[Elecraft] K3: cw man has microphone question

[DOUGLAS ZWIEBEL]

Okay...all this microphone talk piqued my interest (yes, that is
spelled correctly).

I bought my mic long, long ago.  Back then, as I recall, Heil only
offered one element in a boom.  I have the BM10K (just the boom, not
the headset).  I opened it up today and note that the element is an
HC5.

I see that the specs are:

HC-4 Specifications:
  	Type: - Dynamic. Copper wound bobbin, moving coil transducer
  	Frequency: 500 Hz to 3,800 Hz with 10 dB rise at 2,000 Hz.
  	Sensitivity: -66 dB Nominal
  	Impedance: 2,000 ohms @ 1,000 Hz.
  	Size: .530 x .850 x .310

HC-5 Specifications:
  	Type: - Dynamic. Copper wound bobbin, moving coil transducer
  	Frequency: 350 Hz to 4,000 Hz with 6 dB rise at 2,000 Hz.
  	Sensitivity: -68 dB Nominal
        Impedance: 2,000 ohms @ 1,000 Hz.
  	Size: .530 x .850 x .310

Not much difference, but two questions:

1.  Can you actually hear a difference, and

2.  With the K3, does it matter since there is an 8 band EQ on tx?
Could one tailor the an HC5 to "sound" like (close to) and HC4 or
vice-versa?

Thanks...
