It's the audio shaping. Adjusted the mike gain and processor for best
results. Tried both mikes. Got a pure tone and difference
disappeared. The Omni has more base. On further review, I sort of wished
I had bought the 200 watt model, but if you can use the internal tuner,
it's worth the difference in convenience.
If I really need to make the contact, I'll fire up the TR4.
