[Elecraft] K3 - Audio/IF filtering definitions

[Rick Bates]

That's a key point as not everyone understands that less audio is better on
PSK and most folks tend to hit the audio hard on both TX and RX.  The
resulting IMD is shown as 'echoes' on the waterfall and it tends to bang on
the soundcard AGC, potentially blocking the signal you want to hear.

For non-Elecraft gear, adjust to *just* when the ALC is starting to get
tickled, then back off a titch.  For Elecraft, make the fifth ALC bar blink
(this changes with the actual tone used) and go no higher.

Of course you can use the data modes with the K(X)3 instead.

With this narrow bandwidth 
I find it easier to pull weak signals out of the noise floor and 
avoid overload from nearby strong signals.
