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.
