John,
Loran is now audible clicking away since it moved to its new location, when
located at Rugby it was just about visible but not audible with me.
My loop antenna is E/W and if its located West from me I suppose it will be
fairly strong, whereas at Rugby south from me it was in my loop null, more
or less.
I have not carried out any exact measurements, since it did not bother me in
the past.

Thank you everyone for your observations.

Quoting from my article on eLORAN in CREGJ issue 67 (and referring in
particular to 87-90kHz):

"Assuming the Anthorn station has the same ERP as Rugby, rough calculations
suggest that the interference level in the North Yorkshire area would
increase by about 4dB, the level in the Peak District would decrease by the
same amount, and the level in the Swansea Valley would decrease by about
5dB.

How far these changes will be noticeable will depend of course on the
strength of other LORAN transmission."

Can anybody (Mal?) tie up their observations with these estimates, please?
