>I prefer about 400 Hz, your preference may be different than this.

Dick,

What process did you go through to arrive at 400 cycles?

I ask because I'm relatively new to CW and have experimented with the 
available frequencies in the K3, and find that if the signal is down 
in the noise, that higher frequencies seem to jump out of the noise 
better. However if the signal is strong, I prefer lower frequencies 
such as 400.

OTOH, being relatively new to CW, I am open minded and defer to 
experience and would like to hear what you and others have to say on 
this subject.

73,

Paul
