A 35 Amp supply is *way* over-kill for a K2/100. A 20 amp supply provides
all the power you need at 100 watts with several amps to spare to run other
things. My K2/100 draws, typically 16 amps "wide open" on the bands
requiring the highest current.
Well...actually some K2/100's draw more power. Mine does take up to 20
amps on some bands. The 35-amp Astron runs all kinds of things in my
shack and is also usable with another transceiver that I have that does
take more current.
The advantage of the linear supply is: no electrical noise generation.
Disadvantage: must be at least 2 feet from K2 due to magnetic field.
The advantages of the switchers are: physically lighter and smaller,
smaller or no magnetic field. Disadvantage: possible electrical noise
generation.
Many people will tell you that such-and-such a switcher is totally
quiet. This seems to vary by particular unit. It also depends on your
antenna and feedline, and the particular frequency. I personally am
sticking with the linear supply.
