Yes, I'd like a screenshot or paste of the output from the hackrf_info command.

trying to send you picture, but keep getting mail delivery errors due to the size. Here is just the hackrf_info you requested.

Here is SDR++ screenshot looking at the FM broadcast band, nothing but that weird spike on the spectrum.

Neither the hackrf_info output nor the SDR++ screenshot came through. I don't think email attachments work. You would probably have more success interacting with the issue via the GitHub web interface.

Just wondering if you got the screenshot through github and if so, any insight on the problem. Also, I purchased the radio from Sparkfun, if that makes any difference. Thank you.

Thank you! It looks like things are mostly working, but you have a DC spike in the middle that you can fix with a firmware update: https://hackrf.readthedocs.io/en/latest/updating_firmware.html

Once the firmware is updated, you should be able to turn up the gains and see those FM radio stations more clearly.
