One of the things Mike Wisnewske KC0TAF showed us was the "hiding places" Windows puts settings that can affect VARA FM.

When I checked one of my under performing stations - sure enough I found AGC (auto gain control) on the mic in enabled!

Since YouTube is often our friend in these situations, I found a short video that gets to the point and shows you where to look.

One of the other things they mention is making the PC speakers and mic the default. I wasn't able to do that always.

I might add that with my mini PC there is no native microphone and Digirig is the only default device option, so I left it.

These settings are what caused me to struggle with my VARA FM station when I initially set it up.? This is very good information.? Thanks Mike.?

I heard the fellow in the video mention he was using a Baofeng FM handheld tranceiver.

Someone asked about using that radio at the workshop. Note the video said he had to use wide VARA FM mode to make it work.

The Digirig store has a cable pair for that radio too - one for operating VARA and one for Chirp programming.

Also, we had trouble finding the Silicon Labs link for the CP-210x UART driver needed.

Here it is, you want the universal driver on top.

Here's the Digirig help page for installation where the link is found.

Something worth noting for Windows 11 users is that the AGC will turn itself back on after an update. A sticky note by your monitor would serve as a handy reminder. I've not noticed this to be true for Windows 10.
