[Elecraft] KX1 Power Output

[Don Wilhelm]

Tom,

Yes, your values look reasonable.  The KX1 will always indicate that the 
voltage is about 0.4 volts lower than read at your supply.  There is a 
series diode to prevent damage from reverse polarity, so the inside of 
the KX1 sees a voltage that is one diode drop less than your supply.
