Hello. I'm having problems with my aquarium heater and I was wondering
if anyone might be able to help. During the heater on/off transition stage,
the heater not only makes static noises which I can hear, but it also
creates some high frequency interference that disrupts the reception of
my AM radios. This happens on my stereo that plugs into the wall and
on my portable that uses batteries so it must be in the air and not
in the house circuit (ie. plugging the heater into a noise filter which
then plugs into the outlet would not help. I've tried that too actually,
and I was right, it didn't stop the static) I've had this problem for
a number of years actually, I finally couldn't stand it anymore earlier
this year and I replaced the heater with a new one. Then came summer and
the thing didn't have to go on anymore. Now that it's getting cold
again, the heater is being used and the static on my radio is back.
Argh! Anyone else have this problem? Anyone found a solution for this?
Thanks in advance.
Thomas.
