[Elecraft] [K3} Mic gain/noise on xmit

[Don Wilhelm]

Mike,

That sounds like you have your MIC SEL menu set for "H" - try tapping 
the "1" button to change it to "L" so you can set your mic gain higher 
(and gives you more range).  I don't know if it will help your noise, 
but it would explain the difference between your setting of 9 and the 
other fellow's 30.  BTW, mine is set at 38 for the Elecraft MD2.

73,
