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.
