Fox Fined For Using EAS Tone In Football Ad

The Boy Who Cried Wolf is a simple parable that teaches children the fatal risk of raising a false alarm. To do so is to risk one’s life when raising the alarm about a real emergency that may go duly ignored.

Today, we rarely fear wolves, and we don’t worry about them eating us, our sheep, or our children. Instead, we worry about bigger threats, like incoming nuclear weapons, tornadoes, and earthquakes. We’ve built systems to warn us of these calamities, and authorities take a very dim view of those who misuse these alarms. Fox did just that in a recent broadcast, using a designated alarm tone for an advert. This quickly drew the attention of the Federal Communication Commission.

Fox Hunting With A Raspberry Pi

No, not a real fox! [KM4EFP] is a ham radio operator with a passion for fox hunting, which is an event where several radio operators attempt to find a broadcasting beacon (a “fox”) using radio direction finding techniques. [KM4EFP] has just built his own portable fox using a Raspberry Pi in a very well-built enclosure.

Since the fox could be outside for a while, the project was housed in a reasonably weatherproof ammunition case. A mount for an antenna was attached to the side, and it is hooked up to a GPIO pin on the Raspberry Pi. The entire device is powered by a 6000 mAh battery pack which allows the fox to broadcast long enough to be found.

The software running on the Raspberry Pi is very similar to the Pi FM transmitter program but it is specially made for ham radio broadcasting instead. Almost no extra hardware is needed to get the Pi broadcasting radio, as these software packages can drive the antenna directly from the GPIO pin. This is a great twist on the standard FM transmitter that ham radio enthusiasts everywhere can use to start finding those wily foxes!
