You have often put a strong signal into Todmorden.

Daytime signal was usually about 0.1 to 0.15 fT.  Not far off
that now, except that the energy is spread across a few
bins in 278uHz resolution so appears weaker on the spectrogram.

Hopefully you have some E-field feedback to maintain a constant
radiated phase.  Maybe this is not working right?

Some reports from previous years
