Oh great - the HD Radio Alliance can track what is listened to - need
to get this one to the press ASAP !
Sounds like a paranoid fantasy. How is the information going to get
back home? Via the power lines if the HD radio is plugged in? Via the
FCC part 15 "transmitter" associated with all powered receivers? That
seems impractical
The Brits used to send around vans to detect TV receivers in the
possession of people without a TV receiving license.
