[Elecraft] KXPA100 with other QRP rigs...

[Phil Hystad]

Yes, but that does not answer my question.  I could have been more clear I guess.   I am thinking that this 3.5 to 7 watt range is to achieve 100 watts output.  I am asking about, say, 1 watt drive and certainly I expect the output to be lower.
