One caveat here... if you happen to set the ALC levels for low freq 
tones, say 600 Hz, then end up using 2150 Hz, that level may very well 
be well off, overdriving or underdriving while the radio tries to 
compensate with varying power levels or accidental distortion.  So one 
should be cautious of that or ALWAYS use the same tones.

I've made that a non-issue for RTTY by using FSK but in PSK (sideband 
doesn't matter) or others, the same issue remains.
