10 elements in 915Mhz.  80m 10 elements would be hard to do.   Fun, maybe, 🤔  ha

LoRa on 900Mhz band.  

Trees suck up the signals.  

900 works ok line of site with low humidity.  

We need some high sites.   It would also be good to have a polling or token-passing protocol.  We’re sharing a channel with an unspecified number of emitters, and many of those will relay messages they hear.  This creates channel congestion/collisions.  

The max observed throughput is going to be orders of magnitude below the modem bitrate.
