[R-390] R390A Antenna Relay

[Tisha Hayes]

The antenna relay contacts and fingers can end up looking really blackened
and ratty. I think they are silver plated, the oxide really does not affect
the performance of the relay but you can clean them if you want to. Just be
careful as you do not want the spring fingers to lose their temper
(springiness).

I used an ammonia based metal polish for silver and brass (Simichrome). You
could use a very soft bristled toothbrush to apply it and polish it down. I
also use it on the brass gearing in the drive-trans of radios (as if anyone
will ever see how pretty they look).
