[Elecraft] Which of these would make the best power supply for the K3(S)?

[Charlie T, K3ICH]

We're quite lucky here in nawthrun Vuhginya to be
on an electric coop where our juice runs between
11¢ to 12¢ per kw-hr.

However, I personally find it distasteful to leave
a linear power supply "idling" 24/7 not running
anything.

In reality, I'm just plain too cheap to waste the
power to keep a big linear supply on all the time.

My K3s and VHF tri-bander are powered by a 24C
battery, charged through a 45 watt solar panel
system.

I do turn on the "aux" 4 Amp charger when I am
actually transmitting to keep the DC up a bit.

You might not do that if you lived in W6, where,
thanks to Enron, the cost of power is MUCH higher
than in most of the US. In Chicago, my worst case
differential cost of power was about $0.13/kWh;
here in CA, it's in the range of $0.36/kWh. In
Chicago, an Astron ran 24/7. In CA, I use the
quietest, most efficient switcher I can find,
supplementing it with solar panels during the
summer months.
