Would it be possible to have DW coded so a single Channel could have a Receive only mode as well?

For example:
CHANNEL 0
MODEM 9600
RCV_ONLY 1200

If so, I can put a request on the github site.

I think you can already do that.? From memory:

ADEVICE? plughw:1,0 null

I think that was the right syntax. Basically tell DW that there is no audio device for transmit.?

We used that on a Raspberry Pi 4B as a tattle-tale packet monitor (*) for our club repeater.? For some reason, allowing DW to open the audio device for transmit messed up the other audio channels, even though it never sent anything.? Something unique to the early 4B models from what I was told.

(*)? The user interface of some Yaesu radios make it very easy to misconfigure APRS to beacon on the repeater-assigned VFO.? We kept hearing "BRRRRRAP" come through every 10 minutes but didn't know who it was, so added DW and a cheap audio dongle to the existing Pi that hosted our Echolink / Allstar connection.

?I think you missed the concept.? If you look at the configuration example, the request is:
? ? ?RX/TX at 9600 baud (hence MODEM 9600)
? ? ?ADDITIONALLY RX (decode) any 1200 baud signals on the frequency.

Ah...? "never mind!"

Sounds like a good suggestion.
