Heelo to all,
thanks to a friend who has prepared an exploitable tetrapol-kit on kali and raspberry 4 I ca play with. The hings are complex for my old brain to undertand the sources :) I got some unencrypted communications and I am very happy. ( unfortunately I can't use my SDRPlay receivers RSP1A and RSP2)
I get oftenly a lot sync_fail or broken frames. The RF signals are very good and strong. I try to change rf gain values, sure about the ppm correction of the key.
Do you have another idea or tune something to prevent the losses ?
Anyway, warm thanks and big applause to the coders !
I wish to all a very good christmas and happy new year 2021.
