Hello everyone, I'm currently assembling a KAT1 for use with my already-completed K1-4 (which I'd previously been using with an external tuner), and I'm having some trouble with the final step of the SWR bridge adjustment of trimmer capacitor C9. I did verify the previous steps of setting power output to 5.0 watts, attaching a suitable dummy load (same QRP dummy load I used when aligning the K1), setting both variable resistors to 60% of their travel, setting the tuner menu options to 'QLS', then entering tune mode and measuring voltage between TP1 and the ground jumper.
[The problem:] But I'm getting 0.0 VDC across TP1 and ground. I did remove the KAT1 board and triple check all solder joints, as well as checking for continuity through my toroid windings. I also checked to make sure that power was reaching the KAT1 board by measuring about 5.5 VDC across C17 ... plus the fact that the tuner is 'recognized' by the K1 and all of its menu functions check out as normal. Does anyone have any tips on something else that I might check, or could it be that I've actually got a bad trimmer capacitor? I was unable to find any similar descriptions here. Thanks for your time, everyone. I absolutely love my K1 and can't wait to have it be even more portable with its new ATU.
