[Elecraft] [K3] K3: CW weak signal

[Gary NL7Y]

Low band DX from Interior Alaska are always a work in progress. Ignore the
howling and instead listen for the signal. It's not a wolf at the door. Try
this for weak DX:

200Hz filter (or the narrowest you have)
6-8db filter gain (weigh S/N vs signal strength - I set mine at 8db gain for
weak, lower for stronger)
BW 100-0.50 Hz (any wider is worse for weak signals for me)
Pre-Amp on (it does help and does not distort the signal)
NB as required (I need DSP 2-7, IF Med-7, = 2S units lower city noise)
AGC Threshold 006 for weak signals, 005 for stronger signals if AGC on
AGC Slope 000, 005 for stronger signals if AGC on
Also try AGC Off and ride the RF gain for best signal 
Adjust audio gain for minimum noise/best signal

You truly haven't experienced the unique abilities of the K3 until you work
Low Band DX in, or just out of the the noise floor, compared with other
radios. It's an amazing piece of radio gear.
