On CW, key down is PEP. On CW, carrier=keydown=PEP

On SSB voice, PEP and average power have no fixed 
relationship at all. In a solid state amp PEP SSB power it 
often is limited by linearity. SSB PEP is often actually 
less than CW or other modes where linearity isn't an issue. 
Unless of course the power supply or heatsink is the issue 
limiting CW power.

"Key down" is a pretty bad phrase to use anyway. Better to 
say what we actually are describing, like "CW",  "carrier", 
"RTTY" or "SSB voice", or whatever.
