[Elecraft] K3 Switching Power Supply

[Phil & Debbie Salas]

I've been using a SEC-1235 with my K3 for over a year now.  Works great with 
no switching noise.  I did modifiy the power supply by adding a PowerPole 
output connector pair on the rear.  I also made a simple mod to the SEC-1235 
fan circuitry so the fan runs slowly all the time, but can still go to high 
speed if it is ever necessary (info at www.ad5x.com in the "Equipment 
Modification" section).
