4300-400, Modification Kit
Peak Power Reading
The Bird Model 4300-400 modification kit is designed for easy installation in any Bird Model 43 Wattmeter to convert the instrument to read peak power in AM, SSB, and certain limited pulse applications. Installation of the kit does not affect the model 43’s ability to read CW power (no amplitude modulation).
No special elements are required for peak power measurements. However, element power ratings must match the peak power to be read. For example, if power output peaks of 1000 W are to be measured, a 1000 W element should be used in the meter.
