Thank you everyone for your observations. =20

Quoting from my article on eLORAN in CREGJ issue 67 (and referring in partic=
ular to 87-90kHz):

"Assuming the Anthorn station has the same ERP as Rugby, rough calculations=20=
suggest that the interference level in the North Yorkshire area would increa=
se by about 4dB, the level in the Peak District would decrease by the same a=
mount, 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 streng=
th of other LORAN transmission."

Can anybody (Mal?) tie up their observations with these estimates, please?
