[RFI] Heated dog water dish

[dalej]

Just want to relate a noise problem that I've had for a few winters.  Always in cold weather would this intermittent arc welder noise happen, especially bad on 20 meters.  Well, I finally had a chance to question a suspect neighbor across the street who has a couple of dogs about outside water dishes which have a heater.  Sure enough, he had one behind the house out of sight and it was plugged in.  He was very cooperative in letting me walk though the house to look at this dish.  We unplugged it and I went back to the shack to listen for the noise, it was gone.  Mind you, when this thing was sparking it was S-9+ and wiped out 20 m for 5 or so seconds every minute, more often as the weather got colder.  Anyway once unplugged the noise was gone.  I said I'll buy you a new water dish if I can have the old one, he agreed, I did and it's now in use and the band is quiet again.  I have the dish in my possession and will take a couple pictures of it perhaps contact ARRL with the information.  These water dishes when in failure mode are like arc welders, yes, that bad.  How long it would have continued to work is unknown, it might last for years or stick closed or open the next day.  It's been a problem for the past few winters and to work around it I had a noise canx box, which helped plus If the antenna was pointed away from that direction it was less noise.  

Anyway for what it's worth the brand is K & H Thermal Bowl.  I have pictures if anyone is interested.  The bowl I purchased is the same brand and model.  We shall see how long it lasts.

Long story, sorry.
