[RFI] Poor man's portable spectrum analyzer

[David Robbins]

I use a grundig g5 sw/fm receiver.  Has nice directional pattern on the low bands, can follow a null right to a source with it.

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.

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
