[OT] Locating source of FM radio interference

[Bayard Coolidge]

If I were still up in the GNH area, I'd offer to come over and help you
out. But, I suspect your best bet would be to find a local amateur
("ham") radio club and see if they have some folks who could help you
triangulate the source. It can get into a real can of worms - two
otherwise innocent stations transmitting at the same time might have
their signals "mixed" by a dirty pipe joint or a stray diode, and emit
spurious signals at their sum and difference frequencies (aka intermodulation).

It's also entirely possible that there is a "pirate" broadcaster - i.e.,
someone who's decided s/he has something to say to the world, and
FCC regs be damned. What they don't understand is that when they're
caught, they might get off with a warning, but could get a $10,000 fine.

If none of the hams on the list (and there are a couple :-) can help
you, contact me offlist and I'll try to conjure up some resources, even
though I'm in South Florida these days.

Something near our house has recently started
generating spectacular amounts of radio intereference
that's most noticeable around 89MHz.  I have no
portable radio equipment of any kind except a humble
little $10 handheld with a normal telescoping antenna
that seems not to be very directional, or at least I
don't understand its directionality.  Is there some
way I can use it to do some sort of triangulation on
the source of interference?  Maybe some particular
way of holding/orienting it, or selectively/partially
shielding it, or tuning it, or...  ?
