I'd like to know of any experiences (good and bad) regarding transmitter
hunting.  This past Sunday we had an impromptu hunt when an HT was
inadvertently keyed on the local wide-area repeater.  

It turns out that the HT was interfaced to a TNC and when power was turned
off to the computer, the TNC keyed the transmitter (which was on a power
supply).  The owner knew nothing of the problem and left his QTH to run (for
exercise).  The HT stayed on the air (keeping the repeater down) for ~2
hours.  This happened about noon.  

Once we got beam headings, three of us took off looking for it.  We
discovered the location in about 45 minutes, but had to wait for the guy to
show up.  It turns out that his VHF antenna was in the attic and that he
lived in an apartment complex.  Fortunately (for us) he had a 10 meter
dipole outside which helped in deciding what apartment door to knock on.
Upon his arrival he went upstairs and shut the thing down (finals were fried
by this time).  He also apologized profusely.  Anyway, it made for an
interesting afternoon.  We did all of our coordinating on 440 since the
three of us had dual band rigs in the cars.  

Suggestions are welcome.  I'll summarize all responses to the net.  

Tnx & 73,

Jeff
