I’ve been continuing with my testing on my Pi 5. Winlink + VARA HF or FM are working pretty well. Stability isn’t as rock solid as I'd like, but I can always fire up Winlink Express and send/receive emails reliably. (If I leave it running for hours, as I need to for Winlink Wednesday, the Winlink Express process croaks at some point, every single time.)

Two things I have not had ANY success with, though. ARDOP TNC and VarAC.

For the life of me, I can’t get the ARDOP TNC to initialize. I’ve compared the configuration settings side by side with my windows (ptui!) system, where it runs just fine. The ARDOP and TNC windows open just fine, but the TNC fails to initialize on 127.0.0.1. When I configure the TNC window manually do launch on 127.0.0.1:8200, that configuration fails to persist. Next launch, it’s gone again.

And then there’s VarAC. I installed it using the installer. I installed the fonts recommended on the VarAC web site. I enabled Linux mode in the VarAC.ini file.

It launched and seemed to run once for me, and since then, every time I launch it, the VARA HF window opens, then the VarAC window opens, but the fields are black and the window is unresponsive.

Has anyone else run into similar issues? Were you able to resolve them? Suggestions?
