Re: Accurate way to measure RF power??

 

I like the BAV21, which is a high voltage, small signal diode.?

I built a wattmeter from an article by W8TEE and AC8GY in QST of November, 2018. It's an Arduino based project.? I didn't build their dummy load though, preferring to use one of my own.

I believe my wattmeter is reasonably accurate from 1 W to 150 W.

W7zoi showed how to build high power attenuators in that article.?
Do you really care if whatever makes 94 or 106 watts before you go to that trouble? Fun enough to evaluate 5 or so watts.?
