[Elecraft] TUNING PULSER

Bob,

What is your "pulser" doing to induce transmit?  How is it connected?

I am thinking it may be running into a conflict with the way the K3 
controls power.
After a band change or a change in the requested power, the power output 
starts out low and then ramps up to the requested level (better than 
power 'spiking' as some other transceivers are guilty of) - for CW, that 
should take 2 or 3 dot times, for voice modes how fast it comes up to 
the requested power depends on the syllabic nature of speech.

Is the 100 watts the output of the amp or the output of the K3?

The K3 has a "built-in" pulser of sorts - it is the internal keyer. just 
send a string of dots or dashes.  You may want to try using that instead.

73,

If I use the pulser now to adjust the amp the power will go up slowly to over 100 watts.. I have tried either plug on the back of the K3 but get the same results. What do I need to do to get this pulser to work right?   73s Bob W5RG
