The pro’s will be by soon, but the quick answer is yes. I use a VHF/UHF APX7000 and my buddy and I can see the other’s position whether we use simplex, or go through the repeater, when we TX. He uses whatever model he has in his hand at that moment. I know he has an 8000 and various others from handheld to mobile. Obviously the GPS needs to be turned on as well.
By the way, I did some testing with an amateur antenna once and everything worked, but the GPS. Fortunately the Moto PMAT4001A is a fine antenna.
