Dear David, LF Group,
Please feel free to use the "published" info. So far, the only day I
captured the exact times of operation was 30th June, when Rugby started at
0650 utc and shut down at 1526 utc, if the clock in my computer is to be
believed. At the moment, Rugby still seems to be operating the Loran TX "office
hours only" - it usually seems to come on about 8am BST, give or take 20 mins or
so - perhaps it would be a good idea to make some audio recordings as .wav
files or similar of the actual start-up. I guess this would be pretty
convincing, especially if G3YXM can make a recording! There was so much QRN
during the afternoons in the last couple of weeks it was hard to see on my
spectrograms where the transmissions actually shut down, but that may have
improved this week. But since the natural band noise is quite low in these
summer mornings, the effect of the Loran noise is more impressive then. I will
set my alarm clock for tomorrow morning...
Cheers, Jim Moritz

Loran
Hello Chaps.
Well, I think we have an opportunity to influence the future of the Loran
project at Rugby.
I made a complaint about the interference to the Loarn organisation and
they have put the Trinity House project manager in touch with me.
Typically for an interference complaint, they need times dates and description
of the sound.
Sounds I can do, but can someone forward some real dates and times as I
haven't noted the previous transmissions to a sufficient accuracy.
I suspect we won't be able to stop this, but we may well get them to
install a large notch filter for 136k.
Jim / Dave. May I use some of your previously 'published'
info?
Regards
David G0MRF
