[TenTec] CW Audio tone

[Richard Detweiler]

Hi Bill and all,

I will second your statements here,  I also use very low audio tones.

about 250 to 350,  and 350 to 500 for a casual chat.

If I may add this.  I think the big reason for using lower tones is that the 
static at the frequencies above 500 hz seem to be more annoying to me.  It 
just seems to get in the way of the signal.  So a noise floor signal is more 
readable if i'm not distracted by the noise.

Also, I could be wrong, but I think the Lower frequency tones has more audio 
energy.
