[Elecraft] K2 & KPA100 Problems.

[Bob Wehking]

I am now at the final checkout of my KPA100 & on page 47, there was an addendum to measure the voltage at the left side of R12. In the CW test mode, the voltage should be between 100-110 VDC while in the tune mode. I get zero.

I hooked up a LDG digital wattmeter & when I set the rig for 5 watts, I get 10 watts, radio readout shows 5.6 & swr 1.0:1. When is set the radio to 10 watts, the radio shows 10 watts but the watt meter show 20 watts. When I adjust the power for 20 watts, I show 26 on the radio & 39 watts on the watt meter. From that point on, no matter what power setting I set, my power out stays around 40 watts on the watt meter  on all bands & the radio shows 28watts. As I turn the power adjust to 70 & above, the output power drops to 30 watts on the wattmeter, still26 on the readout.

Any idesa why the power adjust on the basic K2 causes the K2 to put oot twice that of what is showing on the screen. Secondly why I don't have a reading at R12 & lastly why I can't get bore that 40 watts output?

Thanks
