I have a marker on the center of a local FM station. Is there something I am missing here
As stated in the wiki the tinySA can only do AM detection, to hear FM stations you need to use "slope" detection.
This is what I do to listen to the FM broadcast band.
Attach telescopic antenna
Plug in sensitive headphone
Set start to 85MHz
Set stop to 105MHz
Enable LNA
See all the FM stations appear
?Set RBW to 100kHz
Enable LEVEL/LISTEN
Grab the marker and move on the side of the FM signal (as shown above)
Now you may hear the FM station
For sure you will hear noise
