[Elecraft] mic

[Jim Brown]

True "noise cancelling" mics sound awful. They work on the principle of 
cancelling noise more than an inch or two from the mouth. SUPER noisy 
places like aircraft are the ONLY place to use them.

Most hams who have too much background noise either don't work the mic 
close enough (it should be an inch or two above and alongside the 
mouth), or have processing and/or mic gain turned up way too high.
