Hello all,

Looking for a power supply for HPSDR?

I have progressed to a real design of the Linear Power Unit (LPU), 
and it is up on a wiki page here:

http://hpsdr.org/wiki/index.php?title=LPU


Please take a look and comment. Keep in mind the goal of LPU:

small, simple, inexpensive

no redundant "safety" features (e.g. no crowbar, over-current, etc)

designed to use regulated station power supply for input

efficiency is not a concern

temporary use (it does not replace Demeter, but can be used until 
Demeter is complete)

+12V, +5V and -12V only (with +3.3V as a user-buildable option to reduce cost)


If this looks OK, a kit can possibly be produced very quickly due to 
the simplicity of the design.

73,
