I always wanted to build a RF Wattmeter with the AD8307 and OZ2CPU design. I was looking for PIC MCUs and found that PIC16F876 is going to NRND, so after this I found it was the best time to start this project. It's a AD8307 RF Wattmeter from OZ2CPU in a PCB that can be placed on a Hammond 1590B box.

ATTENTION KNOW BUGS:

For V1.0 boards:

• The PCB project suffer from a pin swap on MC78L05. Pin 1 and Pin 3 are swapped, you MUST correct it on your building or your PIC will die from overvoltage.
• I put a place for a 16x2 LCD but the correct one is a 20x4!
• It won't fit a 1590B because of the 20x4 LCD :(
