I have seen that when you need receive very weak signals, signals improve a
lot with AGC THR set at 15 (usually for a more silent reception I use THR
7).

Duane,
important is to set fine tuning (1Hz) when using the APF as the only precise
tune on spot will effectively pulling out this weak sig from the noise. I do
not understand why the K3/K3S never got as same feature as KX3 > switching
to fine tuning automatically when APF is ON...
Also try to
I use an audio spectrum display - Spectrogram - to fine tune a barely there
weak signal. Set tuning rate to 1 Hz - the APF peak is less than 10 Hz. Set the
frequency cursor in Spectrogram to your pitch frequency. Set the DSP bandwidth
wide so the NR works effectively ~ 700 Hz. Use NR mode ~m5-3
Use DUAL PB, it will shock you at how clear an almost unreadable CW
signal becomes...

Would anyone be willing to offer suggestions/recommendations?
Your setup of the K3s to maximize weak signal cw reception?
I especially would like to figure out how to maximize the APF without ringing.
Sincere thanks
Duane
