[Waverley ARS] Power Supply for ICOM 718

[Adam Carmichael]

Hi Brad and List,

I've had several positive pieces of feedback about the D3800, and 
thankfully one has landed in my lap (although not literally because it's 
a beast of a thing and would really hurt!)

It even has a little red dot on the voltage meter for 13.8V, so I'm 
going to add a little red dot on the knob position for 13.8V (about the 
only "fault"/feature enhancement I can find with it without having had a 
reason to power it up yet).

Thanks all for the feedback!

Adam
