It has been there for years, but isn't really a problem until someone happens to be on that frequency and you want to talk to them. Like this morning when FO8RZ was working up 1 from 28.002 and with the receiver set on 28.003 I had the pleasure of listening to this repetitive tone until I worked him :) 

So what the heck is it??  Obviously local, it is always there and never misses a beat.  I have pulled the big switch and listening with a battery powered rig, it is still there.  I assume some consumer product uses 10 meters for some unknown purpose...ever encounter this Elecrafters?
