It was american Looking Glass..thanks.
MARS would make perfect sense.
I kept thinking it sounded like something in between a regular Ham Net and something sort of military. I kept lowering gain and changing sample rates to make sure it was not a Ham image. That has caught me a couple times with my SDR logging pirates when it gets in a funky state and I am logging SW broadcast images.
I heard twice "Unable to transmit digital on this frequency". Another station said send slower which they did..everyone seemed happy and they closed the Net. I also believe they popped up quickly on 6913 and then off.
I will try and pay more attention to the ID next time.
