[Elecraft] High Current only on 20 Meters

[Don Wilhelm]

Lee,

What is the voltage out of your power supply during transmit?  View it 
with the K3 ALT VFO B display.  If it is below 12 volts, check your 
power supply connections.  If you are powering the K3 through a 
RigRunner or other DC distribution system, eliminate it for the K3 and 
connect directly to the power supply terminals.

The K3 will try to keep the power constant, so if the voltage is low, 
the current must go up.
