You using the main ae for rx ? perhaps a small loop would be better ?
Yes, and normally this is no problem (a 20dB attenuator takes care of
all IM problems). I have a small portable loop that can be tuned to
500kHz and QRM is as band as on the big antenna unless I null it out
with the loop. Unfortunately the null is east-west so when nulling
out the QRM source I null out south UK too ...
Last night I took a portable AM radio to locate the QRM source and
found out that it was a 12V dc "electronic transformer", also running
quite hot. It has been there also in May (when I didn't have that
QRM) so it must have gone faulty some way since then. I am going to
replace it by a good old fashioned 12V dc power supply.
