I obtained a brand-new calibrated 25H element for my Bird43 power meter, today. I checked power out on my K3/10 set to 12.0w. 80m = 11w 40m = 11w 20m = 11.5w 15m = 11.5w 10m = 11.5w all measurements into a Bird 25w coaxial termination
I assume running the Tx gain calib. at 5w will result in adjusting the upper end of power output to 12.0w. Or is the power that I am seeing the max available? I had previously measured output at 15w with my 100H element but this is apparently in error. The 100H element is old so probably out of calibration and accuracy at 15% full scale is not that good, anyway. I tested at 5.0w at 28 MHz comparing the reading using the 25H element with a 5A element and got exactly the same reading. 73, Ed - KL7UW, WD2XSH/45 ====================================== BP40IQ 500 KHz - 10-GHz www.kl7uw.com EME: 50-1.1kw?, 144-1.4kw, 432-QRT, 1296-?, 3400-?
