[Elecraft] Odd Noise Located

 Over the past few days I started to hear a random popcorn popping type 
noise on 160, MW and lower. I had never heard a noise like this one.
I couldn't think of anything new around the house- and having no close in 
neighbors I was stumped.
Interestingly, the only NB that 100% eliminated it was my bedside TenTec 
RX-325. But I digress.
I took my KX-3 with a 24" whip on the BNC connector. AM mode  on 160M and 
headphones. After  eliminating any sources on the upper foors, I narrowed 
the search to my shop/lab. . More checking and I found a brand new LiPO 
charger that came with my new LED flashlight. I had forgotten I had even 
plugged it in. When the whip got close, the  sound was deafening.
The moral is- don't forget what's new in  the house and the KX-3 makes a 
wonderful noise source detection tool.
