Trouble with Range on Acrobee75: Need Settings Help

Might not be software/settings issues. Depending on your goggles/RX, it could just be that you've reached the limits of what can be provided by the hardware. I had the exact same problem when I was running a set of BetaFPV VR03 goggles, which only had one antenna for reception. Upgrading the antenna to suit your needs might grant some temporary relief but if you *are* pushing up against the edges of your hardware capacity, there's only so much you can do.

What goggles/RX are you running?

I think this might be the problem, but another problem I'm having is that the goggles are showing me the following for band options (no band F):
