Well, I certainly have opinions of all sorts. Here is mine WRT matching power supplies: a bit on the silly side. I replaced my brutish linear with sleek switchers half the size of my K3 with no discernible ill effects. I have two 7" x 7.5" x 2" 13.8 VDC x 25 amp units from Radio Shack and one only slightly larger from Pyramid. They are fan-cooled but very quiet, and only the Pyramid has the leads coming out the front. Since the only control in evidence is an on/off switch, these little guys can live their lives in the background, leaving operating space for other items such as a log & a set of paddles, or even a lap-top. Over and over again we hear bad vibes about switchers, but my power supplies and my computer live within 2' of my K3 and my ICOM 910H with no deleterious effects in either direction. They contribute nothing WRT noise or birdies.Once again, it is "physician, heal thyself" for those who have problems with them. The really neat thing is that the switchers are portable. They're not much good without an AC outlet, (e.g. mobile in the underbrush) but they are a very easy carry when the mains are available, and form the nucleus of a nice hotel-room portable: K3 + small switcher + "trailing antenna" (apologies to old-time pilots out there). My K3 with its parasitic SignaLink USB is happy as a non-Gulf oyster on its Pyramid switcher.
