[Elecraft] Which PS for K2/100, linear or switcher?

2006-02-27 Thread Darwin, Keith
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. My Alinco DM-330MV

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
