The frequencies to be used for DMR simplex are defined in the UK Amateur Radio Band Plan. We share the analogue allocation as it’s noted FM/DV however DV users are not to use the FM calling channel as another has been allocated specifically for digital.

However, the 70cm DMR simplex frequencies being used have been done around its calling channel which seems not to raise too many issues with the RSGB however they have suggested keeping with the 2m DMR allocation due to the fact that 2m is a busy band.

The common UK settings are TG9 , Slot 1 , Colour Code 1
