Re: [Discuss-gnuradio] HackRF + osmocon, RX works but TX doesnt

[Cinaed Simson]

You should post your HackRF questions to the HackRF mailing list

   https://pairlist9.pair.net/mailman/listinfo/hackrf-dev

Also, you should get to know your HackRF so you don't blow the RF amplifiers

In addition, you should at least ensure the installed HackRF libraries
and the firmware on the HackRF match - ideally they should be latest
version - which is rarely true is they are installed by the OS.
