In North America, just buy an air-band radio and listen to Raleigh-Durham tower all you like, or if your ham unit receives the aviation VHF frequencies, do that. Or find it on LiveATC.net It's only illegal to broadcast without authorization, not listen in.

Digital is not always better. Digital modes have been created for amateur radio use; the amateur radio VHF 2m band (144–148 MHz) is very similar to the VHF aircraft band (108–137 MHz). I have a radio that uses both FM and a digital mode on the amateur 2m band. Here are some notable differences between FM and digital: When the signals are ...

This is the expected behaviour. The other pilot might make some sound or even talk to someone else. You don't want any noise interfering with your own voice during transmission. Two microphones picking up your voice might also decrease the sound quality because of the small delay between the two locations.

That‘s what is supposed to happen. The person in the right seat might be having a conversation with another passenger and you don’t want their conversation to be transmitted to ATC. Most audio panels also have a button that lets you isolate the pilot or crew from the rest of the passengers. I use that button all the time when on takeoff and landing so that ...

Why dont we ditch the old radio system full of parasties and use ADS-B instead for voice communications instead? Well, why don't we use televisions for washing dishes? Because televisions don't wash dishes. Likewise, ADS-B doesn't carry an audio signal, so it can't be used for voice communications. Perhaps ADS-B could be modified to carry voice signals, ...

ADS-B is very low bandwidth and is completely unsuitable for carrying voice traffic. The answer to the "why don't we" question is quite simply "it doesn't work that way".

As an additional point... the reason ADS was given its own frequencies was so that other communications would not interfere with the needed Position and Identification information sent out via that method. ADS can in many places surplant the need (though I'm not at all suggesting that it should do so) for primary radar. There are too many things that can end ...

So after Juan's help and also talking to Becker I think I've found the answer: It's an unlucky impedance combination. That means maybe I can get it to work by lowering the VOX-level (increase mic bias) far enough so my instructor can activate it but if I lower it too much, my own mic will constantly activate the intercom, resulting in constant noise. ...

Yes. The idea of listening to anything more than scratchy AM radio via your ADF was an alien concept in the 70s, unless you had some custom system made up for you. It's really only taken off since ANR headsets have made it quiet enough within the earcups to make music worth listening to. You just need to get a mono-to-stereo jack adapter to hear the mono ...

Please cite what (if any) ATC rules have not been followed. No ICAO recommendations were explicitly broken. Whether or not the local authorities require the pilots to read back a newly assigned radio frequency, I do not know, you will need to refer to the local laws to determine that. It is likely that reading back new radio frequencies is mandatory, but ...

While "comfort" may seem like a luxury, it's no fun to fly around with a headache. Give them a good try and look for minimal "squeezing" pressure. Also see other answers and comments re taking hearing protection seriously. Also if you routinely wear glasses (including sunglasses) be sure to test while wearing them-- they may break the earcup seal in a way ...

This answer is slightly offtopic for the aviation bit, but I believe it is useful to answer the question. Marine VHF at 150-ish MHz is a local radio technology. It reaches the horizon, no further. With an aircraft, the horizon can be hundred of miles away, due to the height of the aircraft. At 10000 m height, the horizon is approx. 350 km away. At 40 m (a ...
