[Elecraft] 80 meters

Hi Bob, 


Rather than estimating the loss in your power cord, your K3 has the 
capability to accurately measure and display the DC power voltage 
internal to your transceiver. 


Tap DISPLAY and rotate the VFO B dial to show the K3 power 
supply voltage when you're transmitting.

I run my power supply at 14.0 volts as measured at the supply. This is 
done to accommodate the ~0.25 - ~0.35 volt drop in the DC line between 
the supply and the radio when in transmit.
