I would have an interest in this, I think - depending on what it is scheduled against.
I was a licensed Amateur Radio Operator in the USA - callsign N6PNL - and had even taught theory classes back in the early 1980's. It is a time-honored way to learn about the basics of Electronics, and many an Electronic Technician and Electronic Engineer has learned his skills for employment this way. It was something which had fascinated me as a kid, from the mid-1960's.
...But alas, I am no longer a licensed "Ham"; after renewing my license once, I let it lapse in 2008, for a variety of personal reasons.
I would STILL encourage those who are curious to explore the hobby, though. It is international in scope, is of VITAL importance as a communications medium during Natural Disasters, and is often the only link to the outside world from less developed countries. "Hams" serve as technological ambassadors, and of course are still important in advancing the State of the Art in Telecommunications and Electronics - and even in Physics.
For all of these reasons, most countries have a special clause in their telecommunications regulations, allowing amateur radio enthusiasts to experiment and practice their hobby across reserved radio bands, using "home-brew" equipment, rather than the equipment required for the tightly regulated commercial radio services, which are restricted to fixed-channel frequencies and limited emission types and modes. Ever wanted to bounce a signal off of the moon? Ham Radio Enthusiasts have done this - even built their own satellites, which have been launched into orbit!
AnthroCon has had a radio "Fox Hunt" most years since moving to Pittsburgh. Such Fox Hunts consist of a low-power transmitter hidden somewhere about the premises, usually disguised as a mundane object, which transmits a weak-but-distinctive signal for brief intervals. It is the job of the "hunters" to track down the "fox", usually with hand-held equipment and home-designed directional antennas. Much like what naturalists and Park Rangers use, to track wildlife equipped with radio collars. Prizes may be awarded for First hunter to find the fox, second hunter, and so forth. And other than the owner of the transmitter, you do not require a license to participate in the hunt!
