EU signals > weaker than usual. Interesting hypothesis! I'm observing the signal from NRK/TFK, Iceland at 37.5 kHz (314deg., 2120km) round the clock since many months. The propagation path, compared to the trace of that cloud of volcanic ash, is almost "optimal" from here at North Germany. A preliminary check of my data does not reveal any significant effect. But that does not mean that any effects are impossible - only unlikely. And, of course, lower LF is not MF. Greetings from Kiel, Peter, df3lp
