LF: 136kHz transatlantic propagation

["Steve Dove" <dsp@hifidelity.com>]

Greetings,

Since there is talk of possible transatlantic tests again on 136kHz,  it may
be of interest that for some little while I've been running a near-real-time
signal-vs-time graph of DCF-39 as measured here in Pennsylvania.  The
site is still very much a work-in-progress, but should be useful as is:

It operates on much the same principal as Dex, W4DEX's measurement
of HBG at 75kHz at:

(On the face of it, there seems to be NO correlation between 73kHz and 
136kHz, other than they both happen at night!).
Of course, for comparison with a shorter, intra-EU path, there is Brian,
CT1DRP's measurement of DCF at:

       73 all,

               Steve
