[Elecraft] KX1 RF Power Question

[Craig Miller]

I just finished adding the 30/80m module to my KX1 which has the KXAT1 ATU.
While adding the 30/80 module I also installed the output power fix
involving the two resistors in the driver/final.  The unit seems to work FB
but the output power is a bit lower than I expect.  I measured the output
power with an N8LP LP200 power meter on all four bands with a dc supply
voltage, measured during transmit by the KX1 "bat" function of 11.9 - 12.0V.
I made the measurements without the atu installed and also with it installed
and in tune position.  All bands showed SWR=1.0.  My question is are these
readings reasonable for these conditions?

Freq.    No ATU    w/ATU
3.55     1.57W       1.02W
7.02     2.84W       2.72W
10.11   3.57W       3.36W
14.05   2.83W       2.74W

Any ideas/suggestions would be greatly appreciated.
