Has anyone tried or is anyone using the VarAC utility?

This could be a potential trial to do with our partner club.
VarAC
Re: VarAC
Not a member of your club but I've used it a bunch of times. First, on HF you really do not need to pay the 70 buck fee to get the high speed version of VARA. In my experience, HF speeds are generally lower than the free version. If you like to actually chat (via typing) as opposed to merely making a log contact (FT8), this is an option. It has more features and options than FLDigi, error correction, pretty decent speed, pretty decent weak signal (and low power) capabilities. It's a fun mode. The VARA modem (and OFDM in general---FLDigi now has it) seem to be a solution for digital on HF with the exception that it is wider bandwidth. VarAC is 500Hz. Not wide, but not really narrow, either. You can use 2300HZ mode but pretty much nobody does. Maybe in an emergency for pictures or something you could.
I also use JS8Call.....VarAC is pretty similar but MUCH faster and can do more stuff. JS8 Call can do a QSO but is S L O W.

Re: VarAC
I’ve not tried VarAC as I’m usually on a Mac for digital modes. If I can get it running under wine on a raspberry pi I might try it. I got VaraHF working on a converted Chromebook running Linux under wine once but that was not a great experience
