KX2 Low Power

Rick Dwight
The first thing I would check is what voltage (under TX load) is actually reaching the KX2.
Check this in the menu and also right near where the power enters the KX2.  Full power is only possible
With a good “stiff” power supply.  If you use the internal battery pack, the power will drop off, perhaps
around what you get, after a little use, but then you can operate for some hours at QRP power levels.
If you run the KX2 with a good AC power supply which puts out hopefully at least 13 volts, you should
get the full specified power.  Even something like a 12 volt gel cell, will soon drop down below 12 volts and
may or may not support full power.  If you have small wires between an external supply and an in line fuse
this could be a slight possibility.  Check the above things out first since it is an easy step.  If you are
measuring the power output with an inline SWR/wattmeter into an antenna without perfect 50 ohm
SWR of 1:1 the power reading from it could easily be off by 50 %.  Good Luck,
