You can use the power lines.

I remember a story from Dave Mills many years ago.  I tried to find it the 
other day, but no luck.

His WWVB gear wasn't working -- fading out due to EMI.  He drove around 
and found a factory that was spewing lots of trash.  I think it was going 
out the power line.  The FCC wasn't interested.  Anybody else remember 
that story?


A lot depends on how big an area you want to jam.  Cheap eBay GPS jammers 
were intended to cover the receiver on a truck but at least one managed to 
get an airport in New Jersey that was near a freeway.

I wonder how big an area a similar size and power unit for 60 or 100 kHz 
would take out with various non-monster antennas.
