I just got notified by RisingHF that they are now FCC certified for the RHF0M301 gateway module. I’m going to do some more testing with it this week. We are also finalizing our own node that uses the TN2903 chipset that should be able to integrate with any gateway. More info here:

We are using RN2903 to communicate using peer to peer mode using our own protocol, but also have a mode where you can set the LoRaWAN settings on the RN2903 and pass data directly. It should work great with the RisingHF gateway and then get data via TTN.
