PGXL/MARS with non flex radio

I don’t know why it wouldn’t Larry.

The PGXL simply increases the power output levels from the input it receives. As long as your non-flex radio is physically capable of transmitting on MARS frequencies then the PGXL should just pass it all through to your tuner and/or antenna. Am I understanding your question correctly?

Larry, What particular frequency are you trying to use and those of us who have the PGXL and who are on MARS can check it into a Dummy load and see if ours is doing the same thing, and of course as Mike said is your Radio is capable of using those frequencies it should work.
