My schematic is a bit different than the one outlined in the video. There is one capacitor that is supposed to be in series with the antenna. I simply forgot to install that, so I just removed it from the schematic altogether. Below is a picture of my crappie schematic.
I think the most complicated part of this was trying to get everything mounted and fitted into the box. The holes drilled for the antenna and switch seemed ugly to the eye but work. I had difficulty getting the switch to fit properly, so I made the hole larger with a pair of wire clippers.
The whole circuit is wired into the meter inputs via a switch. The switch gives you the ability to turn the Signal Strength measurement ability on or off, so it can still act as a multi-meter.
FRS radio transmission. I hope to use this in my efforts to map out antenna patterns in the future. This is a good one night project if you have all of the parts laying around.
