Nothing significant in the spectrum

About 1uW should give some hint in a hour and very significant
peak on an 8 hour spectrum.

You made a long transmission with 30mA, from 2016-06-26_13:00
to 2016-07-31_08:00, 34.79 days.  No trace of the signal even
with a coherent daily stacking gain of 15.4dB.  Wait 58 says
0.036 fT for your ~100nW, which should have been visible in
one day, say 8 hours.

So something is not adding up.   Maybe ERP is much lower
than estimated, or the propagation near the mode 2 cut-off
frequency is more attenuated or suffering a variable phase
due to dispersion.

Will be interesting to see how the 65km experiment works out.
