Sorry by dvm I meant mmdvm-sdr.

Can I use negative value in dmrtc if I have negative value in qradiolink? My
radio's TX (mmdvm rx) needs to be below radio's RX (mmdvm tx).

Well, in that case the split is positive, not negative in both qradiolink and
dmrtc.
If the radio transmits at a frequency lower than it receives, then qradiolink
receives at a frequency lower than it transmits so the split is positive.
The same split value needs to be entered in dmrtc.
Mathematically, RX_freq + split = TX_freq. It does not matter if split is
positive or negative, this equation always applies for qradiolink.
