Many cavers are also hams. We use 2M HTs for communication on
the surface when project caving in Sequoia and Kings Canyon
national parks. The WA6BAI repeater lets us coordinate with
people in Fresno from near the cave entrance. We can let the
cook know how many people are planning to come for dinner.
Over half of the NCRC cave rescue instructors are hams. Ham
radios have been very useful in some emergency situations. For
example see the President's Letter in: <http://wvara.org/het/Archive/heterodyne-2014-08.pdf>
We have also used QRP 80M radios for cave to surface
communications. The radio in the cave had two random wire laid
on the floor of the passage actin as an antenna with a tuner.
This setup let us coordinate a cave radio demo showing how to
locate the surface location directly over the transmitter in the cave.
More information about cave radios is in the back issues of

Many of us combine our affinity for radio with other activities
we’re equally passionate about — perhaps more. An obvious
example (one that renders this post marginally non-OT) is
hiking / camping; for some of us, it’s a natural environment
for small radios and big ambitions.
What are your ham-activated avocations? Do they come with
as-yet-unsolved problems in the field of radio ergonomics?
Where is the boundary between communications media and the things you most
enjoy talking about?
