[Elecraft] K2 Pwr Out Problems

[David Douglass]

Hi All,

My K2 seems to have developed a power output problem.

Set-up is a QRP K2, with SSB, internal ATU and KIO2 options.

I get full power output on CW OK, but only get a Max of about 1w RF output on SSB.

If I remove the top lid, and therefore disconnect the internal ATU and KIO2, I then get full output on SSB and CW.

I've also tried just plugging in the ATU and leaving the KIO2 out of line, and this seems to give full output??

Could there be a problem on the KIO2 that is causing me to loose SSB output?? Leaving the KIO2 inline but turning it on and off in the menu does not effect things.

Any ideas..

Thanks
