[R-390] R-390 attacked by RF from old guy

[Frank Hughes]

OK, let's just hypothesize that someone that will remain nameless, but IS A
SENILE IDIOT, no, calm, very calm here...
managed to transmit into the receive interface of his prized R-390.

This particular R-390 is configured for break-in, so the signal input was
brief, for the duration of the R-390 antenna and audio relays grounding the
respective circuits.

The unit seems to still receive 3885, but the band has been in poor
condition here, owing to thunderstorms, etc, so I still don't know if it is
receiving as it should.

I'm thinking that I could just configure the 8640B and input the signal
into both R-390's (production and spare) and the spare R-390A, and see if
there are any significant differences in receive level and audio quality???
Or do I have drain bammage?
