[Premium-Rx] Need Racal Preselector Board Schematic

[Gary Geissinger]

Gentlemen,

I have a Racal preselector board coming to me in the mail.  I am going to
make it into a stand-alone device for use with a WJ receiver with no
internal preselector, but I don't have the schematic.  Here is the info from
the seller:

There are 2 DB 9 connectors on it the labels are J5 & J4. It has 6 rf
connectors J1, J2, J6, J7, J8,and J9. there is also a 26 pin header labeled
J3. there are alot of relays mounted on the board it looks like this is some
type of filter board. There is a number on the back of the board 4300217-1
the number on the front is Assy-4100433-501 above that is 23386 there is a
stock number for the 4100433-501 number 

Does anyone out there have a schematic for this one?  A picture is available
from an older Ebay listing:
http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=3009960214&category=4673

Given enough time, I can probably trace it out, but a printed schematic
would sure be a labor saver!

Thanks,

Gary WA0SPM
