Passive Aircraft Receiver

Passive Aircraft Receiver

This is basically an amplified “crystal radio” designed to receive nearby AM aircraft transmissions.
The “passive” design uses no oscillators or other RF circuitry capable of interfering with aircraft communications so it should be fine inside the cabin of the aircraft. Nevertheless, check the regulations before using this receiver on a commercial airliner. New security regulations probably prohibit this device on commercial flights. Do not expect to hear two-way aircraft transmissions with this receiver! It is a short-range receiver only.
