Hello,
I am using a Zumspot simplex hotspot with DMR, C4 and NXDN for a while.
Now I am trying to setup a MMDVM Duplex modem for NXDN. The modem had preinstalled firmware MMDVM_HS_Hat_Dual VR2VYE, version 1.5.2 and works fine with DMR and C4FM. NXDN signals from two different radios are not detected at all.
Calibrating the frequency via SSH using "pistar-mmdvmcal" works and the Error rate for NXDN is adjusted to almost "0". So the frequency is not the problem. I am confused, that NXDN is detected during frequency calibration, but Pi-Star does not detecting any NDXN rf signals at all.
Pi-Star is running version 4.1.6, which also works on my Zumspot with NXDN perfectly.
Who has any hints?
