[Premium-Rx] WJ 8618B-(S1) ISB card?

[stephous]

I just finished cleaning the new WJ 8618B-(S1). It's working quite well.
Thanks to all who provided information.

One thing to note: This radio overloads easily below 30 MHz. The front end
is fairly hot. It has the LFE option and some band pass elements are quite
different from the common (S1).

I would like to know more about the ISB card, p/n 796304-2. The USB and LSB
levels are fairly low. There are pots all over the board but I have no way
to know what I need to adjust. This card is not in my manuals. I took
pictures of the card for reference. Any technical information would be
appreciated. I can send pictures if you like.

Best Regards,
Steve Pappin
