[TowerTalk] RCS4 Antenna Switch - Noise

[K0YR]

T/T,
This RCS4 has a built in power supply. No wall wort. When switching unit 
is brought in to the bench, there is no noise, only when placed at the 
tower. Noise goes away when power is off or in the #4 default position.
Just curious if anyone has experienced this before???
