Hi,

I just purchased the HackRF One.

I am trying to follow the lesson in "Software Defined Radio with HackRF, Lesson 1" 

I can get it to work on Pentoo, but I'd really like to be able to run on Ubuntu 20.04.1.   

On Ubuntu, hackrf is version (2018.01.1-2)

When I enter "hackrf_info", I get:

hackrf_info version: unknown
libhackrf version: unknown (0.5)
Found HackRF
Index: 0
Serial number: 0000000000000000088869dc35a1531b
Board ID Number: 2 (HackRF One)
Firmware Version: 2018.01.1 (API:1.02)
Part ID Number: 0xa000cb3c 0x00584358

The command "hackrf_transfer -r /dev/null" works as expected.


I found the gr-osmosdr and installed it.

Since wxgui is deprecated in GRC 3.8 I'm using the QT GUI Frequency Sink block.

When I try to run, I get the errors below.  I am attaching the py and grc files.

Any help or suggestions would be much appreciated.

Thanks,

Will Cummings
