|What is going on?
Back in November 2017 I ordered and built the Funk Amateur FA-VA4 antenna analyzer kit
. The kit was built and passed the smoke test without issue. I then went through the calibration process and it was successful (so I thought). I was not able to get the unit to work and I felt it was due to user error and tried to run the calibration again but without success. No matter what band I checked the SWR was off the scale. I even connected the device to a dummy load without success. I read and reread the manual and even checked out some YouTube videos and was just getting more frustrated so I was thinking of selling it to someone who knew how to operate the unit. As I watched more Youtube videos it seemed like a very straight forward unit to operate. Over the course of a year or more, I picked up the unit and tried to figure it out but just could not.
This past week I picked it up again and was looking it over but in so doing for some strange it occurred to me to open up the kit and look over my work. It's embarrassing to say but as I looked the board over I saw that the female BNC connector I did not solder the BNC center pin to the PCB board!!! I soldered this pin, did a reset to the unit and then ran the calibration again BUT this time the calibration took a lot longer. Once it was done I connected it to my Endfed antenna and checked 15m this is a band that I know the SWR is decent. Low and behold the unit worked as it should way back in 2017!! I just can't believe that I overlooked the obvious to open the kit up and have a look around. I now get to discover this great unit that I built years ago.
