We’ve been testing with a couple of radios with family members, we all hear the squelch tail but no voice. I have been as close as 10 miles to the repeater and in direct line of sight out to 20 miles with some obstruction, the results have been the same. On the handheld radios the antenna is an Abbree AR771. On the vehicle it’s a midland MXT500 micro mobile with an MXTA26 antenna on top.
