In off-list email, Kelly has said he thinks is noise is from a grow
operation, so I think he has to DF it on the HF band(s) where he hears
it. That means loop, so something like what W0IVJ has posted is probably
the way to go.
Another important suggestion -- a spectrum display is usually the best
way to nail down whether it's impulse noise or electronic noise, but I
don't think Kelly has one.

I DF up to 950 MHz for two reasons. One, small directional antennas, two,
they usually aren't needed because as the frequency goes up, the distance
goes down and you can usually narrow a source to a few feet at that
point. What kind of VHF and UHF equipment do you have that can receive in
AM?
