[RFI] Poor man's portable spectrum analyzer

[N2TK, Tony]

Yeah, it is weird that when I sweep the bands there are only 3 frequencies, all in the lower 160M band that are affected. Next step is to go beyond about 2 blocks in the westerly direction.

Dusk to dawn may be a defective street lamp.  It fails to start and repeatedly retries from dusk to go dawn.  Usually, however, the raucous noise covers many bands, not just a few frequencies.

Subject:[RFI] Poor man' s portable spectrum analyzer

 

Looking for something portable that would show the spectrum 160-2M with some
kind of small loop directional antenna. The purpose is to walk the
neighborhood looking for noise sources. I had used my car AM radio to track
down a bad wideband noise source that turned out to be a leaking transformer
about a mile away. It was quickly replaced.
 
I have a dusk to dawn noise source that is on 1817, 1825, and 1828 only. I
have been using my Tecsun PL-880. So far I got the general direction and
have to go farther out at night to try to find it.
 
Because of these type of noise sources  I was wondering if there is
something available other than the $1K high end portable spectrum analyzers
that I could use to walk the neighborhood looking for noise sources that
affect the Ham bands?
Tnx for any feedback
N2TK, Tony
