[Elecraft] K3-100 Low Power Output

[Don Wilhelm]

Greg,

What is the voltage from your power supply during an attempt to achieve 
100 watts output.  It should be 12 volts or greater.  Check with the the 
voltmeter at the K3 end rather than the power supply. The K3 will 
display the voltage in the VFO B area.

If the voltage is the problem, check your power supply and its cabling.  
Make certain all connections are tight and low resistance.
