Phil,
With 1 W drive I get around 25-30 W on 15 and 10 m bands and close to 50W on
20 m band from KXPA100

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.

This can be answered by reading the specs in the manual.

Has anyone used the new KXPA100 100-watt amplifier with other "simple"
QRP rigs? By simple I am thinking of as simple as the Norcal 40A and
maybe as complex as the Elecraft K1.
Two issues that I can think of:
1. RF Drive. Is 1 to 2.5 watts RF sufficient to drive the KXPA100
cleanly?
2. Key out. Most of these simple rigs (as far as I know) do not have an
amp keying interface. It would be nice if they did to QSK key the
KXPA100 (thus, driven by the rigs electronic keyer).
Is it hard to put a key output line in something like the Norcal 40A or
maybe the KX1?
Thanks for your comments.
