[Elecraft] KX2 Low Power
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 %.

[Elecraft] kx2 low power
Hello Barrie; ( I do not have product specific information on the KX2. ) A few comments/questions : - Did the person selling the KX2 make any representations as to the radio's condition ? - Do you know why the KX2 needed to have new finals ? Did the radio just suddenly cease transmitting or was there an associated event (static discharge, over-heating, etc) ? - After the finals were replaced were any measurements made to confirm that the KX2 was working properly on all the bands with the new parts installed ? - Are your measurements being made into a known good dummy load and with a good power supply ? - Have you browsed through the owner's manual so that you have a general idea what the various calibration procedures accomplish ? I'm not suggesting that you try to perform any of the procedures but rather are you familiar with them to the extent that you have an awareness of what they are ?
