Bandwidth & Step Size

Postby Skirge » Mon Jun 27, 2016 10:55 am

What's the recommended bandwidth & step size for searching DMR ? I have read conflicting opinions when googling this, some say 12.5 as it's NFM others recommend 6.25 and a ;lower bandwidth for decoding NXDN96.
I am still finding certain transmissions that stay garbled and show as "unknown".

I am 100% sure RTL Dongle its tuned correctly I used the ATIS at Newcastle Airport to make sure I was bong on frequency.

They're both right, DMR is 12.5 and dPMR (which NXDN uses) is usually 6.25, although the standard also allows 12.5
