Hello All, I have a Btech DMR 6x2,(the original) great radio and fits my com needs to a “T”!! However I’m having issues with programming 2 tone pairs to different channels the tones are right , but the programming software will only let me assign tones pairs 1-11, in the software you can program up to 16 different 2 tone pairs. Tone pairs 12-16, cannot be used. I checked both the firmware and the programming software and both are the most current version, other than the 2 tone issue the radio works great. Can someone please help me? Thanks.
