[Elecraft] KXPA100 with other QRP rigs...

[Phil Hystad]

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.
