Hi David, check out SydneyOwl/g90toolkit on GitHub. He's been looking at the g90, which I believe shares a lot of commonality with the g106. It's too good a radio to let the software cripple it.?

I had mine out in Wisconsin the last couple of days for a POTA activation. Between the g106 and a cheap 50 Watt amp, it's just great. And it runs for hours on a 20Ah battery.
