[aprssig] Prius Power for Field Day

Is there much/any electrical (RF NOISE) generated by your mobile power
supply? I have a Ford Escape Hybrid (2006) that below 30 MHz wipes all but
S9+ signals out. One of these days I'll have to replace it, and am just
wondering if you have similar issues

Now that I see that the 12 volt power supply works on 240 VDC
input, I can bring along a few of these to field day, and power
every tent's 12 VDC systems from the 220 VDC battery in my
Prius. And if the battery runs down to 40% depth of discharge,
then the Prius engine automatically starts re-charging it with
its 10 kW generator.
A whole lot quieter than those 120 dB generators that drone on
Oh, and if the load is under 200 watts continuous and the sun is
shining, then my Prius internal combustion engine will not even
crank up. Till the sun goes down... See:
Now I am working on 240 VDC connectors so that there is no
possible way for anyone to plug in the wrong thing to the DC...
Oh, and lots of fuses everywhere...
