About LPU

"LPU" is the project-name for a simple HPSDR power supply. Although power supplies are widely available, the LPU will provide a convenient low-noise solution until the more complex Demeter power supply is completed. The LPU (as well as Demeter) are specifically designed for the HPSDR project. With the approaching release of Mercury, this is the last hardware part of a basic functional HPSDR transceiver.

The LPU will not take the place of Demeter; it is intended as an interim solution to power HPSDR boards until Demeter is completed.

The project leader for LPU is Scotty, WA2DFI.
