Recording ATC audio with Sony ICD-PX232

Hi all,

Recently I have started to record some of my flights using a GoPro, and recording ATC audio using a Sony ICD PX232 which is hooked up to my headset using a splitter. The issue is the clarity of audio when I speak, it's very distorted though you can make out what is being said. Audio coming in from ATC and all chatter on the radio is very clear.

I have the cable going into the 'Mic In' jack, there's also an 'Audio In' jack which I haven't used.

If anyone can shed any light on how to get my audio clearer that'd be much appreciated.

Many thanks,

Why are you not recording the audio on the GoPro?

I'm not familiar with the equipment you mention but you are likely better using the high-level input than the mic input, which is easily overloaded. If the radio sidetone (your own voice) is clear in your headset, your recorder might be suffering a bit of RF feedback when the transmitter is keyed. If a change of input, or using the GoPro as suggested above doesn't work, there are various location, filtering and grounding fixes which can help with RF pickup. Out of interest, are you flying a metal or composite aircraft?

Sounds like the peak voltage is oversteering the audio input = isnogood for the electronics.

Does the 'splitter' have connections to both the headset 'mic' and 'audio' jacks?

If so, disconnect the 'mic' one

It should still record your voice via the intercom, and whilst transmitting, via the sidetone.

Insert here a paragraph explaining that in the UK it is actually illegal to record and replay Air Traffic Radio messages (Wireless Telegraphy Act) :-)

I understand that in other countries it is not illegal.

more info from LiveATC FAQ - Frequently Asked Questions | LiveATC.net

It is illegal to provide air traffic control feeds from within the UK due to an outdated law that originated back in 1942. The antiquated law states that although it is not illegal to sell, buy or own a scanning receiver in the UK, it must only be used to listen to transmissions meant to be broadcast to the general public.

OfCom (the U.K. regulatory authority for communications) has stated on numerous occasions: "It is an offence to listen to any other radio services unless you are authorised by a designated person to do so."

This means that it is illegal to listen to anything other than general reception transmissions unless you are either a licensed user of the frequencies in question or have been specifically authorized to do so by an authorized person. This is clearly a law that needs to be updated in light of the many educational uses for listening to aircraft communications. Furthermore, the original reasons for this law have long since become irrelevant.

Let's hope this law gets modified - there has been at least one online petition aimed at attempting to get some attention but it does not seem to have had much of an effect on Ofcom. If you are a UK citizen, please contact your MP and see if they can help make an exception to this law.
