Thanks for everyone's input. After two months of this interference, it has
just moved and is no longer a problem for the channels I need to use. So,
although it is still present, I no longer need to locate its source.

You know those old WWII movies where you see German vans with DF eqpt
driving around trying to locate spies? Turns out they were HF units.
But,
it took three of them, in widely separated locations acting in unison to
get
the job done. And, the triangulation wasn't precise. It took lots of
time
and effort to narrow in on the general location of a spy sending.

combine an hf loop, with aprs, and you'll be amazed how effective it is.
aprs will allow your hounds to share their info easily.
you get the location of the other stations, on a map, plus your own, and
all
the bearing data.
