Amerigo,
Are you expecting that if you get the SWR lower your finals will run cooler?
Because the reflected power into them will be less?

If it were solid state, I can see wanting to get below 2:1 a bit..
Gives
you more usable bandwidth. But for the hybrid kenwoods with 6146's,
it really doesn't matter. Improving his match from 2:1 will not really
make any difference at all. With those radios, as long as the load
can be matched with the "LOAD" control within it's normal setting
range, it's good nuff. I doubt a 2:1 load is off enough to hurt a pair
of those tubes as far as any extra heat. The radios have a fan.
So.. He can improve it, if he doesn't have anything else to do,
but I would not expect it to make any real difference, except
that the "LOAD" control will end up being in it's more normal
appx 1/3 to 1/2 setting rather than lower, or higher.
It will not effect his signal at all. Any difference would be
unnoticable.
