I have been trying to configure my Openspot 3 for use with my ICOM F4400 to do native NXDN (not cross-mode) and have
been able to get the Openspot to respond to my radio. The RAN is set to 0 (although I have tried others). In digital mode, the radio can only operate either 12.5 or 6.25 kHz. I have no issue with native DMR, P25 or YSF.
Any advice would be most helpful.
