Are you ignoring the crest factor of the two tone test signal?
To get 100 watts average RF power from a "two tone" signal, the
instantaneous peak power has to be nearly 200 wat
Hi Jim,
I use K3 internal 2 tones test function + SDR-IQ+ SpectraVue3. If need
I can use HP RF spectrum monitor to test it.

I have measured myself however didn´t come up
with as poor and/or as good numbers.
What could be interesting is with what and how
did you measure.

Hello All,
I checked my K3's TX IMD today(K3 SN:1302), from 5W to 110W. Very good
TX IMD when I set the output power to 35w( 50db), but very poor when I set
it to 100w or 110w(20~18db).
Any one can help?
I have about 10 photos for this test, if interest I can send via email
offline.
