[Premium-Rx] WJ-8617/8618 IF, SSB, FE options for sale

[Terry O'Laughlin]

I am looking for a DRD option card or the option card for controlling the 
WJ-9073 remote preselector for the WJ-8617B(S1) or WJ-8618B(S1).


Dual IF parts for any B(S1) version of these radios, all with documentation.
(installation by flipping a switch on the motherboard - details here: 
http://watkins-johnson.terryo.org/Graphics/WJ%208617(S1)%20or%208618(S1)%20option%20switches.jpg)

Note that dual IF boards cannot be intermingled with single IF plug-ins 
without modifying the single IF plug-ins.

100/300 kHz IF filter board and demodulator with 100/300 button for front 
panel.  Has separate ceramic IF filters for each bandwidth.  Tested, 
working.  $275 for set.

6.4/10 kHz IF filter board with 6.4/10 button for front panel.  No demod 
board.  Has separate ceramic IF filters for each bandwidth.  Tested, 
working.  $150.

1000/2000 kHz IF filter board with 1000/2000 button for front panel.  No 
demod board.  Has separate ceramic IF filters for each bandwidth.  Tested, 
working.  $100.

20/50 kHz demod board.  Tested, working. $100

400/600 kHz demod board.  Tested, working.  $60

Some notes on the IF and demod boards.  The IF boards and the demod boards 
each have the same foil patterns.  A small number of components and the 
filters can be changed to adapt boards to different bandwidths.  The full 
list of components needed to effect the desired change are on the 
documentation for the boards.  The demod boards are primarily FM 
discriminators.  A wider bandwidth demod board will work acceptably well 
with a slightly narrower IF filter board (i.e, a 6.4/10 IF with a 20/50 demod).


SSB option card for WJ-8617B or later, WJ-8618B or later with SSB button 
for front panel.  (may fit A version but I don't have documentation to know 
for sure).  Adds USB and LSB option with a third conversion stage to 10.7 
MHz and separate asymmetrical 3.2 kHz USB and LSB ceramic 
filters.  Requires CW or VBFO option (I might be able to find one if you 
need it).  Tested, working, with manual $500


FE option card for WJ-8617B or later, WJ-8618B or later.  Highly desirable 
option extends coverage to 1100 MHz.  Consists of two boards and 
cables.  Plug-in, connect cables and flip switch on motherboard to install 
(see link above).  Tested, working with manual.  $900


Parts like these are rarely available for sale.  If you'd like to see them, 
I can bring any of them to the MARA swapmeet this Sunday at the Mandt 
Auditorium in Stoughton, WI. http://www.qsl.net/mara/swap05/swap05.html
