How to troubleshoot Pro Stick (orange)

[rjanke1]

Good day!

I have a Raspberry Pi4b running Piaware with both a Pro Stick Plus (blue) collecting ADS-B Mode S data and a Pro Stick (orange) collecting ADS-B UAT data. They are setup correctly, individually serialized, etc. and were working well for a long time. However a few months ago my UAT hits dropped to zero and has consistently been zero ever since. I realize UAT hits are very infrequent, but to be able to pinpoint a date of when reception has ceased is a little suspect. (Also, both receivers are connected to individual, frequency specific FlightAware branded antennas with appropriate “as-short-as-possible” cabling…specifically 25ft…but as I mentioned everything had been running well.)

Is there any way I can trouble shoot the Pro Stick independently? I had thought to order a new one from Amazon.ca, and then return it if a new one didn’t prove to fix the issue, but there aren’t any currently listed.

Any thoughts on the matter would be greatly appreciated.

Below is how I tested my HEALTHY Orange ProStick whic I use for UAT 978 MHz

sudo apt install rtl-sdr 

rtl_test -t 

 

 

 

(7) REBOOT PI to restore your system

sudo reboot

Thank you for the detailed steps! It appears that mine differs at step #5

Particularly the PLL not locked! errors.
