[Elecraft] Tube Amplifiers

[Jim Wiley]

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.

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 the K3? what a handy feature to have for those of us that cannot live with just a 100 watts.  Happy New Year to all.
