It's ALL good! I used the milivolt setting on my DMM, and really fine tuned C9 for the null which is really sharp. Now the power meter is reading correctly, and I am good to go.
I will be heading to the deck tonight to toss up my end fed antenna, and give it a whirl. My CW is pretty rusty - but if you are listening on 40 near the QRP calling freq - and have patience, I would love to work anyone out there! Don, thanks so much for all your help! The KX1 has been a really fun little project, and I hope to build more Elecraft kits in the future.
