[Premium-Rx] FS: Assorted Watkins-Johnson gear

[Terry O'Laughlin]

I'm culling my Watkins-Johnson collection down and will be taking the 
following items to the MARA Fest in Stoughton, WI this Sunday, April 17th 
http://www.qsl.net/mara/swapmap2.html

WJ-8888/LFC - low frequency convertor, input is 0-1 MHz output is 2-3 MHz, 
automatic antenna switching between HF and LF, LF inputs for 50 and 600 
ohms, originally designed for the quad-8 but will work with any HF 
receiver, 1 rack unit high, tested and working but original specifications 
are unknown, $450

WJ-232 - "tunable preslector" - actually a 2-30 MHz single band HF receiver 
with everything but the detector stage, has 60 MHz first IF, 10 MHz second 
IF with 5 kHz crystal filter, 25 kHz final IF and output, perfect for a 
Tayloe detector and DSP based project, very hot receiver and very stable, 
1/2 rack width, 2 rack units high, metal tape tuning dial with provisions 
for external counter and digital frequency control with a unit like the 
DRO-311 (below), working with partial manual $225

WJ-9080A convertor - 30-1000 MHz single band convertor with 160 MHz and 
21.4 MHz IF and SDU output,.  first IF is around 2 GHz, stable versatile 
unit,  makes a great front end for the RF Space SDR-14 receiver, metal tape 
tuning dial with provisions for external counter and digital frequency 
control with a unit like the DRO-311 (below), working $300

DRO-311 frequency display - for displaying and digitally stabilizing the 
frequency of up to four receivers, current IF offset is set to 10 MHz for 
the 565 receiver series, each receiver input can be individually set to its 
own IF offset, working $275

DMS-109 demodulator - 5-1000 kHz USB/LSB demodulator, digital readout, can 
be tuned to 25 kHz and works well with the WJ-232 convertor listed above, 
working  $200

TF-105 tape to IF - 21.4 MHz spectrum display with tape to IF convertor, 
for conversion of recorded spectral activity back to RF for detection 
analysis, working $175

FE-103 convertor - 10-30 MHz input, 21.4 MHz output, metal tape tuning 
dial, working $125

AP-101 audio panel - speaker panel with switch to select from three audio 
inputs, microphone and test oscillator circuits and provisions to couple to 
three different transmitters, only piece of WJ gear I have seen having 
anything to do with transmitters (other than jamming), working $250

I'll be at the big booth on the west end of the hall.  I'm sorry, but I 
won't have time to respond to requests for more information or pictures 
before the swapmeet.
