Transmission1

Hi all I have a problem fm is working perfect when I try dmr doesn't pick anything up but when I go back to fm the dmr data is there any help would be grateful

Are you certain there is anything to receive? DMR repeaters regularly transmit idle bursts which don't contain any audio for your radio to decode.

Also make sure you have the right colour code for the repeater. You will only hear voice traffic if you're on the same timeslot it's being sent on and I recommend you make sure promiscuous mode is enabled.

Also if they have RAS (Restricted Access to System) enabled a DMR radio will hear nothing, but a scanner will hear it no problem..

I don't think amateur DMR system use RAS.

How do you know the OP is trying to receive an amateur repeater ?

We're in the amateur radio section

The HD1 can be loosely termed as a amateur radio than can be used for other uses, so between Amateur Radio - digital voice and data and Licensed (Commercial & Imported Transceivers), it is a bit of a toss up where questions go.. The OP is the only one who can guide us..

Yeah I have the promiscuous on also I can hear the dmr voices on a 2nd radio but cant hear it on the hd1 but when I switch over from dmr to fm I can hear the dmr noise so I am also on the right frequency

What's the other radio and how is it programmed? Is this an amateur system or business radio?

Md380 amateur radio I cannot get my head round why dmr side of things isn't working even done a factory reset and still same can hear dmr on fm switch over to dmr nothing at all

That is odd. Can you double check a few things? Make sure the channel is set to repeater mode instead of simplex. Made sure the colour code and timeslot are the same as the MD-380, and makes sure that promiscuous mode is turned on.

I have done all that and still nothing not to sure if it's anything to do with enhanced settings it's not picking anything at all up with promiscuous mode

Drop Promiscuous mode and use the TG

Tried still doing same it's got an old firmware on thinking of updating it see if anything happens

Could they be using enhanced privacy? I thought the DMR spec silenced a receiving radio when Enhanced/encrypted flag is detected unless the appropriate key is available. This would explain why you can still here the data on FM.
