Hi, I can’t use VOX on my RT29.
I followed instructions as here:
But when I try to use it the RX radio do not recive the TX signal. Same channel with a PMR 446 frequency 446.13125 and 67,0 DCS
I activate the VOX option with PF1 well programmed and when I speck the green led switch on but nothing happend on the othere radio.
I can reverse operation with the other radio but I get same result. So I can not figure out how to use VOX.
