Jeff & all.
Sorry I wasn't more specific on my request.
I want to create a lightweight DXpedition amplifier
package. I will NOT be using the amp mobile, but
running off of standard 110/220v power.
It's easy to find inexpensive RF decks of 1000w output
using 12v transistors, but they draw a lot of juice.
Since this is going to be a DXpedition package, I am
looking for a single PS that is 12v and 100 to 170
amps. While ganging together multiple 5v versions
would work, the weight is too much for this project.
I already have a FB amp I take on DXpeditions (Acom
1000) and that weighs 48 lbs. The goal of my current
project is to put together a KW amp that weighs ~25
lbs inclusive of both the RF deck and power supply.
Since the RF decks usually weigh 8-10 lbs, the PS
needs to be in the 15-18 lb class.
Many thanks, Kenny K2KW
