Thanks for your feedback.

It's not a Dorji radio. All the components that I have used have fast TX/RX commutation times : less than 500 microseconds in total. * 433MHz ISM band module (RF 4463 F30 from Nice RF) * DMR-compatible radio amplifier (VR-P25D from Vero-Telecom)

I want this!!!!!!
I note that you have used a Dorji radio module modules which have variable rise times in the order of over half a second. How did you overcome this?
Got a link to the project?

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.
