At the next cave radio field meet in the UK, which is likely to be in September 
(but the location is not yet decided), it is hoped to make measurements of 
Loran signal strength on 87kHz and compare them with those in past years.  Cave 
rescue organisations which use Heyphones and Molephones are also being asked if 
they have noticed any difference in interference levels.

A note will also appear in the forthcoming CREG Journal alerting people to the 
tests.

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

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
