I have a pair of Midland GXT 1000 radios and a Radioddity GM-30. They can communicate on channels 1-22 if I do not use a CTCSS or DCS tone.
If I enter either a CTCSS or DCS tone, the 2 Midlands can communicate, but not the GM-30. I am using the CTCSS and DCS charts in the GM-30 manual, so the frequencies should be correct.
Any idea what I am doing wrong?
