I can't imagine anyone trying to measure such tiny changes without 
extensive ground systems and very accurate and stable FS meters on a 
ground wave path. Sky wave would be worse yet, especially with all 
the multipathing at modest distances.

Exactly how do people make such tests, and isolate the causes and

I've sent an e-mail trying to obtain a copy of that. It might make it 
easier if someone who has one can copy it and I'll pay for it.73, Tom
