Hello Jim.
Thanks for the 'permission' I'll try and information gather for a
couple of days and then send them something fairly complete by the end of the
week.
Yes, a recording from Dave would be very convincing. I must calculate the
exact distance from here and try to get a 'specrogram' of the QRM. Thanks in
particular for the very useful 'added noise within a specific bandwidth'
figures.
Do you know if it's been operational recently on a daily basis or is it
still a few days on then a couple of days off while they make adjustments?
Regards
David
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.
