I was inspired to copy W1GHZ’s power meter from April QST (pg 52). Seemed like it would be nice to know if my 10GHz rig (or any of them!) was putting out power. Got some bargraph boards from him, the rest of the parts from the internet, and finally built it today.

I had a bit of trouble cutting a square hole with only a hand drill, but I can see the bars. (If anyone likes designing and printing cases, let me know!)

Turns out I don’t have any 9v batteries, so testing will have to wait until I go to the store. I don’t expect to have any problems though, since the bargraph circuit is pretty simple, and the AD8317 board had everyone on it already.
