wew new #ArgoCD and #cloudflared tunnel for the #AREDN connected #RaspberryPi 5 🎉

still a lot more to do but this has been on my agenda for waaaaaay too long.

#NPR (New Packet Radio) is a custom #radio protocol, designed to transport bidirectional #IP trafic over 430MHz radio links ( #HamRadio frequencies 420-450MHz ). This protocol is optimized for "point to multipoint" topology, with the help of managed #TDMA.

Bitrate is 50 to 500kbps (net, effective bitrate), depending on the RF bandwidth chosen.

The radio modem is cheap (~80$) and home-made, with a 433MHz #ISM module inside (flexible enough to be tuned over the whole 420-450MHz band). The modem is connected locally with #Ethernet, therefore no specific software is needed on PC.
The modem is easy to build and reproduce.
You can add a #DMR radio amplifier in order to achieve 20W radio power or more.
The main usage is an extension of #HSMM - #Hamnet - #AREDN networks.
All the project is open-source : hardware, software, protocol specification.
