Your problem is the LSB crystal in one or both the Rx and the Tx have
changed.

Also the crystal filters have changed.

In most cases they crystals will drift downward in frequency with age.

You need to have extensive test equipment,,,or you can wing it.

Try adjusting the tx LSB xtal only to match with the receiver. Play
around
between them both.

Have fun.

Hi Dan,

I was hoping that wasn't it. Don't know where to get crystals for it
that would be any better than what's already in it.

Have a 'scope, counter, RF generator and various meters, but am pretty
green with it all. Good experience though!

Thanks for your reply.



Its probably only a minor tweak. Nothing to buy.
Collect the documentation and go for it...nothing to lose and everything
to gain in this case.
