Funk Amateur Vector Antenna Analyzer

Recently I purchased a Funk Amateur FA-VA4 kit. I wanted something a little more capable than my MFJ-259B without spending many hundreds of dollars. I'm sure there are much better analyzers but for $120US the FA-VA4 gives me the impedance measurements, SWR sweeps, etc. that I wanted without breaking the bank.

Although this is technically a "kit" most of the board comes pre-built. You only have to add some display connections, a switch, the BNC jack, and the battery holders. It's an easy build and worked right away.

FA includes a set of connectors to use when self-calibrating the analyzer. They refer to this as a SOL procedure-- S)hort, O)pen, and L)oad. It takes a few minutes but the only thing required of the operator is to switch connections when prompted.

All-in-all this seems to be a nice addition to my test bench.

Missouri SOTA

On December 16, 2017 Woody WD9F and I journeyed to Taum Sauk Mountain and Knob Lick Mountain in Missouri for a little SOTA activity.

I was operating my Elecraft KX-2 and an end fed wire with a 9:1 unun. Power was an external Bioenno Power LiFePO4 battery.

It was a great day with plenty of sunshine, light winds and temperatures in the mid-50's. Had a great time with plenty of contacts. Many thanks to all the chasers!
