I will do the adjustment to avoid the simplex mode... unfortunately, the GMRS V1 does not allow offset to be changed (it defaults to 5MHz) so the only thing I can do is to change duplex to +, and try again... for some reason, it is defaulting DTCS Code values that for some other tones I cannot adjust... there are lots of things that the GMRS V1 cannot have adjusted in order to comply with the FCC approval for GMRS usage.\ The plan is to set up the tone mode in TSQL for the 141.3 tone, cross mode tone-->tone, and duplex to + Let me know if this is not proper... I will then test with someone using the other radio out of simplex range to see if it works... wish me luck ...stay tuned for updates, and thanks again for your help... still lots to learn!
