DSDplus Not decoding Voice On Ham Repeater

I think this is a Ham Radio repeater any idea why DSDolus is not decoding the audio ?

The radio ID is not a normal registered number, but there is no real requirement to do so. I would suggest your SDR is not 100% on frequency so try changing frequency up/down slightly to see if you can get rid of the errors your getting

Try finding a narrow band transmission that you know the frequency 100% and see what frequency the sdr shows it as. I had to shift mine a fair bit.

Its bang on on all other things, I had to shift my ppm to 32 to get central on a frequency, thankfully I pick up radio mic's from the local crem so I get a good close constant signal, it's ideal for getting it all setup.

Even now I am searching the DMR range and have a good clean decode on the metro centre security on 440.462 so I don't get why I am getting issues, as I also had the same sort of garbled transmission on 456.750 I think , it was, was only a short burst and it moved on.

Change to searching to 6.25 steps instead of 12.5 and that has worked, its not ham radio though its more metro cemtre security
