My plans to get a K2/100 continue full speed ahead. Omni V.9 is up on
e-bay and I'm in the process of getting my ducks in a row before I pull
the trigger and commit to a particular rig (new or used is TBD).
But what about the PS? Which one should I get? Should I go with the
less costly Astron

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.

I'm using a Rigrunner power strip and I have a 25 amp fuse in the K2's slot.
If you are really drawing 20 amps (or more), that suggests some issues with
your output bandpass filters.

Hi Vic,
Well I also opted for a 35A 'linear' supply for my K2/100 because I did not
want the
I have several Astron power supplies. Always have used them. What are they ?
Are they switchers are what. I will admit I have never known. I do know they
are quiet.

The noise from a switching power supply comes in via the antenna, so if
the antenna is located suitably distant, the P.S. can be located next to
the rig and you won't hear the noise.
All switchers generate noise to some degree. For those that say their
switcher dosen't, they should locate

One other thing to keep in mind is that a slightly reactive load -- even
with a reasonable SWR -- may change the current draw significantly. I
think this was my issue, actually. Some band on which the antenna's SWR
was about 1.4:1 nevertheless drew much more current than the dummy
