Troposcatter Propagation

When the bottom end of Band 2 is devoid of Pirate and RSL Stations I can receive signals from Omroep Zeeland, on 87.90MHz located at Goes in The Netherlands. The distance from Telford to Goes is 450km or 280 Miles. {Another good example was France Info on 105.20Mhz from Lille, a distance of 432km or 268 miles but alas this frequency is no longer clear in my area}.
The recording below was made in July 2007 under very flat conditions as the weather in the U.K. was one low pressure system after another with no tropo enhancements.
