I note that at the advertised bit rates, the OBW (occupied bandwidth) may
exceed US Regulations for 70cm. However, the chip used, is also claimed to
support 33cm.
I am interested in the new packet protocol proposed by the project. Even at
a lower bps on 70cm (for the US), and full rate at 33cm, this has real
potential for mid-tier data communications.

Hello,
I am Guillaume, callsign F4HDK, a french amateur-radio operator, and a
hacker-maker.
I would like to share with you my last project : NPR (New Packet Radio).
All documentation is provided here :
https://hackaday.io/project/164092-npr-new-packet-radio
This solution can transport bi directional IP trafic over 70cm radio
links, in a 'point to multipoint' topology, at datarate up to 500kbps.
This can be used to increase the range of existing HSMM-Hamnet networks,
at lower datarates.
It's designed for "access", not backbone, and not designed for H24 use.
Its is 100% open-source.
Do not hesitate to ask me questions about it.
I hope it will interest some people here.
73,
Guillaume F4HDK
