HIGHLY recommend ANALOG users enable Tone SQ on your radio!!!!
Added TX PL of 100.0 / RX PL is still 162.2

Added Digital capability…
Following modes: are enabled, these trade off with each use, after a short time ~ a min of inactivity of any mode, and the repeater will listen for any of the following…
Goes for local and Network, some modes may get disabled if they are never used.
If there is interest in any of these modes let me know. If you can test the Untested modes, let me know if it works, if you find any issues.

DMR – Fully supported – Working. (Color Code 1) Time Slot 1 & 2 available
DSTAR – Supported – unknown if it works… who’s got a D* radio to try it out?
FUSION – Yaesu Fusion – Wires X is working.
P25 – Untested
NXDN – Untested

To switch from Analog to digital, just start using the mode of your choice, if that mode fails to connect, the repeater maybe in another mode currently… This will time out if activity drops off for a short time.
