Ok... to answer my own question from earlier... I found the detail in install.txt... I knew I had read something about it before...
When we need to connect an external program, let's say wsjt-x to sbitx, the sbitx will play
the audio to the speaker (hw:0,0) as well as hw:1,0. The wsjtx-x will capture this using
hw:1,1 as the audio capture device. Note that the hw:1,0 and hw:1,1 are working as a pair.
To pick up the modulating audio generated by wsjtx (or other external programs), the playback
device of the external program should be set to hw:2,0 and the sbitx will capture back the
transmitting audio from hw:2,1. Again, hw:2,0 and hw:2,1 are operating as second pair.
? ? ? ? ? ? ? ? ? ? ? ? SBITX Audio ? ? ? ? ? ? ?WSJT-X Audio
? ? ? ? ? ? ? ? ? ? ? ? hw:0,0 -> Speaker
? ? ? ? ? ? ? ? ? ? ? ? hw:0,0 <- Mic
? ? ? ? ? ? ? ? ? ? ? ? hw:1,0 -> Line out ----> hw:1,1 Mic In / Capture
? ? ? ? ? ? ? ? ? ? ? ? hw:2,1 <- Line In ------ hw:2,0 Speaker
... so this should make working with third party apps on rpi quite straightforward. As mentioned earlier IMHO I think it would be good to drop this into an Appendix in the user guide.

i'm not yet able to understand all of this, but people are also going to want to be able to use an EXTERNAL COMPUTER and connect to the "radio" with soundcard input/output and PTT and CAT control.? ?Having a connection emulation of an FT-something or ICOM-something will make it much easier to use best-in-class tools for Field Day contesting, for example.? ? the integration of N3FJP? and WSJT-X (in contest mode) on a single IBM PC is much preferable than working on a 7" screen in a Field Day contest, for example....
so I'm dumb enough that I don't know if this type of interface is still in there, but I hope it is!!
Otherwise, we'll soldier forward anyway.

I am super excited about js8call but the screen real estate that it takes is impossible on the sbitx. I am studying the code and hopefullt, I should be able to progra. it on sbitx, natively. - f?
Hi Ashhar,
Thanks for the videos.? They are very helpful.? If you are taking requests (and I hope you are) when you have the time, can you demonstrate a JS8Call session?
Again, many thanks, Scott
P.S. If DNL is on time, I hope to have mine up the night of 3 Aug (US ET). Woo hoo!
