More ideas for projects (some not so simple):

60kHz receiver with loop antenna to pick up WWVB and phase compare to
	your local frequency standard.
Multiple antenna interferometric receiver setup for radio astronomy
	(could be UHF or VHF for simplicity). Jupiter, I understand,
	is a relatively simple target.
X band Gunn diode oscillator frequency modulated to make simple radar
	for displaying local weather on Plan Position Indicator
Doppler radar for measuring the speed of passing cars. (My 11th grade
	science project was one of these. Interesting.)
Optical communications link using visible/IR LEDs for short range or
	laser diodes for longer range. Simplest would be to transmit
	audio, more challenging would be to transmit RS-232 computer
	data or video. Could investigate error detection/correction
	algorithms and hardware.
Low power, unlicensed (see Part 15) VLF communications system with
	loop antennas.
Seismograph.
Passive IR alarm system.
