requires a tone on receive to break your radio's squelch
Tone mode only does one thing: send a tone on transmit.
Also the Cherokee AH-50, which is the 6m big brother to the AH-27 (CB variant). They were produced from about 1995 to the early/mid 2000s. FM-only and able to use with repeaters. Very basic radio but back then, choices were limited to this radio for a 6m ht/handheld.
