[TowerTalk] Antenna switch noise

[Robert Shohet]

> Hi Chris,

> I have experienced this twice with the Ameritron RCS 4 - both times it was
> when the switch was malfunctioning either as a result of a condensation
> buildup or the after effects of a nearby lightning strike.
>
> Both times I was unable to fix the switch and had to replace it.  In my
> experience, it is rare that either the switch or the outdoor relay box go,
> usually they both go, seems like whatever affects one adversely has the
same
> effect on the other.

> I hope that you have better luck.
