Re: [Elecraft] Tube Amplifiers
Would it be possible to write a macro to suit this? David G3UNA 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, simply tweak the weight option until you get what you want. If you have a monitor scope, or a general purpose scope that covers up to 30 MHz or so, you can use it to measure the on-off ratio. - Jim, KL7CC Richard Thorpe wrote: There is a company out there that makes a little devise for tuning tube HF amplifier finals.

Re: [Elecraft] Tube Amplifiers
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.

Re: [Elecraft] Tube Amplifiers
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 after enabled the feature that I can send morse with the mode switch on SSB,its like having a pulser inside the K3. No need to add any pulser in the firmware. Happy new year eve for all.

Re: [Elecraft] Tube Amplifiers
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 computer ... um, excuse me ... radio ... room a hamshack. Even if you only treat the bug like any other decorative accessory for photo ops and similar events ... you know, the unterminated cable end is snaked behind a radio and looks real ...

Re: [Elecraft] Tube Amplifiers
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. All my amps are tubes. I'm waiting for a ham band 1500 watt CCS transistor amp with a built-in auto-tuner before I ditch my 3CX1200s and 3-1000Z's. So I'd be using a pulser TUNE for a long time methinks. 73, Guy.

Hi Guy, Yup - that's it.
