[Elecraft] Question about K2 power meter

[David Douglass]

Jeff,

This variation in power out during tuning seems quite normal to me, and my
K2(100) does exactly the same..

It never used to bother me but I recently bought a Emtron DX-1 amp, and it
makes tuning the amp pretty tricky.. I only need about 30w to drive the amp
to full output, but during tune up the power out from K2/100 will creep up
and trip out the Overdrive on the amp. It would be nice to just dial up the
required power from the K2 you wanted and get it, but I suppose I'll just
have to live with this little quirk. I still wouldn't trade K2 for another
radio!!

David, VK2NU

Hi Don,

Thanks for the replies.

To answer your questions, the problem occurs into a dummy load.

I set the base K2 (without KPA100 connected) to 5.0W, and then TUNE,
and it starts at 5.0W and heads upwards to 5.7-6.0W (read from the
display, as well as the S-meter). After about 10 seconds in TUNE, it's
up to 5.7 or 6W and the next LED on the S-meter is starting to flicker
some.

Moving the power knob will allow me to bring it back to 5.0W, but the
next TUNE will see the power climb back up again.

I'm not sure if I should still be looking on the RF board at this
point, or start focusing on the control board...?

Thanks, 73,

Jeff
