After posting the question I found this on page 102 of the manual:
RTTY/Data Operation
Since some RTTY/Data mode duty cycles approach 100%, you should reduce
power to about 5 watts or avoid transmitting at 10 watts for longer
than 1-2 minutes at a time. (Power levels above 10 watts are not

All,
I was reminded that I should have added that CW and SSB are low duty
cycle modes while FT8 and several other data modes are high duty cycle
and will produce more heat.
The 'finger test' I mentioned is suitable for any mode.

Aaron,
I cannot give you a specific answer, but go by the heat.
I would suggest you first try 5 watts, and operate at that level for a
while (I suggest 10 minutes).
Then check the heatsink temperature - if you can hold your fingers on it
for longer than 5 minutes, then all is well.

What is the recommended highest power level for a QRP Elecraft K2 to
operate on digital modes like FT8, JT65 etc, without blowing the PA's?
