I'd like to adapt a simple $60 voice recorder to record my flights. From a little searching on the Internet, it looks like the impedance of the radio is 150-600ohms, but I can't find anything that gives me a figure on what the impedance of the mic jack on the voice recorder would be.
It seems most portable headphones are <75ohms, would that mean the microphone would be that as well?
The product I'm looking at is here: http://www.bestbuy.com/site/olspage...order&lp=3&type=product&cp=1&id=1218061082065
