[ARC5] [Milsurplus] Quieting A DC/DC Converter

[Brian]

Hello Ken,

Yes, I bought one of these, but wanted a lower output voltage. So, I 
analysed the circuit, and altered the Voltage sensing circuit by soldering a 
resistor over one already on the board to alter the sensing ratio. needed a 
bit of care with a needle-pointed soldering iron. Got the same efficiency 
and quiet enough to put inside a fairly sensitive Rx without spuries 
affecting  performance

Cheers, Brian, VK2GCE.

Hmmmm....looks very interesting. I see several other such models by 
different folks on
eBay.

Has anyone tried these yet?
