[Elecraft] K3 2 meter capability: internal K144XV or XV144 transverter?

[AD6XY]

It is really up to you but a 100W VHF amplifier should not need more than 10W
of drive, typically much less. A 300W will amplifier perhaps need more
drive. Of course the output will be cleaner if under run, so a 25W amplifier
running 10W ought to be cleaner than when running 25W.

You only really need 25W of drive if you are using a large triode and hoping
for 1500W, indeed perhaps more like 50W would be appropriate. For a 300w
solid state PA like the reccomended by me Tokyo Hi Power HL-350Vdx it makes
no difference. It has 10W, 25W and 50W input settings.
