LF: Re: Loran Anthorn

["Markus Vester" <markusvester@aol.com>]

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
