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:

http://www.w3eee.com

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

http://www.gostanly.com/w4dex/index.html

(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
