[Elecraft] Microphone suggestions for K3

[Bob McGraw]

I've been using the Shure SM-58 for years and on several different 
radios.    It has a nice flat response between 100 Hz and 1500 Hz to 
cover the primary voice frequencies.  At 1500 Hz there is a gradual rise 
of 6 dB peaking at 4 kHz to enhance the mid-range, followed with a rapid 
roll-off starting at 5 kHz continuing on to 15 kHz.   The low end has a 
natural 8 dB roll-off starting at 100 Hz continuing down to 50 Hz and 
lower.   The frequency response is tailored for vocal use with a 
brightened mid-range and a low frequency roll-off.   The polar response 
is Cardioid having very uniform sound rejection off of the back side.  
Also it has an excellent pop filter for excellent close talking 
utilization eliminating all but the worst pops of P's and huffing of 
H's.   It is easy used in both balanced input and unbalanced input 
configurations.

Just and old deaf recording engineers perspective of a very rugged good 
sounding microphone.
