[Elecraft] Re: K2 power with and without PA

[wayne burdick]

Installing the KPA100 increases the K2's receive-mode current drain by 
100-200 mA. So if minimizing current drain for battery operation is a 
consideration, you might want to remove the KPA100 temporarily. 
Removing the six screws and unplugging the unit takes about one minute.

As an alternative, many of our customers have installed the KPA100 in 
our full-height KAT100-2 ATU rather than in the K2 itself. This makes 
it easy to grab the K2 and leave the QRO hardware behind -- just unplug 
the RF and control cables.

As mentInstalling the KPA100 increases K2 receive-mode current drain by 
approximately 100-200 mA. In transmit mode, additional current is 
drawn, but this will not be included in the voltage/current display.
