[Premium-Rx] WJ-8718 Card

[Bob Betts]

John:
Your question is of interest to me as well. Please keep us posted as to your findings. Meanwhile, I'll poke around in the mess I have here.
Do you know any of the history of the radio? Had someone performed some mods? Is it not working properly? What symptoms?
 
Just wondering, b/c Geoff Greer (a great guy, sadly now deceased) worked out some mods with me on an MFP to accept an after market encoder. I made some IC changes to that Bd. here, too. For the life of me I can't find what we did. I just wanted to compare the two PC Bds circuits 796029-xx vs. 791575-xx.

I'll start digging in the next few days...after I fire the librarian.

Good evening all -

I am desperately in search of a schematic or source of same for a particular
WJ-8718 circuit card. I cannot find any reference to this card in the
WJ-8716/8718 nor the URR-74 manuals.

It is part number 796029 without any dash number. It is located in the 1A6A1
slot and is the Manual Tuning Up/Down Counter board with the three ribbon
cable connections to the BFO switch, frequency readout, and manual tune
boards. According to my research, it appears that most units have a 791575
board installed in the 1A6A1 card slot. Interestingly, Terry O`s listing
shows the 796029-xx boards as synthesizer boards for the MPF series of
WJ-8718s.

This is not the case with my unit, however. I would truly appreciate any
info that can be provided or a source from which I can obtain a schematic
for this board. My deepest thanks  and very best to all.
