Aircraft Receiver - The Passive Aircraft Receiver 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 ....(electronic
circuit added 7/03) |

AM Receiver for Aircraft Communications (improved) - This receiver is controlled
by a Frequency Synthesizer Circuit. The receiver is VERY stable, low
noise-level and easy to build and tune......(electronic circuit added 7/03) |

AM-Receiver for Aircraft Communication 118.250MHz - The aircraft communication
in Sweden is still Amplitud Modulated (AM). The local airport (Axamo) use the
frequency 118.250 MHz. The reveiver I will explain is a tunable AM-receiver for this
frequency. The receiver is instead manually tunable with some 100kHz around the
118MHz. The output from the receiver is a low level output (100-200mV) so you must
connect it to some kind of amplifier. I will not explain how to build an
audio-amplifier....(electronic circuit added 4/05) |

Aviation Band Receiver
- Figure 1 shows a schematic diagram of the Aviation Receiver--a super heterodyne AM
(Amplitude Modulated) unit built around four IC's: an NE602 double balanced mixer
(U1), an MC1350 linear IF amplifier (U2), an LM324 quad op-amp (U3), and an LM386
audio amplifier (U4). In operation, an antenna that plugs into J1 picks up the AM
signal. That signal is then coupled through C1 to a three-section, tuned-filter
network consisting of L1-L5 and C2-C6.....(Tony van Roon's circuit added 9/04) |
