[Elecraft] SSB Drive

[Stewart Baker]

Hi David,

It is my experience that to use Yaesu mics with the K2 you really need a pre 
amplifier, either internal or external. I have an internal one built on a small 
piece of perforated board, and mounted on the mic jumper block.
It gives me enough gain for my MD-100 desk mic, and MD-31 hand mic.

The flat audio is probably because of the excessive low frequency response in 
the KSB2. It can be cured by reducing the values of the coupling capacitors.

I you look on my site,  you will see details about how to cure both problems.
