[Premium-Rx] FS: WJ receiver

[Terry O']

I have a WJ receiver for sale that is classified and I cannot describe 
on the internet due to ITAR regulations.  But, as there are 4 de-mil 
units for sale on eBay right now, I thought I'd post mine:

If you need more, there is also a data sheet for it on the Kongsford site.

My radio is complete with operating cables and a full copy of the 
service manual for both parts and options.  The DCU is in very good to 
fine condition.  The TSU is in good to very good cosmetic condition.  
The yellow plasma display is crisp and bright.  It has has the 12.4 GHz 
FE and SM options.  I do not have the fiber optic link but the twisted 
pair "backup" link works fine if the DCU and TSU are in the same building.

I bought it with a blown tantalum cap in the DCU on the back of the 
display board, which I fixed.  It ran beautifully for a couple years.  
It went into storage for over a year after I moved.  When I pulled it 
out for a buyer last year, it was not working.  So I canceled the sale.

Since then I found a blown tantalum in the TSU on the backplane next to 
two other caps replaced by someone else.  All three blown caps were on 
the -18VDC bus.  So I replaced all 27 tantalum caps on the backplane.  
The TSU still has a short on the -18 VDC bus, in all likelihood a 
tantalum capacitor I haven't found yet.  The DCU operates perfectly, but 
will not boot when connected to the TSU because the TSU trips the 
overload protection on the -18 VDC bus in the DCU.  If I had the time, 
I'd replace every tantalum capacitor in both units.  They are obviously 
at or near the end of their life cycle (a common occurrence for early 
tantalums).

My research into the history of  these radios and their manufacturers is 
taking so much time I know I'll never get to all the units I own, so I'm 
starting to sell them off.  This one goes first.  It is one of the most 
exotic radios I will ever own.  Just check the specs.  More frequency 
coverage, bandwidths and spectrum display than you'll find in any other 
radio ever made.  There are not many of these around.  One source told 
me when they were new a non-ITAR country offered a $1 million dollar 
bounty for delivery, no questions asked.  Original sale price was over 
$200,000.

My asking price is $4,000 for the TSU, DCU, all cables and full 
operating and service manual for all parts (DCU, TSU and the options).  
Price includes proper packing and shipping to anywhere in the 
continental United States.  I will not ship anywhere else.  This radio 
is for sale only to US buyers or residents of ITAR countries with a 
continental US shipping address.  The radio is sold as-is.

DRS informs me I cannot send photographs or technical specifications by 
electronic means.  My research depends on the cooperation of DRS and its 
employees.  Please don't bother to ask for an exception.
