I am suddenly noticing an interfering signal about every 16 KHz on 10M. Not evident on any other band, this signal is pulsed on about 1-second intervals, and looks and sounds like a fairly complex mo

Not to worry. These fences operate at VLF (around 15 KHz IIRC) . I have had one around my property for 10 years, and have never been conscious of it. It runs within 75 feet of the base of my tower. N

I couldn't agree less... I've been using my car radio to close in on noisy poles for a decade and more. Tune to the top end of the AM band and drive. Get close and take a portable radio from there. T

Well...my 2010 Outback and 2014 Acura TL both hear powerline noise fine. Clearly there's variation by manufacturer, but it's easy enough to test - just drive down the road alongside a power line. 73,

Anyone run into an RFI emitter with outputs every 60 KHz? It is stable,so probably not an SPS, and very loud - ~-60 dBM. First time I've run into this, and I'm hoping it may ring bellsbefore I try to
