K3 from 100W to QRP

[Benny Aumala]

Joe,
if you follow QRO- and QRP-traffic and change 10 times back and forth,
you sure wish to have something to toggle easily between.
Multiturn is fine for adjusting. 2 preset power levels would be enough
for me.
I think about PF1.
But I can live with this multiturn potentiometer. The rig is superb.

Yes, I'm not complaining and Wayne has said there will be a low power tune
option coming.

Wayne/Eric, perhaps it would be a good idea to maintain a public list of all
the enhancement requests, so people know whats been asked for?
This could be done at Zerobeat, but it would take a while to compile the
list.


Anyway, a number of posibilities for Elecraft to consider at some future
date:
1) A Main Menu item to set power control coarseness
2) A CONFIG menu item to set coarseness
3) A MAIN MENU item to switch 'MON' from monitor to an alternative 'rate' of
power control and then a hold of MON would switch from fine to course.
4) Then to satisfy those who want course more often than fine, a CONFIG item
to toggle PWR and MON-PWR so one is course and one is fine and you can
choose which one is 'normal' power.

I's been suggested to me by someone not on this reflector (shame), that the
power control should perhaps be logarithmic - running in dB.
That sounds like a good idea.

An old miser kept a tame jackdaw, that used to steal pieces of money, and
hide them in a hole, which a cat observing, asked, "Why he would hoard up
those round shining things that he could make no use of?" "Why," said the
jackdaw, "my master has a whole chestfull, and makes no more use of them
that I do." -Jonathan Swift, satirist (1667-1745)

Or the faster you spin the knob the larger the stepping increment.

I'd make it go in 0.1W increments to 1W, 1W increments to 10W, then 5W incremments to 100W. That's about 40 steps. I don't know how many turns of the control that would need.
