I have an end fed wire feeding two SDR-iq remote server receivers about 
30' over my home/repeater sheds back up diesel genny. A small (50watt) 
panel sits atop the genny housing and keeps the starting battery 
charged. The charge controller was a PWM type, and essentially wiped 
out several HF bands. Swapped out the expensive controller for a more 
cheaper one and problem solved. 

The repeater site (APRS WX Digi too) has a Morningstar PWM controller 
too, but a jumper kicks it out of PWM, and is a pulse type charger. 
Remote HF base and two more SDR remote servers are RFI free once I 
placed the jumper on it. 

Whirlpool Duet washer is a whole other story, located only 15' below 
the end fed wire near genny. That took an AC line filter and 2.5 inch 
toroid ring to cure!

It's only a hobby... Right?
