[Elecraft] [OT] Any good experience/recommendations with boost regulators with K3?

[Matthew Zilmer]

http://stores.tgelectronics.org/Detail.bok?no=10 works quite well.  I have two 50W Seimens PV modules feeding a charge controller, then to an Optima 75AH AGM.  The Optima is the shack supply.

Hey,

Sort of off topic, but I was wondering if anyone has any positive experience using boost regulators fed from a lead acid battery to drive their K3?  Specifically I'm wondering which models might be relatively free of emitted noise, are fairly efficient, and haven't messed up in a typical RF environment.

I use solar panels to keep a flooded lead acid battery array charged, then run my ham stuff from that - but the battery voltage does sag lower than I'd like under transmit, dropping down to about 12.0 VDC, so I'd like to get it closer to 13.8 under load by using a boost regulator.

Appreciate the bandwidth, and thanks in advance.

73, Bob, WB4SON
