Hi David,
 
I have copied my reply e-mail from when the interference was first seen which includes times, dates & rough levels of increased noise etc. I hope it helps.

Hi All,

After reading the mail at mid-day today (22/06/2005) reference LORAN transmissions from Rugby I carried out some checks. Using my G3LNP loop & Spec Lab I compared noise levels with previous Spec Lab captures & I am also reading about a 10db or more increase across 136 KHz using on the spectrum graph on Spec Lab. The waterfall display is showing strong LORAN lines all across the display, considering this is at mid-day is it going to be worse at night in darkness? if this is the case it will be useless for me. With the G3LNP loop connected straight to the Yaesu FT-747 & the loop tuned to the 136 KHz band the signal strength on the S-Meter has increased from S4 to S9.

My location is near Chorley, Lancashire (IO83qp)

Regards,

Gary - G4WGT - IO83qp

Dear LF Group,

Bad news... This morning at about 0740utc the Rugby Loran station is definitely operating - At my QTH the 136kHz audible noise level has increased by about 10 - 15dB as a result.

Cheers, Jim Moritz

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
 
 
 
 
Dear Mr. Bowman,

I have been forwarded a copy of your email to the International Loran
Association.

Could you please let me have some details regarding the interference
you are
experiencing, including what it sounds like and times of day that you
are experiencing
it?

Best regards,
Paul
