WJ-8969 IFC and TU0145 in a 2U rack frame. Tested with a simple Wavetek 
sig gen and found to receive over it's frequency range. In very nice 
condition. $2900 plus packing and shipping from 53132. Please contact 
Jim, dk at videoterm.com if you are interested.  Paper copies of the 
manuals for the IFC and TU will be included. The manuals are also 
available for download from my website.

WJ-8969 IFC controller/demodulator. Tested with both a TU0145 and TU0412 
and works fine with both. This sale is for the IFC only. The other items 
in the picture were used for testing the controller. Available for $1600 
plus packing and shipping from 53132. Please contact Jim, 
dk at videoterm.com if you are interested.  The manual for the IFC is 
available for download from my website.

Watkins-Johnson TU0412 4-12.4 GHz microwave tuner for the WJ-8969 
receiver, tested and receiving. Occasionally sends a 2nd LO unlocked 
warning to the IFC (which is not included, this sale is for the tuner 
section only).  $1200 plus packing and shipping from 53132. Please 
contact Jim, dk at videoterm.com if you are interested.

A very rare radio for sale. The Watkins-Johnson WJ-8969C was redesigned 
for some classified project(s) by the WJ San Jose Reconnaissance 
Division starting from the Gaithersburg designed WJ-8969. Tested with a 
simple Wavetek sig gen and found signs of life but periodically shows 
unlock conditions on the LOs and frequency entry is erratic. In very 
nice condition. $2900 plus packing and shipping from 53132. Please 
contact Jim, dk at videoterm.com if you are interested. This may be the 
only one of these radios in private hands. Given the nature of the 
radio, it is only available to a US buyer to be safely within ITAR 
guidelines. This radio is significantly different the the Gaithersburg 
WJ-8969 and it is unknown how much of the manual for that earlier 
version will be applicable to this radio.

A system from Dennis Karski's listening post that is now for sale in his 
estate. A Watkins-Johnson WJ-9548 multi-channel FDM demodulator and an 
AM-105-2 12 channel audio monitor. Dennis assembled this to 
simultaneously receive 12 USB Volmet weather and HF airplane channels. 
The demod with a small front end preamp picks all up 12 frequencies 
(programmable for any HF frequency and either USB or LSB) and AM-105 
allows you to toggle which ones go to a recorder or a speaker (or mute). 
Multiple signals can be monitored at the same time and the COR light 
will tell you which one is active. You could also monitor amateur band 
nets, beacons...

A renowed WJ engineer told me the WJ-9548, which was one of their first 
products to use the Motorola DSP56000 series of ICs, inspired the 
company to create the WJ-8711. He and another engineer were tuning 
around the HF bands with the WJ-9548 after a trade show and realized 
they could design an HF radio around similar circuitry. It took some 
lobbying to get management on board, but when an end user approached 
with suitable development funds, the WJ-8711 was born.

These two items with cabling for ready interconnection made by Dennis 
and the four parts units can be yours for $1800 plus packing and 
shipping. I fired up the demod and it appears to work, though the 
display is readable, the contrast is low. Four "sanitized" parts units 
are included from which a display can be repurposed. If you are 
interested, contact Jim via DK at videoterm.com.

Another item from the Karski estate sale. A Watkins-Johnson WJ-9472 
demodulator. This has the FSK/OOK module and will handle any mark tone, 
any space tone and a wide range of baud rates. I fired it up and it 
appears to work, though I didn't have any signals to feed. In near mint 
condition. I have a proof manual (edited by engineers and has their 
corrections and comments) and will scan it for the buyer. $850 plus 
packing and shipping from 53132.
------------

 From the Karski estate sale, an Astro-Link MTR-209 demodulator. It 
tunes 50-90 MHz and demodulates FM and BPSK. Other than that it is a 
mystery box to me. With his station and antennas dismantled, I didn't 
have access to a 70 MHz satellite IF to check it out in detail, but 
everything appears to operate as it should. Just $275 plus packing and 
shipping from 53132. Contact Jim via DK at videoterm.com

Dennis Karski's estate has a Watkins-Johnson WJ-1250 with all six 
plug-ins. 0.5-1 GHz, 1-2 GHz, 2-4 GHz, 4-8 GHz, 8-12.4 GHz and 12.5-18 
GHz. I tested the entire system and all the plug-ins. There is some key 
bounce on the mainframe, but relatively manageable. Three plug-ins lock 
onto any frequency, two plugins lock over most of their range. The 
12.4-18 GHz only locks up to about 13.5 GHz. These may be just alignment 
issues.  Shipping is available. Manuals for the mainframe and some 
plug-ins will be included.  Available for $4500 with all six RF heads 
plus packing and shipping.

Dennis Karski's estate has a Watkins-Johnson WJ-1204-1 microwave sweep 
generator. Tested and found to sweep a variety of ranges between 1 to 8 
GHz. There is some dark segments on the LEDs. Otherwise in good shape.  
Manuals are included.  Available for $3000 plus packing and shipping.

There is much more test equipment and really unusual stuff... You might 
want to make the trip for this once in a lifetime estate sale.
