Re: LF: Rugby test?

It wasn't Rugby that went off yesterday but Lessay. As luck would have it I 
was trying to debug some LORAN receive software that morning, and I couldn't 
figure out why it wouldn't work. It seemed to work in the afternoon and I 
couldn't figure that out either until the screenshot from Markus revealed 
all!  The moral must be - don't try to debug LF receive software on the 
first Tuesday of the month!
Rugby transmits a regular group of 8 pulses at 14.85/sec., and on it's own 
that would give a very regular buzz, although at a rather lower rate than a 
fluorescent light. When Lessay is on, it transmits both at 14.85/sec and 
13.11/sec and the 1.5Hz beat between these gives the galloping effect.
With Lessay off, the galloping stops. At least this is true in the UK.
