[Elecraft] KPA100

[Ron D'Eau Claire]

You can QRP two ways:

1) Turn the power down (the obvious). The POWER control runs from zero to
100+ watts. The KPA100 is switched out of the transmit path below 10 watts. 

2) You can switch the KPA100 amplifier off using the MENU command. Now the
rig behaves exactly like it did without the KPA100 except that you have the
advantage of the SWR bridge and SWR display on the K2 and, of course, the
SO239 connector on the KPA100 remains the normal antenna connector. 

With the KPA100 off the total K2 current drain is 8 to 10% higher due to the
circuits in the KPA100 that run even in standby. That's normally of no
concern unless you're running from a limited battery supply. People
operating portable in the field may simply swap the covers, removing the
KPA100 and putting the "QRP" top back on with its built in antenna tuner and
battery supply.

If I add the KPA100 to my K2 and decide I want to operate qrp, is there a
way to bypass the kpa100, or do you just turn down the power knob? It will
be a long time before I fully understand the K2. Thanks Scott N5SM K2 #5846
