what would be a fair price for one in typical fair to good physical condition that works well electrically ?
is the echo on these as good as the echo in my 2018 xtreme mic ?
I have a Xtreme 2018 - a very decent mic. It is made by the same company that makes the OmegaForce and the DeltaForce radios - "RF Limited".
So, the quality of echo in the radio is as good - if not better - IMO.
I've never owned or used a DF radio, but I also own the OF and I thoroughly recommend it - impressive! It is the only radio (out of 12 radios) that I use every day on my base station w/a D104 TUP9...
