Bruce,
What happens when you try it into a dummy load? What is the power
indication and what is the SWR indicated?
Put it into ATU CAL and try - what are the results?
Then put it into ATU TUN and try again - results?
Are resistors R3 and R4 swapped?
Remove the KXAT1 and measure the resistance between P1 pins 1 and 3 - it
should be zero.
Then put the KXAT1 back in and measure the resistance between the BNC
jack center conductor and lead 6 of T1 (the 1 turn winding) - you should
measure zero ohms if the connectors are mating properly.

My KX1 seems to be working fine; I hear a strong signal into my other radios
and no error messages or other problems. When I install the ATU I can null C9.
When I tune, power always reads 0, sometimes for a second 1; R always equals
9.9. I am feeding to resonant antennas, a dipole on 14, an end fed on 7. R4
is at maximum. The same thing happens with the internal batteries or with a
13.5 power supply. I have checked my connections, soldering and toroids
several times. Any suggestions would be very appreciated. I do not have a
wattmeter or an swr meter. Thank you!
