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.
