The ones I enjoyed the most involved an unknown frequency, unknown
locations, but a quasi unknown time transmitting where it chirped, so
the first thing you had to do is figure out the timing duration and
frequency before you could do anything else. Then it was
rush-like-hell to a second location to capture a second chirp to DF
to get a little closer, and then spiral in on the fox.
I also liked the ones where we started 10 miles away from the fox,
but each time the fox transmitted the power levels dropped so you had
to move fast because you only had a 4 hour window or less before the
fox died as the power level dropped to the noise floor.
The ones that started on an HF frequency where loads of fun where a
helium balloon was used to hold up a long wire antenna for the first
hour, then the balloon would get released, and the fox switched to a
different transmitter, on a different frequency, and then an hours
later another switch, and so on.
The losers bought dinner and/or movies for the winners, and the
winners got to help the hunt masters (or game warden is you will)
plant the next fox.
I never had any interest in the building and planting the fox, but
enjoyed the hunt more then anything else, especially when it you
could not use radios for communications and had to sneak up on the
fox from some distance away.
I don't recall any of the foxes being more then a couple of Watts,
and recall that the best ones would drop below 100 mW by the time the
hunters got within a mile, and under 10 mW within a quarter mile.
