I Heard the interview of Alan at WRMI in Okechobee Fl probably when he picked that TX up.  Essentially one broadcaster glad to support a fellow broadcaster...I was glad to stumble on the broadcast at the right time. 

Thanks,

This was on my local NCDXCC list:

Before I haul these over to the local scrap yard I thought I would see
if anyone needed one of these for a QRP project.

All have been tested and work fine. The transformers have 105V inputs
(no 220 V primaries). The choke is 60 Hy at .6 amps.

The 6660 V transformer weighs 132 pounds ($14).

The 7500 CT transformer weighs 106 pounds ($10).

The 60 Hy choke weighs 162 pounds ($17).

These are for pickup only in Simpsonville, SC.

Thanks and 73,

that's a hell of a 60 Hy. mod reactor!

hope they don't get scrapped!

The plate iron seems like 1/2 amp CCS judging by the weight.

I have pix of these if anybody is interested.  Also, there might be a way to deliver them to Dayton. I normally go there, but can't this year, but my 4 buddies that have gone every year forever, I can finagle into taking them up there.  They set up to sell vintage gear and odds and ends, so you would be able to find them at their tent farm.

Message-ID: <102e4711-cf5c-f4d6-bdc1-ba1b0ac6ab58@gmail.com>


Yaesu FT-757GX, HF Transceiver and Associated Items For Sale.
Also linear amp interface box, hand mic, mic adapter,
programing software/hardware, and manuals For Sale :
.

.
Yaesu FT-757 GX, HF Transceiver:

The Yaesu FT-757GX is an HF transceiver covering 160 to 10
meters with ten memories. The general coverage receiver
tunes from 500 kHz to 30 MHz. Power is 100 watts CW, SSB,
FM and 25 watts AM. The FT-757GX features IF Shift,
Electronic Keyer, Squelch and Noise Blanker.

The top panel has CW adjustments. The rear panel has
numerous input and output jacks. It requires 13.8 VDC
at 19 Amps.

Features:
160-10 meters
IF Shift
Keyer w/Semi/Full Break-in CW
Dual VFOs
Noise Blanker
100 Watts Output
General coverage receive
Speech Compressor

It should be noted that this is not the high quality rigs
I normally sell, but an average transceiver, but the price
reflects this fact.  It does have dual VFOs, WARC Bands,
and memories, as well as an internal keyer.

Hand mic, power cord, and paper work included for $250.
.

.
Yaesu XF-8.2M-601 Crystal Filter:

The XF-8.2M-601 is used in the 8.2 MHz IF of many
Yaesu transceivers, including the FT-102, FT-747,
FT-757, FT-767, and possibly the FT-1000 series.
I was told it would work in the FT-1000 but have
not been able to confirm that, so please check
your manual.

The 600 hz bandwidth is ideal for CW, but it is
also great for RTTY and other digital modes,
including FT-8, PSK-31, etc.

This one works fine. It looks fine also, as if
that matters for an internal filter. It is a
"solder in" filter. Only $70.
.

.
Cable for computer control for Yaesu:

This cable was used on a Yaesu FT-757 GX, but I am
fairly certain that it can be used on other Yaesu
radios as well. The radio end has a small 3 pin, in
line, connector, which is of the same type as used
to plug into the various PC boards inside the radio.

The other end is a standard USB connector, which has
a USB to serial converter in the USB plug. To put it
another way, plug the 3 pin end into your radio, and
the other end into a USB connector on your computer,
and you should be good.

This one works fine. Only $20.
.

.
Buy all three of the above items (rig, CW filter, and
computer cable) for $325.
.

.
Yaesu FRB-757 Linear Amp T/R Relay Switch Box:

Many of the modern rigs are not capable of switching
the higher currents and voltages of the transmit
receive relays of some linear amplifiers. This small
box was made by Yaesu to remedy that situation.
Although it was made for the FT-757, it can be used
with almost any rig that needs a heavier relay to
switch the linear amp. It does not even need to be
a Yaesu rig.

This box needs 13 V DC (and has an RCA phono plug
for that purpose), and is connected to the rigs
linear amplifier relay output with another RCA phono
plug. The output of the box has both normally open
and normally closed contacts, both terminated in
RCA phono jacks. Contacts are rated at 600 VA AC,
150 W DC load, and will switch up to 250 volts and
up to 5 amps.
-
This one works fine and looks fine. Only $40.
.

.
Yaesu MH-1 B8, Hand Microphone:

The MH-1 is the standard hand mic used on most
modern Yaesu radios. It has a round 8 pin
connector on it. The mic itself has up, down,
and FST buttons on the top, to permit one to
change the frequency. On the back is a tone
switch to permit one to slightly alter the
frequency response of the mic.

If your Yaesu transceiver uses a round 8 pin
connector, this mic should work for you.

This one works fine, and looks fine as well.
Only $35.
.

.
Microphone adapter:

This adapter will adapt any mic wired with the
Kenwood 4 pin connector, and convert it to a
Yaesu round 8 pin connector.

Works fine; looks fine. $20
.

.
RT Systems ADMS-1802 Software/hardware:

The ADMS-1802 consists of a hardware cable, plus
a software CD, plus instructions to program a Yaesu
FT-1802.

These days the rigs have so many memories plus other
features, that it is almost impossible to program them
manually. The ADMS-1802 takes care of this problem
for the Yaesu FT-1802.

This unit appears that it might be new. Everything is
included -- Software CD, Cable, and instructions. Also
included is the serial number to make the software work.

This retails for $48.95. Buy this one for only $30.
.

.
Original Yaesu Manuals:

These are the manuals only. All are originals, and not copies.
Most are in close to new condition.

FNB-9,10,11,12 Battery packs, $2
FT-720 R, 2 meter mobile, $8
FT-890, HF Transceiver, $15
FT-1802 M, 2 meter mobile, $12

Subject: [AMRadio] Heath RX1 Mohawk info

Message-ID: <379873055.6527640.1518468847966@mail.yahoo.com>

After around 20 years of use, I put my Mohawk on the bench as it was getting a bit anemic.  This RX was  rescued as it was getting put into the trunk of a car by a man who's dad built it in the '50's and just listened on it, never getting a ticket.  The dad passed on and the son didn't want it.  I did go through it way back then, finding bad filters and coupling caps, cleaning up solder joints and doing a complete alignment, and the only failure I have had since then is the 6BJ7 detector tube, one filament went out of the 3 in the envelope.  Of course it was the detector section, not the AVC or ANL where I might have skipped it for a while before removing it from the bottom of the pile of gear on top of it and removing all the screws. With that said, I found an issue with 80 meters that I neglected way back when, but became evident that something was wrong on 80 compared to the other bands.  I did find the addendum for the prebuilt front end, but it doesn't show a complete schematic either, just a reprint of the RX1 manuals version.  I found an 82pf across the 80 meter antenna coil, which made the coil tuning mushy and the ant. trimmer not very effective.  When I removed it, sensitivity went up greatly, and the ant trim did it's peaking job like it was supposed to.  Does anybody know if there is supposed to be a cap across the 80 meter antenna coil, and also across the 40 right next to it?  The 40 meter cap is a 100pf unit, with color dots, while the one on 80 is the more modern with writing and the coded 820 for 82 and no zeroes. If it is supposed to be there, is is an 82PF? The parts list for the front end does not show these caps listed, the cap list is rather short, at first thinking they listed only the parts drawn on the addendum, but they do list all the coils, even though most are not shown. Also, if anybody has any suggestion on why the converter band has poor sens and breaks into oscillation,  that would help too.  15, 11, 10, no problem, with factory spec sens and no instability,  but the convertor band is a mess.  I was checking the tubes, and put one of the 6CS6's in the tester and turned it on, it got so bright at the bottom, thought I had left the filament in 12.6.  I looked closer, and where the filament goes into the cathode, a bunch of the coated wire was in a big knot right at the bottom of the tube and lit up like a light bulb.  It is a Raytheon 1958, and checked just fine too.

Hi Charlie,

Funny that the article says that the HW2026 "met spec" but was still
recalled.

I happened upon a large number of the recalled 2026 boards in early 1980's.
I first found the receiver boards, I think, in the Milwaukee Wisconsin
Heathkit store. I did some digging and found that Heath had split up the
recalled kits and sent different boards to each time zone. I think it was
the Eastern zone stores got the transmitter boards, Central zone got the
receivers, Mountain zone got the synthesizers and the West coast got the
amplifiers from the recalled radios.

I thought that I could make something useful out of the boards and bought
all that I could find by calling the Heathkit stores across the country. I
ended up with several hundred of each of the boards.
I put together a couple of the radios and found that there was no way to
make a useable radio with what Heath had designed.

The synthesizer scheme was all wrong. They divided the synthesizer signals
down and mixed it with a 1 MHz signal as I remember. It had mixing products
all over the place on both transmit and receive. The products were too close
together to filter out at the frequencies they were operated at.
I don't recall what their original spec was but it was unusable.
Just looking at the mixing scheme tells you it would be full of trash.
They did it right on the HW 2036 replacement.

I have used some of the receiver boards for projects and they worked pretty
well with an external crystal oscillator for injection.
Those boards were complete receivers with audio amp and squelch.

The other boards are useful too.

I obtained most boards that were completely built and some where all the
parts and bare board were still in the package never built.

I still have lots of the built and unbuilt boards left if anyone is
interested. There were several dual gate FETs that were similar to the
famous 40673 dual gate fet.

The receiver in the 2036 was almost identical to the 2026.
