Has anyone worked with Maxar uhf radios for linking. We're looking to install these radios asX-bandtransmit units for our voting system. We`re using GE Pheonix radios but would like totry True FM.. The Pheonixwere convenient because they are programmable. The Maxar`s would be set up with GE MVP
I am experiencing the same thing on a GR500 Motorola repeater with a
community tone panel and a 6 cavity mobile style duplexer.
I suspect some sort of feedback.
