I've been under the impression that VARA required Windows 10 or 11.
I assume that's incorrect?

The stick sounds interesting. How are you handling the PTT??

Both VARA (the modems) and VarAC Chat work just fine on Win 7.?? I've encountered a number of programs recently that only mention Win 10 / 10,? that actually work perfectly on Win 7.?? I think it's just that software publishers just don't bother to test on Win 7 anymore, and don't guarantee that their products will work on Win 7.?

I like to use Win 7 on these minimum-hardware projects because it takes a tiny fraction of the hard drive and RAM space of Win 10 and 11.? I have a "tiny" version of Win 7 that leaves out all the multi-media fluff, Internet Explorer, etc.? It occupies about half the installed space of a standard Win 7 build and about 1/4 that of Win 10 / 11.?

As far as the PTT goes, I use my home-brew self-powered tone-activated interfaces that don't require power, serial ports, or USB ports. The computer audio goes through a transformer and then a passive Schottky-diode voltage octupler that turns on a MOSFET switch for PTT.? I use very small caps in the voltage multiplier so it can key the PTT in less than 20 milli-seconds after the audio tone starts, unlike most VOX-type setups.

Or if one wants to provide external 12 VDC power, you could use a SignaLink USB which has it's own internal VOX system. ??

Or as I do on my Yaesu FT-857s, FT-891s and my FT-818 porta-luggie, turn on the radio's own dedicated "Data VOX" function from a menu.? (The "data VOX" fun? is completely separate from the usual mic-jack voice VOX function. It only responds to audio input on the back-panel mini-DIN data port.)
