As Dave Leeson points out, the ideal receiver to track noise is an AM
VHF handheld.

Of course, most hams have ready access to 2 meter FM transceivers, but
these are nearly useless thanks to FM's inherent noise rejection.

However, recent handhelds also include a receive capaility on the
aviation bands. Aviation radios transmit on AM, not FM, so the
transcievers automaticaly switch to AM reception in those bands.

So if you are tracking a noise source, set your transciever to a
frequency somewhere around 123 mHZ - any empty frequency within a mHz
will be fine - and go hunting. Good luck.
