Hello Igor,
If you want to measure (with useful accuracy) the level of the IMD products
generated by your KX3 and HLA 300 Plus, all that you would need in addition
to your TS590 is a Two Tone (AF) Generator, an AF Spectrum Analyser and your
computer. If you Google Tcube you will find a program called Tcube, which
can be downloaded at no cost. This program will provide you with a Two Tone
Generator and an AF Spectrum Analyzer. The frequency range covered by the
generators and the Spectrum Analyser is 0 to 10 kHz. I have found this
program to be useful when running 3 or 4 tone tests, two of the tones from a
"hardware" generator.

I do not have equipment to accurately measure IMD of my combo of KX3 and
HLA 300 Plus. Having said that I drive HLA 300 with 5 w from KX3. It gives
me 200 + watt on all the bands. Listening to the radiated signal using
TS590 and different antenna reveals that the occupied bandwidth is within
the same boundaries which I have determined by transmitting 100 W from my
K3. Therefore I assumed that IMD of the above mentioned combo is no worth
then 30db.
