[Boatanchors] Really Spooky Signal on 20 Meters.

[David Stinson]

OK, this is really weird. For weeks, the 20-meter phone
 band at my location has had this wide-band pulsing
 noise. Ran from about 14.240-14.330 MC 24/7. 
It sounded  "near field," so I finally broke-out my 
portable HF direction finder and started hunting. 
I walked out to the end of my driveway and got a
 good signal, bearing East of my location. 
So I went about a block to a local park and 
still bearing East. So I put the rig in the truck 
and drove East a mile. No signal. So I moved back 
half the distance to the house. Nothing. Half-way again.
 Nothing. In short, the signal, after being around 
for weeks, suddenly disappeared exactly 
when I started to hunt it. It has not come back. 
I find this strange and makes me a little paranoid.

Here's the noise:
