Re: how can add antenna be used for both rx and tx, and how can rx and tx be amplified?

So? That only makes it slightly more difficult. A fixed antenna,

terminals so that you can talk to each other anywhere in the bird's
footprint.

The modules I'm using don't give any sort of feedback about signal
strength. The only way I know I have a signal is if valid data is
coming through.

How difficult would it be to figure out signal strength? Methinks
probably fairly


Not really. Its only as hard as you want to make it, like every other
thing in life. If you want to do the job, you find a way. Locate the IF
amp and tap into it. If you can't find the AGC circuit you can feed a
small sample of the IF signal into one of the chips made for cell phones
with a RSS output. Amplify it if needed, and use it to control the
motor drive. Tube car radios tuned for maximum signal strength in the
late '50s, with just a handful of extra parts. Look up "Wonder bar".
You should be able to do better than a 50 year old design without
breaking a sweat.
