[Milsurplus] Noise question, not too far off topic.

[Jack Antonio]

I've been dealing with line noise here at my new QTH, which
has been keeping me off AM.  Since a  lot of my receivers do
not have a noise limiter, it is really a bother. Noise limiters do
make the noise slightly less annoying, and a blanker punches a
hole in the carrier, which is just as annoying as the noise itself.

I DF'ed the area it is coming from, reported it, and the power company
said they found bad lightning arresters and cracked insulators.  They
will repair it (hopefully pretty soon), but told me it is an ongoing problem
in this area.

So, the question is...

Does anyone have any experience with something like an MFJ DSP
unit as an outboard unit following a BC-348 or similar receiver, in cleaning
up line noise.  The noise waveform itself  is a sharp spike.


Thanks
