I've heard some crazy RT from some ATC ground controllers in JFK recently, castigating people for not getting rapid fire multi instructions right the first time, when English isn't their native language.  Its quite disparaging, and like my kids, always somebody else's fault/problem, but typical New York. I'm going back there in a fortnight, wondering how I can record it cleanly. I tried using my iPhone and the cockpit speaker, but there is an underlying airframe whoosh sound that I want to do without. Can anyone suggest a way I can easily record what I hear in my headsets, a jack that allows pass thu, that I can plug ideally into my phone, as whilst this is a project, it is only a small one and I don't need to throw a lot of money at it. Thanks in anticipation.Tony Renshaw

The easiest way is to stick an electret microphone inside the earcup

with some glue or tape, and use an ordinary digital recorder. I've

done it this way for years and has worked flawlessly. Since I fly many

different aircraft as an instructor I don't have the luxury of

modifying the intercom system. One time I tried tee-ing off the

headset audio line, but the impedance mismatch required some extra

circuitry, so it became too complicated.

I have had very good success with a pair of tiny microphones placed in my Bose A20 noise canceling headsets (in a very noisy aircraft) plugged into a gopro camera,  as can be seen/heard in a YouTube flick I posted:

Part number is SP-BMC-2 as purchased online from http://www.soundprofessionals.com

I prefer the mics over plugging directly into the intercom, as one still gets some engine noise background for context.

Cheers, happy new year and good luck,

Hi Tony  

   

Why not make up a jack to plug into the jump seat socket and leave your headset out of the equation.  I saw it done on a 707 using a cassette tape recorder.  No idea what sort of voltages would be involved.  

   

Regards

I think Pete has the answer, using a spare headset jack point. Since they are not my headsets, I can't mess with them, I'll need another solution, but now I just need to go from a headset jack into a more conventional audio input to a taping device. Getting closer, thank you all.

Aircraftspruce sells these splitters and adapters. I've tried them in

the past, and the impedance mismatch resulted in poor signal quality

unless the output volume from the intercom is adjusted to be just

right.

Gidday Andrew, 

Thanks for the advice. I won't get those ones then. I might actually have something back from my old harmonica playing days that might just do the job, it's just I'm 7000 miles from home. I'll check as soon as I get home though. Thanks again.
