Well I don't think it's RF in my case. All rigs are well grounded
(including the Omni V with the Herc) and the Argo audio was distorted with
the processor on and power levels varied from 1 to 20 watts. The reports
were similar with the Ten-Tec hand mic and a D-104.
The rig was new and I was trying ALL the features. I tried the processor on
3 (I think) and then got very poor audio reports. Since I don't use the
processor on my other rigs I turned it off and moved on to trying other
features! As I mentioned previously, with the processor off the problem
went away.
