Hi Can be done with a couple of switchers. I'd do the switcher => LDO trick to clean things up. Bert has a setup running that way.
I would not try to run one directly off of a battery. Either you would have a pretty big battery, or it would not last long.

Something like you do with pico amp meters, or I do with the Fluke 845AB null meter ? -pete On Sun, Feb 13, 2011 at 11:29 PM, Flemming Larsen <[email protected]> wrote: > I have a Power-One switching power supply that puts out +/- 15 Volts in addition to +5 Volts.

They appear to be ideal for powering the Thunderbird from almost any DC power source, including a 12 Volt battery. > > -- Flemming Larsen, OZ6OI/KB6ADS > > [email protected] > > > >> > > > > _______________________________________________ > time-nuts mailing list -- [email protected] > To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts > and follow the instructions there. > _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there. _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
