Well I finally got the cable delivered for the uhf/bluetooth hub connection. Clarity is fantastic, be it only mono. Smaller than an i phone with a very large ptt button. I have ran a seperate ptt button to the joystick control. Beats having to fit a uhf to your aircraft. I have tested it only with my zulu headset but I expect that it would be compatible with all bluetooth makes. I also run my i phone through the unit at the same time. No wires and no mess. Great for those who want a UHF without mounting or an ear piece.
