#221: The Bird 43 Directional Wattmeter: Overview and how-to …

WebThe Bird 43 is an insertion-type RF wattmeter, designed to measure RF power and load match in 50 ohm coaxial transmission lines. It is intended for use with CW, AM, FM, and TV modulation, but not pulse modulation. The Bird 43, when used in 50 ohm applications, has a maximum VSWR of 1.05 for frequencies up to 1000 MHz. WebI used a small flat-blade alignment tool and adjusted the calibration pot in the Bird element so the meter read 80 watts. I found that the pot was noisy, so I rotated it back and forth several times to clean it, then I set it so the meter read 80 watts. I swapped elements several times to make sure nothing had changed.
