I was inspired by Bob W3BBO's success in completing his 20 Meter QCX+ kit. So much so, that I am going to start my 40 Meters QCX kit that has been sitting in the shack for over a year now. But before I begin that, I wanted to get my O'scope completed and running. Mr. Procrastination (yours truly) started this a long time ago. I only had a few components left and decided to finish it today.

The only thing I had to solder in today were the slide switches, the signal input jack and the headers on the LCD Board and on the main board. When I got to soldering the headers on the LCD Board, I came to realize I was shorted two male 2-pin headers in the parts count.

So what do you do? You go to the junk box, of course! I had a spare six pin header that was extra and left over from some previous kit, and I was able to break off two 2-pin sections, trim them to the proper length and install. Worked like a charm!

Another lesson learned ...... don't EVER throw anything extra away. You never know when it will become useful.

One thing I noticed though. In the testing procedure, you are asked to measure for a test voltage at a test point - and then, if it reads OK, solder a short on two points on the board.  How come I can make a solder bridge when I don't want to - but can't seem to WHEN I HAVE TO?

I ended up soldering a discarded component lead across the two solder pads in order to create the necessary short.

With this little kit completed, I think I will start inventorying parts on the QCX tomorrow night. I think I have enough egg cartons to hold everything.
