[TenTec] Orion RF issue

[Martin AA6E]

Aha. Well, then there might be something resonant at 80 M that is 
producing a high voltage at the rig.

You could try disconnecting everything from the rig, except the antenna 
coax.  (Grounds, mic cords, etc.)  That would still leave a possible 
common mode current coming in over the DC leads.  You could try using a 
storage battery or maybe easier, to make a choke for the DC leads by 
making 8-10 turns around a ferrite toroid.
