I'm not quite sure what you're asking, but I'll take a stab at it. I use a CH Hotas, and I have a number of switches set up to change the tuning of the various radio channels, including the VOX channel. In particular, I switch between our squad channel and the mission channel for both radio channel 1 and the VOX channel (radio channel 5).
In regard to Cougar's rotaries, you can program them so that they issue digital commands. For example, if you had three different channels that you might like to use for your VOX channel, you could set up the ANT axis (for example) so that it would tune the first (e.g., channel 100) when in the first third of its rotation, the second (e.g., channel 150) when in the middle third of its rotation, and the third (e.g., channel 200) when in the final third of its rotation. It's been a while since I've programmed the Cougar, but I think you could use something like this:
ANT 5 3 (0 33 66 100) {/.radio SPC 5 SPC 100 ENT} {/.radio SPC 5 SPC 150 ENT} {/.radio SPC 5 SPC 200 ENT}
I'm not quite sure that syntax is correct, but hopefully it's close enough for you to get the idea. (In particular, I don't know if you need to insert spaces in the dot-command strings manually, and I'm just guessing as to what the placeholders for the spacebar and carriage return characters are.)
Another thing you could do is to put all of the channels that you would like to tune into a toggle list and assign one key to toggle through the list. That way, you could tune to any channel using just one key. That problem with that, though, if you have more than two or three channels, is that you would have to wait for Cougar to send each string before moving to the next one.
If what you want to do is use one of your rotaties to "tune" your VOX like you would tune a radio (i.e., so that you could turn the knob and continuously move through the radio channels), I don't think that Cougar can do that. Actually, I don't think that AH's radio system is set up to allow that sort of thing, so it's not really a Cougar limitation. The problem is that (as far as I know) the only way to "tune" a channel is to type "/.radio 5 channel# ". That takes a not insignificant amount of time, even when sent from a HOTAS with a 60 ms delay between characters, and will prohbit any sort of "smooth" tuning. Another downside is that while your HOTAS is sending the dot-command string, you are prohibited from sending any other commands to the game that are instigated by keypresses (i.e., changing views, lowering gear or flaps, etc.).
I hope that helps.
