FW: Power Supply Ferrite Beads.

[Dan Barker]

I just gave up on the whole thing, bought a car battery and a $20 trickle
charger. Two (both sides) 30A fuse holders and it even works after the power
goes out. A bit heavy, but a great addition to the bench! Pretty clean
power<g>!

I would like some advice on the correct Ferrite beads

A Word of caution Charging Car Batteries give off  HYDROGEN GAS don't
charge them indoors in a closed room

My solution is similar. I use a sealed 12 AH gelcell 'jumpstart' battery with a
built in charger (paid $50 at AutoZone, but seen for as low as $40).

Here's a link to the Mity Mite:
http://www.batterychargers.com/details.cfm?prodid=PS%2D120A&catid=13

I leave it plugged into the outlet all of the time (float charge ... takes a
few days to top it off if I've drained it significantly). Sometimes I'll unplug
it to see if I'm getting much RFI from the charger - but it is usually very
little.

I went with a 12 AH because it should be more than enough for me to use for
Field Day each year with my K2/QRP.

p.s. No Hydrogen problem with this set up (that I am aware of).

p.p.s. I keep this in the bedroom underneath the student desk by the window I
operate from. If it was a real car battery or deep cycle battery - I'd probably
keep it outside, and run the power through the window/wall to avoid Hydrogen
because it can be a serious danger - even with a trickle charger.
