Re: LF: Broadcast audio splatter on 136kHz

Hi Alan

Just like you said - i have no personal expierience with the "rusty bolt" 
effect on LF/MF, and am extrapolating HF ideas down to LF :) Hypotheticaly 
speaking the structure size to get enough voltage into a metal-metal oxide 
junction is not that great. A metal fence >100m long should be enough for 
local signals.
Paul-Henrik gave two frequencies: 171kHz and 225kHz (i can't see how they 
can give around 135.4kHz via mixing, so there is probably a third station 
involved). These could be Radio Russia from Kaliningrad (600kW) and Warsaw 
1 from Solec Kujawski (1MW). Obviously the two are not local to him, so 
ICM might be probable (the "rusty bolt in the sky" :).
