Any suggestions? I have an rtlsdr feed by a 137 mhz QFH antenna. Where are files stored locally? How can I trouble shoot?

Hi! You can click on observation and check spectogram. Also, logs are available in journald:

journalctl -u r2cloud -n 200

In the log I am getting the usb_claim_interface error -6 error message.

When I reboot and run rtf_test or a FM radio command: "rtl_fm -g 50 -f 95.9M -M wfm -s 180k -E deemp | play -r 180k -t raw -e s -b 16 -c 1 -V1 - lowpass 16k” everything works well.

Do I have a permissions issue?

Maybe. Can you: 1) Check if no other software is using RTL-SDR 2) Check if kernel driver loaded first: lsmod |grep rtl ( See some remediation here https://stackoverflow.com/questions/43879570/usb-claim-interface-error-6-on-rtl-sdr)

There are 2 options: 1) Check the logs for the actual command. It should output something like: ./etc/rtl_sdr_wrapper.sh -rtl rtl_sdr -f .... You can run this command manually 2) REST API. Authenticate using REST API and execute immediate observation. See https://github.com/dernasherbrezon/r2cloud/blob/master/src/test/java/ru/r2cloud/it/ObservationTest.java for code example.
