Just installed the new version 3.2.1. Love the new features but I think there is an issue with the cat control for PTT. When selecting a radio and doing a save the selection gets cleared. This may be how it is supposed to work. The other issue I see is that When using the cat control, one can not change the radio frequency from the VARAC User interface. This does work in the Omnirig configuration through.
To see this working, head to your live site.
When you upgraded to 3.2.1 did you also copy over the .conf file for cat??
Both expected behavior.
for first thing about not saving - read this : https://www.varac-hamradio.com/forum/varac-discussion-forum/ft-991a-rig-name
For the frequency - this screenshot will better answer your question.
