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. Ron AC7AC -----Original Message----- 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.
