[Elecraft] K3- audio balance and hiss

[Don Wilhelm]

Mike.

Look at the post to the Elecraft reflector by W4TV Joe Subich two days 
ago.  If you want to emulate the audio response of other transceivers, 
use the RX EQ as he describes and you can have either a 3dB of 6 dB 
rolloff in audio response.
The K3 audio response is quite flat out to 4.2 kHz.
