Would it be possible to write a macro to suit this?

Hmmm. I think the software feature you want is already in the K3.
Use, the CW mode, adjust the keyer to 30 WPM or so, and you have a 50%
duty cycle pulser - just hold down the dot paddle. If you want a
lower duty cycle,
Interesting that a new article on eHam suggests programming one of the CW
memories with a series of dits. You would have to be in CW mode for it to
work.

Your are absolutely right Jim and that is the way I tune my amp using the
Vibroplex paddle sending dots at 40 wpm and using the PEP wattmeter of my
PalStar antenna tuner to get maximun ouput Even when I am on SSB I do that
as well
I suppose it would save you the price of a bug or a set of paddles (or at a
minimum, the cost of a 555 chip and a few discrete components), but I'm also
sure the new owner of Vibroplex (Scott, W4PA) would appreciate the business.
Even if you're not a CW op, you need a bug, just to call the

This would be an option to have the TUNE hold function send
interrupted 40 wpm dots instead of a solid tone? I'd use it all the
time. Personally I don't normally need TUNE except to tune an amp
behind the K3
There is a company out there that makes a little devise for tuning tube HF
amplifier finals. It uses a single pulsed tone at a 30% on 70% off duty-cycle,
one can see the advantage of this device in tuning up those expensive tubes.
Could such an arrangement be incorporated in the software of

Hi Richard
Foxtango used to make a kit. Theres one thats being sold on the net called
3898 Pecker. Expensive price for what it is.
Anyway I made up some PCB's for these for some friends a while back. I might
still have 1 or 2 left in the junkbox. This PCB is for the original FoxTango
