[Lowfer] QRM or LOWFER?

[Gedas]

Hi Garry. Really great analysis of the signals.  My capture was just 
prior to sunrise, I think it was around 7:30 AM local EST. It would be 
really neat if someone was experimenting and a new signal available.  
Tonight I will try to get my frequency dialed in more accurately than it 
currently is. Last season I had captured WH2XXP several times at around 
the same time so this should be interesting.  TU again. 73

This is why some people appear bright until you hear them speak.
