Yes it would be nice to see what your normal signal looks
like Markus.

The main disadvantage of the filtered bearing scheme is that
it can't resolve independently two signals arriving on the
same frequency from opposite directions.

Switching off the bearing filter and just steering the
cardioid would not suffer that problem.  Hence why I
want to build that option into the next version of fbins.

Will be interesting to see if we can see your 2.5 uW!

A fresh batch of spectrogram data will upload to the
server soon... extending the display to 14:00 today and
back to 21:00 yesterday.
