A channel number between 1 and 13 (or whatever the max is in the current

region). If ZERO then the rule is "use the old channel name hash based

algoritm to derive the channel number")

If using the hash algorithm the channel number will be: hash(channel_name) %

NUM_CHANNELS_US is 13, for other values see MeshRadio.h in the device code.
