[TenTec] SS last weekend

I would worry about stray RF in the shack.  If it is getting into your rig it is getting into you.

PS:  Get rid of the stray RF

Well, some parts of Orion are not sheilded:  the front panel board
(encoders, buttons, LEDs) and A7 board (ADCs, DACs, processors, memories,
mic amp, speaker amp, headphone amps,...). They are just hidden behind
the plastic front panel. Any common mode current on external cables
enters those boards (esp. front panel board) without much trouble.

RF circuits have much better protection.
