Hi Dave, Roger,
yes, Loran-C transmitters Anthorn and Lessay do
have a line on 137676.423 Hz (ie. 18534 times 50000 / 6731), confirming
Dave's frequency calibration. I have recentered the narrow slot to 137676.0, but
now we're surrounded by QRN already.
Roger, any chance of moving into the Eu or
TA window where Jean-Pierre and others are regularly watching?
Best of luck,
Markus (DF6NM)

appreciated
Roger,
LF,
Latest
screen grab attached. I switched to my 1.2m tuned loop, and your signal improved
by at least 3dB, maybe as much as 6 dB. See attached
screenshot.
BTW, I
make your frequency to be 137676.0. I have a small frequency error which makes
signals read high by 0.3 Hz. The line at 137680.40 is a locally generated signal
in 137680.0, which is pretty accurate.
The
line appearing at 137676.8 (137676.5 actual) is a mystery - maybe it's a Loran
line.
How
many watts are you puttting into your loop?
