If anybody has any estimates (or measurements) of the increase in signal 
strength to be expected in the following areas they would be of considerable 
interest to the cave radio fraternity: South Wales, Derbyshire (Peak District), 
the far west and north west of Yorkshire (the area where they sometimes have 
Lancashire postcodes!!).

Yes, saw it myself this time. It only added about 4 dB amplitude in a 10
kHz bw and I couldn't see much difference in sidebands at 137 kHz.
Rugby and Lessay are very roughly the same distance from me.
You might have a look at relative amplitudes - I haven't got a working
Loran-C rx at the moment.
Will have another look today.

 Dear Group,

 a second LORAN-C transmission from Rugby (GRI 6731-Y, 27.3 ms delay)
occured today between about 8:30 and 16:10 UT.

 Sorry for the a posteriori reporting - I suppose real-time uploads of
LORAN traces might be more useful, but the second computer used for
monitoring on 100 kHz currently cannot be connected to the internet. The
corresponding lines on the LF screengrabber (eg 135923.340 Hz, mostly from
Sylt) did not show any significant change, but at a distance of 923 km not
much effect would be expected here.

 73 and best wishes

 Markus, DF6NM
