[Elecraft] K3 - Proset K2 Mic Frequency Response

[Jim Brown]

Frequency response curve looks reasonable for a communications mic, but 
at what distance was the curve run?  And what fundamental microphone 
types are these mics -- omni, cardioid, hypercardioid, supercardioid, 
bidirectional? VERY important. 

Anabolic is a new one one me too!  :)  Most microphone measurements are 
done in anechoic chambers. 

I'm saving a copy of that graph to use in my lectures!
