[Elecraft] K3 Getting a buzz, the wrong way

[Fred Jensen]

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.
