[Elecraft] K2 KPA100 transmit test: fail

[Ron D'Eau Claire]

I've heard many extremely powerful signals reduce the audio output from even
the best receivers in commercial communications facilities. It's a very
common phenomenon. 

Glad all is okay Brian. Those results are well within the typical margin of
error for RF power measurements. 

Have fun!

Hi all,

Here's the results of my power measurements:

Requested/Measured Power

5 W   -->  5.81 W
10 W --> 11.06 W
11 W --> 11.93 W
20 W --> 18.22 W
30 W --> 30.25 W

Looks pretty good to me.

The take away lesson is not to rely on a separate receiver to judge signal
strength.

It's still a mystery to me why there is such a drop off in heard signal
strength going from 10 to 11 W, but the wattmeter doesn't lie.

Thanks to all that helped out and putting my mind at ease!  Now on to
testing on the rest of the bands.....
