Paul asked: I only have a QRP K2 but just would like to know what the min power a K2/100 will run at with the power know turned down ,
and what current does it draw at low power compared to the barefoot K2? ------------------------- When you turn the POWER below 10 watts the KPA100 is automatically switched out of the circuit, so it's just a "barefoot" QRP K2 at those power levels. If you're providing 13 VDC only to the high-current power connector on the KPA100, it'll draw between 200 and 400 mA even when it's not being used. If you want, you can power the K2 QRP circuits through the small power connector on the back of the K2 and power the KPA100 separately through its high-current Anderson connector. If you do that, when you remove power from the Anderson connector the current drain to the K2 is the same as any "QRP K2". You'll get a warning on the K2 display that you don't have amplifier power. To switch to QRO mode all you need to do is furnish 13 vdc to the Anderson connector on the KPA100. The system is designed to work FB that way with two power supplies.
