I only did this twice. The first time was pretty discouraging, I'm a
little less than 200 km from the old Middletown CA LORAN-C station, and
I was seeing around a half a volt of very obvious LORAN pulses. It
didn't affect me on 160 directly, but ... the USCG shut down LORAN-C in
2009-2010, and now the K3 NB works great on 160. Never did before. I
remember as a kid, in So. Central Los Angeles, our TV antennas brought
the 300-ohm twinlead down to a window where it connected to a lightning
arrestor, and then went inside. You could put your fingers across the
two terminals and feel the buzz. You didn't want to lick your fingers
first :-) Without LORAN-C, my noise peaks are running around 100-150mv,
we're in a moderately rural area.
