Thanks for your feedback.
All the documentation about the project is directly on the hackaday
page, follow the links on the table :
https://hackaday.io/project/164092-npr-new-packet-radio
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?
