There you go Don,what could be easier and cheaper than an old discontinued mouse wired to that 1/4" stereo plug,and as I said,I configured my K3 to send CW when I am in SSB,so push the mouse and tune the amp,that's a killer,I bet it will cost less than five bucks.
Thanls for that idea.

Hector,

IMHO - Finally a voice of sensibility in this discussion.
I will offer yet another suggestion for those who do not want to find a box and a switch - find an old computer mouse - those that have real switches on the buttons (the mouse ball does not have to work).  Wire either 1 or both switches to the 1/4 inch plug.  Now you have a "paddle" that can send either dots or dashes.  Set the speed to about 40 wpm, press the dot side and tune the amp  If you want to use a greater duty cycle to refind the amp's tuning, just press the dash side.

If you dislike switching to CW mode for tuning, just go to the menu and add CW in SSB.

I have always thought the "Pulser" was just another gadget to clutter up the hamshack.  We have tuned amplifiers for years without them, and things worked out just fine.  But I also know there are strong advocates of the Pulser that will not be swayed - something about a 30% duty cycle, and a string of dots produces a 50% cycle without changes in the weighting..

73,
Don W3FPR
