Re: Radio interference on new install.
Ted,
Don't know if you've tried these yet, but here a few suggestions that pop
in my mind:
Isolate each transformer and see if the interference is one or both of
them. The irradic on/off action and the report about smoking remind me of
something I observed once. I've seen electrode connections that appeared
really well-twisted together actually make a bad connection. It would
"smoke" briefly, and eventually the heat (arc?) seemed to weld the
connection together (making a good connection), though this was not
visible at all upon inspection. It ran fine after that. I have no good
explanation, other than some sort of coating/corrosion on the wire, or
perhaps a conductive contaminant?
If you suspect anything like this at all, you might try lightly soldering
each trode connection. I do this on occasion when I suspect lots of
humidity/corrosion (like a place down on the river here in Austin) . I
use one of those little butane soldering irons, and just do the ends -
leaving enough wire to allow easy replacement if needed.
