https://stream.echo6.co/videos/watch/6ec668f4-51f5-4a3e-b541-ca1991b740c0 A 'wide as barn door' but deaf receiver that picks up everything at once. High gain audio amp, diode and short whip. I pick up RF noise, AM broadcasters and even airband while near an airport. Idea from http://www.techlib.com/electronics/allband.htm Or, if you want just airband reception, build this http://www.techlib.com/electronics/aircraft.htm Possible modification: Potential to make it an audio induction loop receiver. Increase the 1n capacitor in the base of the transistor to 100n. Solder that to the free end of the RCA socket. Change the connections of the switch so it just switches the telescopic whip in and out (ie not to socket). Add a 10 uH coil on an RCA plug. You may be able to hear audio from hearing loop equipped buildings etc. Also other buzzes and noises.
