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.
