I can't afford the hardware but
the GNU-Radio project is doing some cool stuff.
Like using a cable modem and an ADC to pull HDTV off the air.

from the web page--
"A software radio is a radio whose channel modulation waveforms are
defined in software. That is, waveforms are generated as sampled digital
signals, converted from digital to analog via a wideband DAC and then
possibly upconverted from IF to RF. The receiver, similarly, employs a
wideband Analog to Digital Converter (ADC) that captures all of the
channels of the software radio node. The receiver then extracts,
downconverts and demodulates the channel waveform using software on a
general purpose processor."
