I am an extra class amateur radio operator with callsign NT4TN (as the domain name says).
Decades ago when I ran communications for a municipality in Florida I worked with
amateur radio operators in the context of disaster recover and preparedness.
I was impressed by the ability of radio to communicate across long distances
with either minimal infrastructure (which could be easily replaced if
destroyed) or no infrastructure at all.
Of late, I've mostly been interested in communicating by
bouncing signals
off the ionization trails left by meteors (image of some contacts I've had on
the 2 meter band) and other weak signal propagation modes.
I also enjoy racking up contacts all over the world, communicating without
any intermediaries via
ionospheric skip
and collecting operating awards. I've communicated with over seven thousand
other stations across 173 DXCC entities (a country or isolated geography).
The furthest contact I've made— at a distance of close to 12,000 miles— is
the Crozet
Islands, a sub-Antarctic archipelago which is uninhabited except for
the dozen or so researchers stationed there and an uncountable number
of penguins.
