[Elecraft] K3/100 power supply

[Gary K9GS]

So...If I were to tweak the power supply voltage should I use the K3 
internal voltmeter or an external one?  If an external one, I assume 
connected at the DC input to the K3 to compensate for any voltage drop.

Also, should I set the voltage under load/while transmitting?  I guess 
that would depend on how good the voltage regulation is?
