There are IMD graphs of KX3 at different power and voltage levels in FILES on
KX3 group at yahoo. IMD3 levels sharply increase with higher power and lower
voltage.
The IMD is are important only IMHO if KX3 is used at very high power level
on a crowded band. It is irrelevant for QRP operation.
Also, when the KX3 is used to drive a KXPA100, the rig is typically operating
at well below maximum power, reducing IMD levels.

hi all,
we made 2 tone measurements of my KX3 and compared it with my FT-817.
There was one unexpected result with the KX3, and I would like to ask the group
if this is
already known or looks like a problem with my KX3.
The IM3 peak is lower than the IM5 peak and it is asymmetric.

Hi Werner,

This is not unusual with MOSFET power amplifiers. We've seen such effects with
10- to 100-watt amplifiers made by various manufacturers.
