With the introduction of any new system there will be an evaluation of its success and an assessment of the positive and negative aspects of its operation.
I certainly think its worth a letter to 1) The operators 2) The licensing organisation 3) The RSGB EMC committee.
The government's regulator Ofcom now incorporates the Radio Investigation Service. Unfortunately, since January 2005 the 'privatised' RIS now only responds to cases of reported interference.
Their remit no longer includes initiating monitoring tracking and resolving interference or unlicensed operation.
No action.
A few timely letters may get a 136kHz 'notch' filter placed in the feeder.

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

My location is near Chorley, Lancashire (IO83qp)
