Hi all, i purchased a 12vdc to 240vac inverter for using my laptop. it's a
300 watt model fromm Jaycar.
I asked the person running the shop if i could run my 100w IC725 from it. NO
WAY was the reply.

I was thinking of running the DSE D-3800 power supply from it when out on
contests and running the laptop and ssb hf rig from it.

Gary-

This is one of those things you can try and see if it will work!

Instead of estimating the power your equipment needs, you need to find a
way measure it. I measured power consumed of an HF rig putting out 100
Watts CW, and found the actual AC consumption was about 350 Watts.

JB-

As far as needing 13.8 Volts instead of 12.3, there is a product on the
market designed just for that problem. One version was published in QST
several years ago, and may be currently marketed by the original author.
Another variation is the MFJ-4416.
