Paul, this sounds like something that happened to me several years ago. ?If you loaded the driver?after?attaching your xcvr, Windows may have already identified your connection and “helpfully” installed its own driver. ?My solution was this:

• Open Device Manager
• At the top menu line, select View::Show hidden devices
• Delete the drivers for all instances of ?USB Audio CODEC and Silicon Labs Enhanced and Standard COM Ports. Open each of the following to find them:
• Audio inputs and outputs
• Ports (COM and LPT)
• Sound, video and game controllers
• Detach?the interface cable between your computer and radio
• Re-install your Silicon Labs driver
• Connect?the interface cable between your computer and radio

I hope this helps. ?I know how frustrated you must be, having dealt with this problem for over 2 weeks. ?Best of luck.

?You could try running VarAC, it is a very popular way to "chat" using Vara and if all else fails you can see if you are getting out as the PSK reporter will show your signal being received. Most users are active on 20m (14.105 calling/centre QRG). Assuming you are actually being received with VarAC, your next check is Winlink.

VarAC is popular but sadly many seem to only want to "beacon" and not have a QSO...

Paul;

Do you have another radio, that you can use to monitor your transmit signal?

I find that is one of the best tools you can get, for diagnosing problems with digital modes such as VARA!

Hi Paul,
Is the radio transmitting?? i.e. does the radio go into transmit (com settings).? If so, is there audio (Windows Sounds and Sound Settings).
On the VARA display, are you seeing data wave forms (Windows Sounds and Sound Settings) from stations you're trying to connect to.
I'm assuming the VARA and Winlink Express Settings are correct.? (Soundcard Settings in VARA and Radio settings in Winlink Session window).
I struggle with this as well with different setups and soundcards.? Radio settings for internal cards can also be frustrating.? I haven't setup my 7300 yet so I'm no good there, and I run Windows, so I'm ignorant on VM on Mac as well.
My path to success has been to be methodical and document everything.? Taking screenshot helps in that regard.

Best of luck.? Don't be shy about walking away and clear the head.? Please share your inevitable success.
