[hpsdr] Munin Power

[rodwall1234 at gmail.com]

Hi Gordon,


I emailed Kjell and this is what he said:


Munin needs 13,8V +20% -5% for the best performance. At least 20A continuous current is needed, 25-30A peak.

I am a very happy owner of a Munin kit -  a hearty thanks to Don and Kjell.

 

Looking at the circuit board and the schematic, I see power requirements of +/- 13.8V.  I had hoped to supply power from a clean PC power supply (12V).  

 

Two questions:

                1. Hopefully,  I don't need +13.8V and -13.8V for a total of 27.6V.  Correct?

                2. If I only supply 12V will a get the same performance, but at reduced power?
