set up for 80, 40, 30, or 20 meters at the present time. Dave, NN1G, says in the newest article that 3 of 4 rigs that he has built have oscillations due to the use of sockets, thus he is recommending not using sockets for the ICs.

Between 00:00Z January 1, 1994 and 23:59Z March 31, 1994, NorCal 40 owners will attempt to work as many states as possible in the United States. QSL's must be in hand to count, but are not required to be sent in. The first person to work all 50 states, or the person working the most states, will receive the K5FO trophy, to be presented at the Dayton Hamfest if the winner is present, or at some other suitable occasion if not present. For QSO's to count, they must be made with a NorCal 40 and a QSL must be in hand by March 31, 1994. Entries will be mailed to Steve Cates, KC6TEV, NorCal Awards Manager, Sacramento, CA. His decision as to the winner is final. Entries must be received by April 10, 1994. To enter, send a list of contacts, arranged alphabetically by state, with the following information included: Call, QTH, Date, Time, Frequency, his RST, and your RST. The application must be signed by 2 other amateurs attesting to the fact that they have seen the QSLs representing the claimed contacts. DO NOT SEND QSLs!!! In case of a tie, earliest QSO time of the last contact will be the tiebreaker. [K5FO is eligible for the award.] --------------------------------EOT----------------------------------- First: I will not be entering the contest, so the last remark does not apply. :-) Second: I'm showing contest to this group, as a number of you may have NorCal 40's at this time and not know of the contest. Third: As fellow QRPers, it is our duty to listen for and work as many of our fellow amateurs as possible during this time. Fourth: This is not a serious type contest, so no flames please. It's purpose is to generate activity as much as possible. We need to show the rest of the world that QRP is not dead and we don't need an Alpha 8x to work stations and have fun. :-) Fifth: CW is not dead. CW ops will continue to be around and work others. Long live CW. :-) :-) ;-) Sixth: Since most of the rigs will be in 6 land, do you think that the winner will be a 6? Inquiring minds wanna know. My guess is a no. Reason - guys/girls on the east coast have a definite advantage over the rest of the states. Why, in Texas, you could put 10 or so states (maybe some stretching here) in the same area. :-) My guess would be that there are probably over 150 NorCal 40s out there now. Maybe Wayne or Doug could give us a count, both on the number of NorCal 40s and the number of NorCal 40 members. My member number is 40. Should we get Bruce to issue us numbers for this group? Seems like we live by the numbers. :-) OFF SOAPBOX. FLAME SUIT ON.

I never got it to work well, very unclean transmitted signal. It could easily have been entirely my fault, though. I've ordered several things from RadioKit, and only had delivery problems once; an order for a cabinet that was to be drop shipped from the factory apparently got dropped (:-) and I had to call a couple of times to get him to remind the factory of the order. He won't win any congeniality prizes, but he did eventually get the thing shipped. Overall, my impression is that RadioKit is OK, but he's no Danny Stevig. 73, John, WB7EEL From qrp-request@Think.COM Wed Dec 29 11:44:05 1993 Return-Path: Dec 1993 10:43:28 CST 10:42:20 GMT-5 From: "Kevin Anderson" Organization: Augustana College - Rock Island IL To: qrp@Think.COM Date: Wed, 29 Dec 1993 10:41:56 GMT-500 Subject: 7.040 Priority: normal X-Mailer: PMail v3.0 (R1a) Message-Id: <11955A10E1F@augustana.edu> Did I read this right: the January QST, in its list of calling frequencies (same page as the W1AW schedule; I left my copy at home), listed 7040 as the Int'l RTTY DX calling frequency?

That frequency was chosen to avoid the European phone band. In Europe, the 40-Meter QRP Calling Frequency is 7030 kHz. Hereabouts, 7040 is frequently clobbered by the keyboard modes anyway, and they're growing in number. I find that $500 worth of audio filters hooked up to my inexpensive QRP rig usually lets me work through them. Save your stamps, or write about something else, gang.

The Radio Kit 20 meter QRP kit. The box is a ten tec enclosure.. haven't really done anything with it. The box looks good.. smallest QRP transceiver I have seen to date. It is from the Rich Littlefield design.. which should be ok.. has a built in audio filter that can be switched in or out, AGC, RIT. The new directions that are really for the new line aren't out yet.. but I didn't really want to wait. The directions seem a bit confusing, may have to throw them away.. HI HI.. seems that they could have possibly shipped one of two tx/rec relays and depending on which one they sent, you wire it differently.. think one has a diode in it.. they give you a test to check it out.. also the directions are really for the 15 meter (original version) so the 20 meter stuff is presently tacked on a couple of sheets on the top.. as a matter of fact, for the 20 meter version there seems to be some parts that are tacked on to the foil side.. not sure I like that.. sounds like should have done something for each band.. but don't really know yet. Also got the NN1G II from Dan's small parts.. have had a nice case for it for a while. 72 Jeff, AC4HF From qrp-request@Think.COM Wed Dec 29 19:40:23 1993 Return-Path: <01H728L043HID1I684@tntech.edu>; Wed, 29 Dec 1993 18:42:53 CST Date: Wed, 29 Dec 1993 18:42:53 -0600 (CST) From: "JEFF M.

I took it apart when I got home from the ham fest and noticed unattached wires, also noticed that the docs the guy gave me with it didn't match it. Turns out it was a 624 Kits VFO-2 in a really nice case with on/off switch and power light. Well, left it in a drawer for a year and a half.. got the documentation from 624 kits. Built the Spider recently and thought it would be neat to have a VFO controlled Spider. This week I took the VFO-2 apart and resoldered all connections and rewired a bunch of stuff.. worked fine the first time.. covers more than the whole band, took about a second to adjust it (one variable cap to set lower end frequency as I remember). Left the counter on it for a long time, appears to be stable. Now all I have to do is figure out where in the Spider circuit to put the output from the VFO... should be fun. 72 Jeff, AC4HF From qrp-request@Think.COM Wed Dec 29 19:44:55 1993 Return-Path: <01H728QKVGOCD1I684@tntech.edu>; Wed, 29 Dec 1993 18:47:27 CST Date: Wed, 29 Dec 1993 18:47:27 -0600 (CST) From: "JEFF M.

We go there to do some hiking (my son goes there to play video games, but make him hike all day to go gaming at night). Well we had heavy rain all day yesterday, the family wanted to go shopping.. I asked for directions to take the backroads from Gattlinburgh to Ten Tec.. beautiful 20 min. drive on country roads. The salesman took me to the "play" room and explained the Omini VI very thoroughly, then let me stay and play for about 3 hours or so. The rig is front panel tunable to very low power.. way less than 1 watt. Very impressive rig.. did a bunch of CW.. and even figured out how to do the thing with the mike.. think it is SSB or something like that... even talked to a guest operator at W1AW... he said it was like being DX working from HQ.. had a bunch of success with my portable/Ten Tec. they had a bunch of shelves full of old gear.

Ed, W1AAZ, a great contributor to this group and a technical whiz kid showed up at 0200Z or there abouts. I was just a about 10 minutes late. Heard him but he didn't hear me. He then worked a station to the west of him (come to think of it, EVERYTHING is to the west of him :-) ). His signal became stronger at 0230Z and held solid until we quit at 0258Z. We had nice qso for almost 30 minutes. He was running his homebrew at 5 watts and I was running the K5FO special. In fact, Ed was the first live qso with it. Finally got if off the dummy load. :-) Either we were both rock stable or both drifting at the same rate in the same direction. He had his new Idiom Press CMOS II Super keyer. He had it singing like a bird and error free for almost the whole qso at 25 wpm. Who says that builders can't operate? Enjoyed the qso Ed. At my 0.95W, that qualifies you for 1661.06 Miles/Watt.

And most folks want to keep them -- excellent backup/portable/QRP/QRO rig. The guy I got mine from had used it mobile and taken it all over the place on planes. It had been beat up a bit, the VFO knob bashed in, but he was a metal worker and made a support frame for the VFO that apparently was better than the factory! They sell at about $400 if they ever show up in QST ads. I got mine for half that -- with filters and accessories! He was probably apologetic for beating it around -- but he actually improved it. It is the slickest little rig for its type. I could use the better SSB filter -- more "other side" than I'd prefer. Have used it in a tent at night off a battery. And the fast QSK works for AMTOR, though I got better results with lower audio tones. Just found out from the ARRL files at world.std.com that there is a rebuild kit for the mechanical parts of the VFO.

Meetings are held the 1st Sunday of each month starting at 11:00 at the California Burger Restaurant at the Santa Rita Exit of I-580 West of Livermore. Membership to NorCal is open to all and is free. To become a subscribing member, you need to send $5 to Jim Cates, WA6GER, 3241 Eastwood Rd., Sacramento, CA 95821. That will get you 4 issues of the Journal of the NorCal QRP Club, QRPp. The last issue was 60 pages in 5.5 x 8.5" format. Jim is also taking orders for the second run of the NorCal 40. They cost $89 plus $4 for shipping. Jim reports that 47 of the rigs have been sold and we have 53 left. The parts have been ordered and as soon as we have them we will ship. The cases have been promised the third week of January, and also the boards. So it looks like the likely shipping date is some time in February. Please be patient as we are at the mercy of our suppliers. The January meeting of the NorCal QRP Club was another smashing success. 40 members showed up and the meeting place is sure getting crowded. Lots of old time members and several new ones at this meeting. People are coming from as far away as San Francisco, San Jose, San Carlos, Dos Palos, Merced, Atwater, and Sacramento. Several are coming over 100 miles one way! Membership is now over 240 with 210 subscribing members. The main topic of this meeting was the mods being made to the NorCal 40. Jim Pepper had 2 of them there. First of all, he has a working prototype of the digital display for the NorCal 40. Yep, you read it right, a digital display. Jim is going to write up the article for the March issue of QRPp, and it will include a schematic, artwork for the pc board, and a list of suppliers for the parts. Cost should be around $25, depending on the cost for the pc board. Jim developed this as a favor to me, and is graciously going to put it in the public domain. The club will pay for the development costs to have the pc boards done by Far Circuits, and you will be able to order boards from Far Circuits. Money for this will come from some of the excess funds from the NorCal 40 kit sales. Far usually charges $50 to $100 to do the first boards, and then they sell them for about $1.25 per square inch. Looks like this board will be about 4 or 5 square inches. Details will be in the March issue of QRPp. Jim also built a tuner/swr/watt meter in one of the "plain" NorCal matching cases for the NorCal 40. It was really gratifying to see, as he used the Stockton circuit out of the first issue of QRPp, and two of the meters that I gave away at the last meeting. Everyone oohed and ahhhed at the neat work that Jim does. Bob Lai and Terry Young are also working on tuners and watt meters. They are still in the process, but should be finished by the next meeting. Steve Cates has a new set of paddles that his wife gave him for Christmas. They are from England, and are about 2" by 1" with a strap that holds them to your leg. Really cute, and they have a great feel. Steve's dad, Jim, is already thinking of how neat they would be to go mobile with the NC40. Wayne Burdick brought his Mac Powerbook computer with graphics of the new NorCal project in the works, the Sierra. It is going to be a multiband rig with plug in modules for the bands. It will be on 80 through 15, including the WARC bands. Should be available some time this summer. Wayne has breadboarded several of the plugins and they are working great. He is calling it the "big brother" of the NorCal. Several of the features of the NorCal are kept, and several improvements also. Stay tuned for more details. Martin Jue donated some MFJ CWF-2 audio filter circuit boards and Joe at ACE Electronics in Sunnyvale donated the LM747 ICs and we gave them away at the meeting. Several guys went home with a smile on their faces thanks to the kind generosity of Martin and Joe. Several have promised articles for the next issue of QRPp. We are planning on it being a NorCal 40 "special". So far we have been promised articles on the following mods; Converting the NorCal to 80 meters, Converting the NorCal to 30 meters, 2 increased audio output mods, a mod to strengthen the front and back panels of the NorCal, digital readout, putting a tuner and Stockton meter in a NorCal case, increasing the power output to 5 watts, and 2 different articles on how to increase the coverage from 40 Khz to 150 Khz! I am also interested in articles about your experiences of building the NorCal. Write a review of the NorCal and submit it. We want to know your thoughts and experiences. Tell us how to make it better, what you liked and what you didn't like. Deadline is Feb. 1st, and Jan. 20th would be even better. Have a good month and hope to see you at the next meeting. Send articles for QRPp to: Doug Hendricks, KI6DS 862 Frank Ave. Dos Palos, CA 93620 Prefer on disk in ASCII format, but hardcopy fine. Send it in, and I will get it published.

I found that a 2n3725 switching transistor worked quite well to attain 1.0 watt out. (1W has been sufficient for me so far) This was the first contest I had participated in, and found it to be a lot of fun. I guess that I'm hooked, at least for the easy paced, qrp contest. All in all I made 32 contacts for just a few hours of operating off and on. And I even ran into NN1G himself , and chated for a couple of minutes about the nn1g Mk-II rigs that I made. Oh yeah... with the the 20 meter nn1g mk-II I talked to Fench Guyana over the holiday. Just 1 watt and an inverted vee! 73 all and happy 1994. ----------------- | ___ ________ | Bradley S.

Worked only 41 stations.. but wasn't on that much. 72 Jeff, AC4HF From qrp-request@Think.COM Mon Jan 3 11:00:42 1994 Return-Path: Date: Mon, 3 Jan 94 11:05:57 EST From: bapplega@isd.csc.com (Bob Applegate) id AA09025 for qrp@Think.COM; Mon, 3 Jan 94 11:05:57 EST Message-Id: <9401031605.AA09025@isd.csc.com> To: peter@ouzo.brooks.af.mil, qrp@Think.COM Subject: Re: QRP kits. I never built the Ramsey QRP kits, but have worked with some of their other kits. Not bad for a first-time kit, but the designs are ancient, lack common features, and generally don't work all that well. I was very disappointed in their keyer and 220 receiver. The keyer was HUGE and had a very old design to it. No dah memory, and the schematic/parts placement diagram/instructions all differed!!! It works, but I try to avoid it. The 220 receiver has cheap parts, doesn't tune well, and the case kit has no calibration, so I had to borrow someones 220 HT to calibrate the dial. Poor quality stuff... you'd do better building something from the QRP handbook or from other manufacturers. 73 Bob From qrp-request@Think.COM Mon Jan 3 11:04:00 1994 Return-Path: <01H78PTL9XQGD1IJ9R@tntech.edu>; Mon, 3 Jan 1994 10:06:28 CST Date: Mon, 03 Jan 1994 10:06:28 -0600 (CST) From: "JEFF M.

Good part: real small, has built in audio filter and RIT Bad: I am extremely dissapointed so far in the quality of this kit. I think the Norcal 40 was a MUCH more professional venture. The schematics, directions and all were of a much higher quality. The board on this is not silk screened, this combined with closely packed parts and other things makes this a real challange. The instructions, schematics and such bring four letter words to my mouth. I find the schematic very not fun to read, ok for a student ruffing out some plans, but the worst I have seen so far. The majority of the instructions deal with changes to the kit. Now I can see having changes, but get them organized. As best as I can tell the board is for the original 15 meter kit (it is labeled so). And then you tack on stuff and change parts and such to get 20 meters. The first page of instructions gives you a list of mods and parts to be tacked on to the bottom of the board.. I don't really like to tack onto the bottom of a board. There is a page that describes the way to test the relay to see if it has a diode or not..then you have to modify the circuit depending on which relay was sent to you. There were some more not clear pages of mods and changes.. yup that is the extent of the instructions.. again I don't think I would mind if they were clear and in some reasonable order. VERY unprofessional.. think the NOrcal group needs to take over the company.. the parts holes are at angles and such.. this combined with the handrawn board overlay.. is very confusing.. be prepared to work with the schematic for parts placements Well this is all personal preferance.. for me it would have probably been easier to have the parts and ugly contsructed this one. I think if it was done correctly this could have been a great kit.. smallest box and it is from Ten Tec.. There are suppose to be some new directions coming out. 72 Jeff From qrp-request@Think.COM Mon Jan 3 11:23:05 1994 Return-Path: Date: Mon, 3 Jan 1994 08:23:01 -0800 From: Joe Gervais Message-Id: <199401031623.IAA21894@weber.ucsd.edu> To: qrp@Think.COM Subject: It's official - I'm hooked Cc: jgervais@ucsd.edu (Pardon my ramblings - caffeine hasn't kicked in yet...) Hi all, I've been off the air for quite awhile, but yesterday (Sunday) I followed the ol' New Year's resolution and got back on. I'd just finished rebuilding a homebrew antenna for 20m and figured it needed a trial run, plus I wanted to try the qrp rig (my first - an MFJ 9020) I got for Christmas. Anyway, I was tuning around 20m, heard a fellow Californian and worked him. Got a 559, which I felt was a good start for 600 miles. Not spectacular, but at least it proved things were working. Then I heard a call from 8-land, figured what the heck, I'll bite. Well I almost fell over when he came back to me! Got his info (he was in West Virginia, gave me a 569) and just as I was sending mine, the band fell out from under me. AAARRRRGH!!!! So much for that QSL. I guess that qrp WAS is a little further away than I thought. Still nice to know that my 4 watts got me from San Diego to West Virginia, though. Not new to most of you, but fun for me! Bottom line - I'm definitely hooked on qrp. One final note - my original elmer (a dedicated kilowatter) heard me by chance when I started my QSO with 8-land. When he found out I was operating qrp he was a bit shocked, and definitely impressed. So I even did a bit of qrp evangelism for the week. :) So how was your weekend? 73, Joe KD6PRD jgervais@ucsd.edu Next project - homebrew rigs.

Their phone number is disconnected, but a letter sent by N7RVD revealed that they are still selling these kits for $49. There was also this recent post from INFO-MAC: If you're looking for a good expensive keyer, I recommend the CMOS Super Keyer II (93 ARRL Handbook, pp 29-6 through 11). Kits are available from Idiom Press, Box 583 Deerfield, IL 60015, for $45 + $3 shipping. I'm not connected to Idiom Press, but I've built their kit and installed it permanently in my HW-9. The board is about 1.5 X 2.5 inches with the battery, 4 push-button switches and a pot mounted off board. The push buttons control the memories and some commands. Sending speed may be changed via the pot, memory commands or the paddles. The keyer has numerous commands that are input via the paddles and may be included in memory messages. A very versatile keyer for little $$. (The SA-5010 was $99 new.) 73, Bob, KU7G So send 'em you money -- this is a good deal and easy to build too! ------------------------------------------------------------------- and....................... ------------------------------------------------------------------- I received my Super Cmos Keyer II kit Saturday from KB6NQ, and I have it built and working. The kit costs $25, and includes the pcboard, programmed chip, all board parts, 4 switches, 100K pot and a speaker. You must supply the cabinet and connectors. My kit did have a couple of mistakes in the resistors provided. I replaced them from my stock on hand, but it would be nice if you got the correct parts.. But a minor item. I chose to replace the switches provided with ones that I had on hand, they were much easier to mount, as they just needed a round hole, while the ones provided need a rectangular one. The speaker that I got did not work, maybe I fried it when I soldered the leads on, but it was only 1" in diameter and not high quality at all. I replaced it with a 2" radio shack 8 ohm speaker, which works fine. The kit only takes about an hour to build. But by the time you mount it in your case and dress the leads, plan on an evening. When you finish and have it working, then the fun begins. The keyer is fantastic. Are you ready for the features? Here they are: Iambic keyer with selectable dot and dash memories Four messages totaling up to 220 characters Character and real time message loading Timed pauses within messages. Messages that can call other messages and contain operational commands Message loop capability for continuous play Message break in to allow for paddle inserted text Input queue to store multiple message activation Contest Serial numbering (001-9999) Digital and linear analog speed control (6-60 WPM, Messages up to 990) Adjustable weighting (dot/dash ratio) of 25-75% A built in adjustable sidetone monitor A transmitter keydown (tune) function Handkey mode Compensation for transmitter induced keying distortion Selectable automatic character spacing Keyer status inquiry functions Ultra low power consumption for battery operation If you want more information, refer to any recent ARRL handbook. The 93 edition has the article on page 29-6. I recommend the KB6NQ kit. For $25, you can't beat the price. Idiom Press sells the same kit for $45. I am not affiliated in any way with KB6NQ, just providing information to fellow qrpers. 72, Doug, Oh, by the way, if you haven't ordered the set of schematics from Chuck, do so. They are an excellent edition to your library. I got mine Saturday.

I'd say a general rule of thumb is if you don't have them made by now, you won't have any. You could start calling a few places but I'll bet you will find most everything already taken. If you check your Ohio map you will see some towns/cities nearby - you might be more productive to check there. As for me, I am fortunate. I have a brother-in-law who lives a bit away from Dayton, but close enough to be realistic to drive back and forth. So it isn't that hard for me to deal with a place to stay. They generally like to have us visit....... :-) I am not sure at this point if I am going, won't know until probably a couple weeks before the fact. I have a few few things on my current electronic "hit list" that I'd like to scrounge for..... monochrome CCD video camera, must be sensitive to IR in the 700 to 1000 nm wavelength range, must not require multiple mortgages on the house I haven't bought yet. :-) freq. counter, doesn't need to go over, say 150 megahertz. ......and so forth. The only bad experience I have had out of several` visits to the Dayton Hamfest was the last one I went to and got heavily, and I mean HEAVILY rained on.....and it was cold, too. Made for a less than pleasant day. Word to the wise - watch the weather channel closely, and be prepared with a poncho or something similar if it looks like it might rain. A poncho keep both hands free, unlike an umbrella, and can also keep HT's and associated gear dry if you belt-pack 'em. I get the feeling that people who have never been to Dayton before are unaware of what a monster hamfest it is and just how many hams will be there. It is HUGE, and THOUSANDS or hams will be there - and I don't just mean 1000 or 2000, either. Would it be unrealistic to say 40,000 or 50,000 will attend? Is that too low? :-) Hmmm.....maybe a meeting of the internet QRP mailing list??????

The Gary Breed was from an article in QST and in the Handbook. Pat Buns had done some redesigning to get some more bandwidth from the rig. He used 12MHZ crystals instead of 4 MHZ and changed the needed component values around. I was never as happy with this version as the 20 meter version from A&A (original design). I ordered matched crystals and the other parts I needed and started on the receiver.. got that going and it works really well.. then redid the transmitter.. had a real weird problem with the 2 adjustable coils after the oscillator changing the frequency and messing up the SWR.. found the only difference was the coils in the TX were same value but higher Q. there was a 5 pf cap inbetween them.. changed it to a NPO 86 or so and the thing works great now. I find this rig works very well when the band is real noisey or crowded, really seems to be able to seperate out the signals well without needing extra audio filtering. I also find that the TX works well and seems to bring very good results. By the way.. boy is it snowing.. have about 5 inches so far.. had no electricity last night .. not real good when you heat with electricity.. the trees are so heavy that the larger branches are in the road.. my bug catcher antenna really cleared off a bunch of trees on the way into work.

Resistors, in bulk....caps, in bulk....values like .001 thru .1uf of the disc type...50-100 volt rated... .047 (473) being a good universal fit most everything value... values like 4.7 pf thru 820 pf, disc, NPO is best, maybe some N750's etc all being 100v thru 250volt would be best... Electrolytics (or tantalums <---cost more) of the 1uf thru 1000uf sizes, 15vdc to 35vdc ones being best, while the 6 and 10vdc ones end up being orphaned...not too many ckts run on such a low voltage! and for resistors, 1/8 thru 1/4 watt, 100ohms thru 100k if not higher... trim caps, trim pots, small tuning caps with usable length shafts and an easy way to mount them...regular pots (WITH the nuts!) Knobs---ones that fit the shafts of the above....and a hex key wrench to fit the set screw of them! Nuts, bolts star-washers spacers (metal and non metal) PC boards single and double sided Transistors like 2N3904 2N2222 or their generic subs.... Lots of various colour wire...LOTS of it! plugs, sockets...but stay away from BNC...they wear out fast. I use PL-259 and SO-234 or RCA the most. === A good source of yummy parts would be from a roasted TV or VCR...which now- a days, costs too much to be repairs, so most people give em flying lessons. Lots of still good parts in them...and you can test each one prior to re-use to make sure it wasn't the part that caused the trouble. ( ohm meter and capacitor tester/reader is all ya need ) Leave the parts ON the board, to let you ID what kind of ckt they were in and for lead ID....usually marked ON the board... Pick the board for parts AS yopu need them....don't strip it clean...you'll lose the ID I just mentioned. Just remove the board from the 'chassie' and discard the non-electronic section to save on storage space. Be XXX carful about the pix tube....DO NOT mess with the wire that leads up to the side of the tube...as the tube stores the high voltage (up to 25,000v) for very long periods after the set is shut off! Use a PLASTIC rod to pry the wire off (use force...don't worry about breaking the wire or the HV coil it leads to) the tube...and don't touch the now exposed belly button as you extract the ckt board. VCR's and fried sterios ( portable or not) have no such HIGH voltage, so you can just start hacking. Study as you go...you learn how the stuff is made as you go along.... and in general , get to see how it works. Zapped computers have very little you can reuse for RADIO......just a few capacitos, resistors....may a few regulators, diodes.....NOT worth paying over a couple dollars for... If you head off to a ham fest.....you'll wish you had about $70.oo on you I generally spend over $20...and never yet spent over $70....and I stock up like Byrd going to the S. Pole too. Go thru 2 times: 1st time to spot where stuff is, and to see if a 2nd table has same thing for less cost. Waiting also until JUST before closing, some vendors will GIVE you the stuff just so they don't have to take it all the way back home! Get somthing to eat so you won't be 1/2 starving while trying to concentrate on what you want to get... Good luck!

My other reply went only to you...could ya bounce it to the Mail group please? The one about parts pile building? --------- AM is not as popular as SSB is... It needs more power to get the same effective range-thru-noise. However, I have heard 20 watt stations and even a 5 watt station on 3885kc in the early and mid-mornings. QRP 'technically' is 5 watts max RF output and not over 10watts DC input even if that means less than 5 watts out put ( there are ckts that are like that). No matter what mode. AM, being now-a-days, (when run properly) the Caddilac or Rolls Royce of the voice modes, you go for nice clear sound...not try to have punch or use it to squeak thru a lot of noise. Some guys do...and it's close to sounding like SSB with yer BFO off! For range and all that, SSB is the voice mode best to use. CW tho, is best of all...from a miles per watt standpoint. If you do run AM....you will want a MONSTER antenna. You may find, that the VHF bands are better suited for QRP AM.... because, beam antennas can be used, and you can 'borrow' technology from the Aviation radios.....who still run AM on the 125mc band. -- Randy KA1UNW If you get a shock while servicing your equipment, "Works for me!" randy@192.153.4.200 DON'T JUMP! -Pete Keyes You might break an expensive tube!

How much should I be looking to spend? If you're in a hurry, DigiKey has bulk resistor assortments (which I used to start my junk box); their RS-125 is a set of 5 each of the 73 5% standard resistors (1/4W) between 1.0 and 1.0M, for $14.95; their RS-225 is the 72 5% standard values from 1.1 to 910K, $14.95. They also have equivalent 1/2W assortments (RS-150/250, $16.95). These are all carbon film. Probably you can do much better than that at hamfests (4c per resistor), but at least you'll know where they came from :-). That approach also has the advantage of making sure that you *do* have any value that gets called out in a schematic, whereas hamfest/mail order packets have a tendancy to be either "whatever random resistors were overstocked somewhere" or "the ones that crop up most often in the schematics I've built so far". Of course, once you start out with 5 of everything, you'll find that you *do* want an absolutely full drawer of 1K resistors but may never actually get around to using those 1.2 ohm resistors ... Mouser also has a carbon composition assortment you'd probably want (much less complete, but has the really popular values, well most of them). DigiKey also has capacitor assortments, but capacitors are somewhat trickier to stock up on -- you need *so* many different *types*, and capacitor manufacturers are somewhat lackadaisical about standard values, especially mica capacitors. I got a few of DigiKey's assortments (popular values, not complete sets) and have mostly relied on random purchases to fill up my junk box. To stock up on toroid cores, I took out W1FB's QRP Notebook and QRP Handbook, figured out the most popular cores, and got a bunch of those. Unfortunately, my junkbox is at home so I can't just come up with the answer I found; as I recall, though, I think it's mostly T50 and T68 in #2 and #6 material (T30 as well, I think), and three sizes of two types of ferrite that I can't recall. (I've also got a whole bunch of T44-7 cores due to a repeated mixup by Amidon.) A *long* time ago I used to gut TVs &c for parts, but I now lack the patience (and modern TVs lack the recyclable parts :-).

I know of one person who removed R24 (100 ohm) completely. That gave more audio to the speaker." I also order a center-detent pot for the RIT control. I haven't received it yet so I can't tell you what it cost.

If the markings are the manufacteur's standard part #'s, you will need to know who the manufacteur is and have their catalog. However, sometimes these mark- ings are house part #'s, where a manufacteur marks the device with a customer #. Now you need to find out who the customer was and get a copy of the spec- ifications.

Specifically, the 42IF128 is for use at 10.7Mhz, has a primary that is tapped (about 1/3 up), has a capacitor accross the primary and a primary to secondary turns ratio of 8:1. Other 42IF series units are vary by physical size, frequency, tap point, turns ratio, pin out etc. So you see it is important to get the specific specifications.

What I did, was to get one unknown xformer, and send my signal generator thru it...fed in on the low z /tickler coil side, and watch the Hi Z side with a scope....sweep the generator by hand and look for the peak in signal. Such coils being adjustable, the markings on the generator's dial are accurate enough to tell you the freq. Connect to the scope by the shortest possible leads, and NOT with coax. Also, I found it helps if a series resistor of like 470 ohms is used between the sig. gen and the small coil to allow the peak to be more pronounced...not loaded down by the gen's low Z. -- Randy KA1UNW If you get a shock while servicing your equipment, "Works for me!" randy@192.153.4.200 DON'T JUMP! -Pete Keyes You might break an expensive tube!

May want to run it on 80 Also, the pinout the guy gave me was the same as the SBL-1. Can anyone confirm this?
