That is interesting. I've wondered why the ISM targeted radios hadn't been used by us. There may even be some 9600 bps packet version that would work on 2m. Don't have the hardware skills to attempt a project so never looked that closely the radios. The NPR might also find us on the 33 cm band. Think I've seen ISMs in that band.

here in dl they develop a similar thingy around a pluto

high speed access to ham radio network without line of sight (70cm used here but all higher bands are possible up to 6 gig)

a pluto ... an amp ... and a high speed rx tx switching device (relays are too slow) ... (its an rf diode switching ic used from skyworks)

that is user end

base station running fullduplex with filters (pluto amp and filters)

infos here on github

ps pluto can use any band rx and tx so maybe you can work without filters but two bands
