[IRCA] Fwd: [mwcircle] Bird Migration affected by LF & ME radio signals

[Nick Hall-Patch <nhp@xxxxxxxx>]

from MW Circle....the interesting thing is that 
this turned out to be very much a local problem, 
as moving the test site one kilometer allowed the 
birds to re-orient themselves.  So, local electrical noise?

I've often thought that the way to defeat 
electro-smog is to make it an environmental 
issue...the possibilities are endless.   Imagine 
putting the attack dogs of Greenpeace etc. onto 
the  DXer's problem of local electrical noise, 
which surely can be construed as causing health 
problems.   (after all, a good blast of local 
noise covering the latest DX can be shown to 
raise the blood pressure, but what of those long 
term effects of RF exposure, hi.)

best wishes,

Nick
