INVALID CHANNEL is cryptic

[jmkristian]

If I configure two devices, like this:

ADEVICE plughw:CARD=Digirig,DEV=0
ACHANNELS 1
ADEVICE1 plughw:CARD=DRA,DEV=0

... the second AGW port is described to AGW clients as INVALID CHANNEL. An AGW 'X' request to this port elicits this response: {port:1, dataKind:"X", callFrom:"W6JMK", data:"00"} Which suggests that Direwolf rejected the call sign. Direwolf's log output is not much more informative: ERROR - Request to transmit on invalid radio channel 1.

I would prefer that invalid channels are not visible to AGW clients, or at least the log message says something about this port relating to the right channel of the first device (not a channel of the second device).

I used Direwolf built from source tag 1.7 commit de293a1f2526ec663 on Ubuntu 22.04.3 on an x86_64 laptop.
