#3 Airspy HF+ "Discovery"

[jerome]

Cemaxecuter,

I recently bought an Airspy HF+ "Discovery", no particular problem to get it running with gqrx, I just had to add this udev rule (which you may want to add to the base image?):

cat>/etc/udev/rules.d/52-airspy.rules<<EOF
ATTR{idVendor}=="1d50", ATTR{idProduct}=="60a1", SYMLINK+="airspy-%k", MODE="660", GROUP="plugdev"
EOF

Worked fine afterwards with gqrx, but not SDRAngel, it appears in the device tab, but can't seem to get any spectrum appearing nor audio out. Would you have any pointers, thank you.

Finally, have you tried to RX POCSAG payloads?

This is great to know and I'll for sure add it. Glad to hear it worked with gqrx, but I you're not alone with the sdrangel problem. There's a long thread about the problem with i think the devloper himself saying he is not sure what is causing the issue.

I havent tried rx pocsag yet. I'll have to though.

Thank you for the note on the udev rules. I made sure to add them in DragonOS Focal R17. I'll also have to most likely address this on DragonOS Pi64 before doing the next release.

I'll leave this open till I can find out more info about SDRAngel.

so what i have found is that if you force usb ports to usb 2.0, SDRAngel in DragonOS Focal with no other changes will see and be able to use the HF+. To me this seems like an issue with their code as no other software on the same machine needs this done. I logged a ticket, but have not heard much besides someone comfirming they two needed to set the system to usb 2.

The other option at the risk of breaking bladerf-wiphy, I dont think many are using it is to upgrade to the hwe kernel.

sudo apt-get install linux-generic-hwe-20.04

Hopefully the SDRAngel code will be updated and none of this will be required, but it is two working options for now.
