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.
