Threads like this one about power supplies must make both the transceiver manufacturers and power supply manufacturers gnash their teeth and give up in despair! The market already contains a number of very small, interference-free supplies that fit this idea: Pyramid, for example makes a 30 A. 13.8 V. switcher that measures 8"X8.5"X2.5" that sells for a reasonable price, and Tandy also sells one, slightly smaller, that delivers 20 A. I have three of these, quite a bit smaller than a K2, that work beautifully. They sit about 4" from my K3 and my ICOM 910H, and produce no discernible interference whatever.
There may be a need for a much higher capacity switcher -- I have not been able to find one that would replace my 2-ton-Tessie Astron 70 -- but the low end is very well covered. It seems quite counter-productive to shunt high-quality transceiver engineers into the power supply business...the K3 is nearly unique, ditto for the KPA-500, but it looks to me that the power supply issue is pretty well covered. Maybe Elecraft should just sell a "meatball" decal emblem for use on third-party power supplies?
