This duplex mode allows a repeater (rather than app_rpt) to perform the repeat function. This is also known as in-cabinet repeat. Duplex Mode 3 is unique to repeaters and is not likely to be used on simplex, half-duplex nodes or hotspots. Setting '''duplex=3''' in rpt.conf prevents Rx repeater audio from being sent to the repeater Tx. However, courtesy tones, morse code, voice messages and link audio are still sent to the repeater. PTT is continuously asserted upon a valid Rx signal.
