Thanks, Tom - interesting piece. Our HV distribution here is 7500V, so our cutouts may not be the same series, but it strikes me as worth asking. Also, this may belong on Towertalk, but this procelai

I use my car radio, set to the top of the BC band, then a Radio shack portable SW receiver to get close, and a handi-talkie that receives AM at 136 MHz, with the Moxon antenna from the QST "sniffer"

Mike, I have found that my small local electric company, which has zero capability for finding RFI sources, is great about coming and fixing them if I can identify the pole or the neighborhood (withi

It's black magic. No seriously, lightning and the lightning tolerance of individual units is incredibly variable. For example, when we took our big hit in 1994 none of our phones were affected, but t

I wonder if maybe it is something else entirely. A dozen years ago I had this sort of RFI on a couple of discrete frequencies in the 80-meter band. I traced it to a neighbor's house, where we discove

I guess I should have emphasized that the RF interference this generated was discrete frequencies; as I recall it was at abt 3517, extending below that frequency for about 20 khz at diminishing stren

My bet would be on the electric fence, Kelly. They are very common in rural/semi-rural areas. The only thing that is a little odd is that you don't report hearing it on the lower bands. A properly ma

In my experience, 1-Hz "ticks" are almost always an electric stock fence with a problem, such as a wet post or weeds partially shorting it to ground, causing an arc. However, they aren't band-specifi
