I have an analog TenTec Argosy that I have thought about modifying to
cover the 17 and 12 meter bands. The 2 500 kHz bands for 29 mHz are
unused and I have considered drilling and blasting to add the 2 WARC bands
it doesn't cover.
Anyone ever tried this?

>------------------------------------
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!

Well gang, I will be on the road starting this Wednesday evening
and looking for some mobile contacts. I plan on operating QRP
SSB (not coordinated enough for CW), but depending on conditions
and how easy it is to get contacts, I may up the power a bit.
Frequencies will be the established QRP ones for SSB: 3985 on 80m,
and 14.285 on 20m. I have not at this time been able to get my
40m antenna to work correctly, but hope to do so before the trip.
Times will be from 0000 utc to about 0500 utc on Wednesday the 22,
and the morning and early afternoon of the 23rd. I will be driving
back on the 1st or 2nd of January, and will follow the above freqs..
Merry Christmas and Happy New Year to all.
72, Mark

Hi All,
I will be driving to Idaho for xmas in the early am of Wed,22 Dec.
Got the rig mounted in the "new" 4x4 yesterday. Also the ant. With
any luck I will be able to get things wired up and ready to play
today. Will have to hold the keyer under my leg. No time to make
anything to hold that.
So listen most all day for me on 40, around 7030 and 7050. Will
also check in with the county guys on 14055.
Happy days and cul...

Spider transceiver (DC receiver) .. crystal controlled the same
oscillator for both TX and Rec.. haven't studied the circuit.. but also
have a 624 kits VFO-2 that is for the same band.. how do I mate the 2
and come up with a VFO controlled transceiver.
question 2.. does the ARCI do something about reserving rooms anywhere

Priority: normal

E-MAIL REPLES TO ME ****** DIRECTLY ONLY ****** No List
Replies Please, as this is not directly pertinent to list.
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.

Comment: MEMO 1993/12/23 17:00
QRP Gang,
We are about to close up here until January. Happy holidays to
everyone from the Florida Space Coast. Don't forget the Michigan QRP
Club Contest. It is January 1-2, and the details are in QST, CQ and
the ARCI Quarterly. I understand from those who have participated in
the past that it is always a good one.
Also, the ARRL Straight Key Night is always fun on Dec 31-Jan 1st.
Straight keys and QRP - what a great combination :-)

Subject: Surface mount parts
Can anI am interested in building a tiny transmitter which was discussed
in the Homing In column of the May '93 issue of 73 Magazine...The
transmitter described uses surface mount components and is a little
larger than a postage stamp! The article explains that most of
the parts can be obtained from DigiKey... Unfortunately, they dont
tell you aabout the ordering requirements at DigiKey... The minimum
order for each component value is 200 components! That brings up the
cost from something like $10 worth of parts to something over $150!
(Granted , I could build LOTS of Tiny T's!) but I only need one...
Thus, my question.... Does anyone know where I can get Panasonic
surface mount, thick-film Series 0805 resistors and capacitors????
(a place which would let me buy just a few of each component value)
A friend of mine mentioned Dan's Parts and Kits or something like that
but I dont have any more info on them...anyone else??
Thanks a lot for any help!

Active Electronics carries baggies of surface mount resistors
and caps (qty 20 per bag if I recall). 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 <grin>). 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).

I was wondering what a good, simple and cheap design would be recommended
for 80 meters receive. My brother built me a QRP xmitter that is a very
simple design, and I wanted to make a matching receiver. Easily attainable
parts would be nice as well.....

December 26, 1993
Gang,
This is version 1.0 of the QRP Club List for this mailing group.
Everyone save a copy of it. The next time someone queries the
group for any information on clubs, send them this list. :-) If you
have any modifications to this, please post it. This way, we
can keep it current. I had started this list several times in
the past few months because of the number of queries, but never
got around to finishing it. Then along comes Richard Fisher, KI6SN,
and does a bunch that I didn't know about. This list is a consolidation
of both lists. His list appeared in the Jan '94 issue of World Radio.
Reproduced here with permission of World Radio. Enjoy.
These are in alphabetic order and do not represent any order of
importance - politically, economically, or socially. :-)

Subject: MAVTI-40 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 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. Price $40.00

Subject: RadioKit Kits
Gang,
Bob, WA4ZID in MS, asked about the 40M superhet xcvr. 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. Does or has
anyone else in this group seen such problems?

Subject: WAS NorCal Test
Gang,
Here is text reprinted from the last issue of the QRPp Journal of
the Northern California QRP Club, Volume 1, Number 3, December 1993.
------------------------------BOT-----------------------------------
NORCAL 40 WAS CONTEST
To encourage use of the NorCal 40 club project rig, Chuck Adams,
K5FO, is sponsoring a contest for NorCal 40 owners. 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. :-)

For what (little) it's worth: about 5 years ago, I got the QRP-20 kit from
RadioKit (which may or may not be the same as what they're selling now). 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.

Obviously, no one involved in QRP saw that before it went to
press. Well, I've been after you folks to write letters....

Read on....in the ARRL general class license manual...page 2-6,
table 2-3, Suggested US RTTY Operating Frequencies (kHz)....
3590 RTTY DX
3610-3630
7040 RTTY DX
7090-7100...
and more in other bands...
Guess my motto will be: Have VFO, will use it....let's go, 80M...
Now, I'm just a listener, tech+ in waiting. Judging from the QRN,
QRM, and AM stations I've heard on the 40 meter novice band just
getting any signal out is going to be a challenge :)

Well, I looked into this RTTY DX Calling Frequency stuff,
and here's what I found out.
7040 kHz has been the RTTY DX Calling Frequency for quite
a while. 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.
Looks like we're stuck with this one.
Happy Wintersports,

Kevin and Jim started it. :-)
Look at it this way. 7.055 to 7.100MHz - digital.
7.000 to 7.025MHz - extra class segment
7.025 to 7.055 - 7.040 is dead center!! Everybody and their brother
is gonna home in on this puppy. It's first come first served. I'm
trying to do my part with 0.95W to hold it, but I'm losing a lot lately.
Someone tell me. What the heck is at 6.995 or so. Sounds like AMTOR,
PAKTOR, or some digital stuff. Has MARS gone digital down there?
I never heard from anyone in the world what was at 7.050MHz either.
Look for me on 7.040MHz starting 0200Z tonite. QRT for five minutes
at 0355Z for Texas Lottery. :-) How about a impromptu New Years Day
QRP QSO gathering of this group during the MI QRP contest? I'll try
to dig up the rules. Look 'em up in the Dec QST '93 issue. Post your
call to this group, so we can look out for you and avoid you. :-)
Just kidding, that's what they do to me. :-) I have to go and look

I got it. I'll go qrp digital. Then I've got them both
covered !-) Now let's see, shouldn't be too hard to build a
fsk qrp rig, that VFO wants to drift (chirp?) anyway.....
Why don't we go 7030 like the Europeans? Then we're "just
above Extra" (or is that 'just a cut below the rest' :-)

All,
Just got my Christmas present in today. 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.

HI,
Well before I was into QRP had purchased what I was told was a really
small 40 meter qrp transceiver. 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.

All,
was in the Smokies for a short vacation with the family. 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. First time ever saw an
Argosy.. now I want one for mobile.

Yes, Army, Navy, and Air Force Mars (including CAP) have digital
only authorized frequencies in that area (PACKTOR and AMTOR are both
correct answers).
I am, however, unable to disclose exact frequencies, system types,
and other important and pertinant information... Sorry...

Subject: W1AAZ to K5FO QSO is history
Yes, that's right. 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.
Looking forward to working more of the group.
Happy New Year dit dit

Thanks to all who responded to my questions about RadioKi -
I decided to go ahead and order one of the 40 m. versions. I think
what finally made the sell was the size - if I can get a superhet rig
smaller than this it may have to be the1G radio tha{'s sold by
Dan's small parts.
I hope to be on 7.040, or so, before {he end of January.
Tnx to all.

You'll sure as heck never get mine! 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.

Reply-To: al838@cleveland.Freenet.Edu (Eric J. Grabowski)
I will be attending a training class in Chicago later this month
and was wondering if there are any ham-related stores in the
area that I could visit. I'm looking for places that sell parts,
surplus, used FM gear, etc.
Any leads would be appreciated!

Subject: NorCal January Meeting
The following is an account of the January meeting of the Northern California
QRP Club. 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. Have a neat day today! 72, doug

Subject: MI QRP contest
Hi all, I completed the electronics of my second nn1g mk-II over the holidays
this one on 40 meters. 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.

In the most recent 73 I saw an ad for an ssb/cw rig sold under

Howes ssb/cw mono/duo banders (those british designed kits).
Has anyone had any experience with them ? I am mainly interested

Happy New Year all,
Went to the Chatanooga Aquarium yesterday to meet a guy with a Yaesu 301
QRP rig.. worked the contest mobile on the way there and back. On the
way back I got brave and called CQ.. had to pull off the road and got a
string of about 7 in a row. Worked it with my Argonaut 509 and a Texas
bug catcher. Need a noise blanker on that rig.. I really enjoyed the
contest.. even worked 80 meters the night before.. .sounded like thunder
storms on the band and inside the rig.. made it real interesting..got to
use every filter I had ever built.
Worked only 41 stations.. but wasn't on that much.

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.

All,
Well I started on my 20 meter Radio Kit.
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.

(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?

Boy am I upset.. had my first bad experience with a ham company.
I purchased the Cmos superkeyer II from R&R associates. Had it working
and then put it away. took it out about 3 weeks later for a contest. The
keyer went crazy. I checked the circuit.. nothing wrong.. finally got
the chip out of my Idiom Press version and stuck it in the
circuit..worked fine.. seemed it was definetly the chip.
Wrote a long letter and sent the chip back to R&R. Dick had chip for a
long time. .got it back today.. he told me to send it back to Bud
Southard.. no address or anything.. told me to check for a bad soldering
joint.. also gave me the address of Innovative Electronics and told me
to deal with them .. because that is where he gets the chips from..
I bought the kit from R&R.. think they should have done something.
Anyone have a phone # for R&R or know who Bud Southard is.
I think this Dick, is definelty a real .....

This was the one that Doug Demaw re designed.
I may build one, it's got artwork (which you don't really need), but for
a club project, it might be kind of nice to make the p.c. board.
Cap Meters are nice to have.

All,
quick follow up on R&R associates and the Cmos Super Keyer II.
I got Dick Rathburns number and gave him a call. I re-explained
everything I had said in the letter. The guy has a mouth like a sewer
and sure doesn't want anything to do with any problems.. just told me it
wasn't his problem and I should send the chip to the author of the
original article. I explained I didn't buy the kit from the author, and
didn't even know him and felt the problem should be handled by the
company selling the kits. He didn't have anything nice to say and
continued to use short words.
Well, on the bright side, I have found all the other people I have dealt
with in this hobby to be the opposite.

Hi and Happy New Year again.
I had a really great ham experience (for me at least). I was up early
and got on 20 meters CW the other day. I got a guy from England. The guy
just felt like ragchewing. We had over an hour QSO. In part of the QSO
we ended up talking about Ten Tec.. he had one and had visited the
factory. I told him that I was looking for an Argosy.. he said he had a
friend in Georgia that might have one for sale.. He took my packet
address and sent me and E-Mail (2 days to get to me). He has also
already made plans for Dayton.. and may be coming to visit me, or we may
visit the factory together... Ham radio is great...sure good way to make
new friends.
Is anyone from this group going? What is the story on hotel
arrangements?.. i have never been to Dayton and I am seriously thinking
about committing to doing it. .sure would be nice to meet some fellow
QRP people.

There was some doubt expressed earlier on this list about whether the
CMOS Super Keyer II form Idiom Press was still available. 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. Tnx Chuck for your efforts....

Subject: Re: Dayton
hotel arrangements in Dayton for the hamfest?
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??????

Jeff, I am going.. If you are thinking about it, start trying for
Hotel reservations, now!!! At this point, you may have to accept

you do something with a resistor; either take it out or short it."
It apparently is that simple, the question being "which resistor?"

All,
Might have already sent this.. but in case.. here it is again:
took some time this break to work on a 40 meter Gary Breed QRP I had
built from the 624 Kits version. 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. Don't see too much snow here. .sure is pretty.

Good point.. But, there are cancellations.. I would ask to be put on a
"standby list" if nothing else. And, if you have any friends,
relatives, or old college roommates within a hundred miles of Dayton,
that is definitely the weekend to go visit!!!

Yes, last weekend in April can mean anything, weatherwise.. Don't
count on anything.. The funniest year that I remember was when
somebody brought in a truckload of GI surplus clothing.. Friday, the
Army coats were $3.00 each.. On Saturday, it rained a bit and cooled
down.. Price of an Army jacket was up to $15.00 by Sunday morning..
Whole fleamarket looked like refugee city.. So, the moral of this
story is: Bring your longjohns, rain gear, and suntan lotion.. You
are bound to use one of them!!

I would say you are close.. The last time that I heard the "paid
admission" number, it was in the 37,000 range. It's the largest
convention in the state of Ohio. Thank goodness, only every other one
is wearing an HT! Intermodulation conflaberation!!!
But, if you ain't never been there, you have missed one of the good
experiences associated with your ham license.. I will never miss
another one! I didn't make '92. Ruined my whole year.. Look for me
in the middle of the flea market.. Gold hat, Callsign badge, and my
IC-2AT.. Should be easy to spot.. 8-]]]..
How many more days to Dayton?

Is there such a thing as AM QRP?
If the power limit for CW is 5W and the limit for SSB is 10W
is the limit for AM 30W? It seems if you were going to eventually
build a phone rig it would be a logical step to goto AM B4 SSB.
But I have not seen any projects for it.
Why is that?

Oh my!
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! Have fun!

I goofed! 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.

[This message is converted from WPS-PLUS to ASCII]
Since we are talking about keyers, I thought you might be interested in
a kit from KANGA PRODUCTS. I built an earlier version and have been
quite pleased.
From their catalog:
"The Iambic Keyer
This compact unit is on a small PCB measuring just 2.5 inches square.
Several hundred have been built and [are] regularly heard on the air.
They may best be summarised by...
Very compact
Full iambic operation
Dot-Dash memories
Very low battery consumption
Negative and positive keying
Keying up to 50V @ 500mA
On board speed control."
Price is 16.95 pounds (PCB and instructions only, 7 pounds)
Shipping to the U.S. is 7 pounds.
They also sell a speed control kit which allows six pre-set speeds.
Useful, they say, to instantly switch to the speed you require. Also
useful for the instructor.
Price of the speed control kit is 3.95 pounds (PCB only, 2 pounds)

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 :-).

Subject: MFJ QRP rigs -- opinions/flames wanted
Howdy All,
I'm thinking of picking up a MFJ 90xx series QRP rig, and would
like to hear any users (or former users) opinions of the rigs,
especially stuff you *don't* like about them. They seem to have
a fairly large following, but that be a side effect of MFJ's name
recognition and advertising resources. Please send any comments
to me by direct e-mail and I'll summarize to the group.
Also, if you had to pick any one band to operate QRP on, what
would it be? Assume the antenna would have to be a simple dipole
(or shortened dipole) for an apartment-dweller -- my current state.
Thanks much and I look forward to your net.wisdom!
72/3,
Bill, KD6TOB

Read July, 1993 QST for a simple process using a simple photo copier
a.k.a. xerox. I have used this method several times and it works good
and is cheap and easy.

Bradley:
There's a simple law of "ham" nature that can help you figure up
the cost of attending ANY Hamfest vs. the cost of goodies bought there:
THE AMOUNT OF MONEY SPENT ON GOODIES IS:
a) ALWAYS GREATER THAN THE TOTAL COST OF GETTING THERE AND THE
COST OF STAYING THERE;
or
b) GREATER THAN 10% OF YOUR ANNUAL RENT OR MORTGAGE plus your
GOLF HANDICAP;
and
c) ALWAYS MORE THAN YOU CAN AFFORD TO SPEND.
This formula is guaranteed to work !

Well folks, here is the answer to increasing the audio output
from the MFJ rigs (earlier versions). This comes from Stan Kozlowitz
at MFJ as a result of a fax I sent to him.
"You can increase the audio by shorting out R27.
Also, R35 can be shorted out for a little more
volume. 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. When I called
MFJ I was also told that there were some other mods done to the
40 meter version for stability but that this did not affect the
30 meter version.

Ga, om
I've long been interested in the possibilities of of am qrp myself,
but I guess the general lack of interest in the modality prodeeds from
the assumption--probably true--that am wouldn't do too well at low power
levels except in unusual circumstances. So much noise, etc. I did qso
a guy on 75 one day who was using one of these super modulation techniques
and suggested that, if I wanted to fool with that kind of thing inexpensive-
ly, I should do so at a low power level. Running 150 % modulation at less
than five watts? Might be interesting. You might also end up with laryngitis
from yelling into an empty bag!

I bought my 30m MFJ rig back in August, from AES in Orlando. Mine came
with the center-detent RIT installed. Grover, do you mean to imply that
this pot is NOT what came on earlier versions, so that you are doing this
mod, along with the audio mod? My audio is pretty weak, too. I wonder if
I already have the newer version, and the audio is STILL weak?

Can IF transformers be identified from their external markings?
The local surplus parts store in town has a box full of what I
think are IF transformers. They are in a 10mm can very similar to
the 10.7 mhz IF transformers provided by Dan's kits. They have the
same pin arrangement and a capacitor on the bottom. The major difference
is the marking on the sides. The ones in question are marked with "T-15"
on one line with "TP" stamped just below. (Dan's re marked "42IF", "128")
How does one decode these markings?
Any help is appreciated.
73, Bruce

Yes.....but you will need a cross reference.
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. This is easier said than done.

The 42IF series is listed in the Mouser catalog. 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. (reference pg138 Mouser catalog #572).
You can have some fun by getting and by making some measurements and taking
it apart, you can determine it's specifications.
By the way the Mouser quantity 1 price is $.79

Those are all 'in-house' numbers....you'd need know WHO made them
(Usually 'Toko' is the main one...)
Then you'd need get their data sheets.
In otherwords, not easy to do.
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.
