High-Z Active RF/AF Probe with AGC. Making something good even better.

Only $5 for 10 PCBs and every new member get $5 bonus. + Express 24 hour / 48 hour service on https://www.pcbway.com/
After my first attempt at building an active high-impedance RF/AF probe, many of you asked about adding an AGC function, so I went looking for a solution. I think I found it.
The result was quite surprising. Not only is it extremely sensitive, but the use of a commercially available preamp module with AGC makes this a really simple solution to build. The PCB files that I have made available through the PCBWay Share page also makes it easy for anyone to order boards and build their own.
CORRECTION: I mention that the preamp unit is a MAX4066. Obviously this is incorrect. It's a MAX9814 unit.
SCHEMATIC: her's the link to the schematic, in the event that it is not clear from the video: https://drive.google.com/file/d/1YHeX...
The Gerber files are available on the PCBWay website in the share section, so feel free to order your own boards and try out this handy gadget. Here is the link:
