[Elecraft] K2 100 Watt Pa Problem

[wb2srf at juno.com]

>From the description of your problem it could be your power supply. 
Check the power supply voltage with a analog or digital voltmeter, under
load it should not drop below 12V. The K2/ KPA100 requires a good high
current power supply. I use an Alinco DM-330MV set to 13.8V. This power
supply is rated for an output current of up to 32 Amperes.
