Midland model GXT710's transmitting and receiving on different channels

[esimmons682]

I have two Midland GXT710 handhelds which have barely even been out of the box but are too old to return.
They both show the TX icon when the PTT button is depressed, but only one receives anything. If I put one on ch4 and the other on ch18, everything works fine. Any ideas? Can the transmit or receive freqs. be tuned internally? If so how? Thanks for any help.

I know this post is old, but I'm just seeing it and see that it has not been answered. FRS-18 and GMRS-4 are the same receive frequency, 462.625, the difference is transmit. A FRS radio operating on channel 18 will be heard by other FRS radios on channel 18 and GMRS radios on channel 4. BUT, a GMRS radio operating on channel 4 will not be heard by FRS radios UNLESS the GMRS radio is transmitting simplex (direct), OR the FRS radio is hearing the GMRS channel 4 repeater. GMRS-4 receives on 462.625, but transmits on 467.625.

This is normal. Your midland radio in gmrs mode is set to operate thru a repeater. Frs radios are not allowed to do this. Your midland radio is designed to transmit on gmrs repeater output channels from ch.15-22. Frs ch. are 1-14 so if your midland unit has the option to use 5mhz. offset for repeater use then channels ABOVE ch.14 will be transmitting on 467.550-467.725mhz.

Not true at all. The model 710 is a typical bubble pack radio with the normal FRS and GMRS simplex frequencies. It has no ability to transmit on any of the GMRS repeater input channels. I suspecft the problem is one radio is set with a CTCSS/DCS tone on receive and the other is CSQ, hence only one radio works when set to the same frequency.
