Is there a surefire method to programmatically determine the radio type (series 1 or 2)? I see the firmware version VR command but that would require me to keep track of all firmware versions. There is a HV command but on series 2 it requires 1941, which seems to be firmware related. I can think of a few hacks, like sending an EC command… if it works it’s series 1, invalid command series 2, but I have to imagine theres a better more reliable technique.
Next question do all series 2 radio have sif header?
