Hi there!

How do I decode this with my TRX-1:

"Dual Capacity Direct Mode (DCDM) is a DMR enhancement that can be employed when using simplex (direct) communication between radios. When operating with a DMR repeater, the repeater provides a sync signal for the two DMR time slots. Normally, DMR simplex operation between radios does not use time slots since there is no sync signal available. DCDM is an added feature that allows one of the radios in a simplex communication to provide a sync signal, thereby allowing the use of both time slots (i.e. Dual Capacity)."

I have such a system nearby, no dice so far with my TRX-1. Any hints?

Shall I provide an IF recording?

And: Does DSD+ get a grip on such DCDM signals? What about Uniden?

I know for sure there is a base station radio providing this sync signal. Around 5 mobiles are attached.
I also know for sure it is not E.
