Hi Markus,
Thanks for that explanation, that must be the reason why I was seeing
additional lines. All is normal from yesterday (30th).
Cheers,
Gary - G4WGT.

Hi Gary, LF,
according to my 100 kHz monitor, Anthorn Loran came on the Lessay chain rate
(GRI 6731) yesterday 10:25 UT. After some adjustments of the transmission
delay, they reached their "final parking position" in the old Rugby slot
(27.3 ms after Lessay) at about 11:40. The sideband lines should now be on
the usual frequencies, i.e. exact multiples of 100 kHz / 6731 / 2.
The time-domain graph was recorded 2007-11-30, 10:00 (bottom) to 13:00
(top), using 22050 samples/s (left to right) and phase encoded as colour.
Best wishes to all
Markus, DF6NM

Hi All,
Can anyone tell me how to calculate the extra lines produced by Loran
Anthorn on 137 KHz. I now have twice as many lines as before which are not
shown on my spreadsheet list of line frequencies previously seen.
My location is considerably closer to Anthorn than Rugby although I would
have thought that if the pulse generation is the same I will still see the
same lines but stronger.
Any comments please.
