[Premium-Rx] Watkins Johnson WJ-8716 Battery

[watkins-johnson at terryo.org]

There are two versions of the A3 and A4 cards in those receivers.  The
processor and memory move from one card to the other as the version
changed.

> Success ----- maybe !
> Talk about a can of worms. I pulled every card one by one and found a
> location for the battery (BT1)
> on the Synthesizer Interface Card ( 794275-1 ). No battery installed, of
> course but there is hope.
> Interestingly, that card is not even shown in two different WJ-8716/18
> manuals that I possess. In my manual(s) the battery is shown on the Manual
> Tuning Up/Down Counter card. There is absolutely no place on that card for
> a
> battery nor is it even referenced. Very confusing unless one is into tons
> of
> mods and revisions for these receivers. Nevertheless, I will head out
> tomorrow and pick up the necessary items to initiate an off-card battery
> installation and see what happens.
> I want to take a minute to thank all of the many responders that tried
> their
> best to help me out in my time of need. Special thanks to Kurt, Mark, and
> Al
> for their many emails and ideas. Your gracious assistance  was certainly
> appreciated and my very best to all.
