Wouldn't that require mixing (distortion)? FWIW, I once tried using 2 CTCSS tones on one of my links (all G.E. MVP TX & RX). If they were 1 or 2 standard tone frequencies apart, the G.E. CG decoders wouldn't decode either of them. However, if they were 4 or more standard freqs. apart, it seemed to work. Bob NO6B
