Thanks for pointing this out John. I will putter around with Annaliese’s instructions… Exactly why I bought this little beast in the first place! Since my most of rigs are primarily ICOM, it will be interesting to mix it in with use of the built in sound systems of the 7100 and 7300. Also interesting to learn if trying this is not going to overload the Pi B 3+. RPi are cheap, so the ICOMs will probably be run by a cluster rather than with the DRAWS.
I still am struggling with getting an appropriate drive level for using fldigi and wsjtx on the IC-7000. Xastir/YAAC does work on the 7000 and all programs I have tried work fine on the FT-817, but properly configuring the DRAWS and IC-7000 for HF digital modes has bugged me since early December. My correspondence with Basil and Brian about that is here in the UDRC archive.
Love to know if there has been any “discovery” made about this issue.

Here is a screenshot from K7UDR's remote base. It runs a headless DRAWS™ HAT on a Raspberry Pi 3+. I access it from about 60 miles away over VNC.
On the right mini DIN-6 is an IC-706Mk2G. Which under CAT control over a second USB port. This radio doesn't allow PTT over CAT (CI-V), so applications must support an alternative keying method. Fortunately, direwolf supports PTT via GPIO on the Raspberry Pi/DRAWS™. In the screenshot you will Xastir running, using gpsd for position and direwolf for the packet modem.
In this configuration, both an HF datamode and Xastir/Direwolf are running simultaneously from one DRAWS™ HAT, using two attached radios. Any application that uses direwolf, should be able to take advantage of this type of configuration for packet applications. Data mode applications access either through native Pulse Audio support, or via Pulse Audio/ALSA mappings.
