Jean-Francois, Ther is no need to turn off the KPA100 in the menu - just remove the power from the KPA100 and power the base K2 at the coaxial power connector - the display will come up with 'No PA PS' when you power the base K2 and you will have the full 0.1 to 15.2 watt power range available.
You can certainly take the output from the low power BNC, but I would not recommend it - you would be feeding the KPA100 input (still connected to the AUX RF connector) in parallel with your antenna load - that is just 'not right', so it would be best to take the output from the KPA100 SO-239 connector - the KPA100 will be in 'bypass' with only its Low Pass Filters and the wattmeter in the circuit. Note well that the wattmeter must be in the path to the antenna in order for the K2 to correctly control the power output - so by using the BNC connector, the wattmeter would not see the true output power and the microprocessor would be trying to set the power based on erroneous information being sent to it from the wattmeter residual data. Bottom line - use the SO-239 antenna output unless you completely remove the KPA100. 73, Don W3FPR > -----Original Message----- > > I would like to know if I use my K2 with the KPA-100 for outdoor > operation, and if I turn off the KPA-100 from the menu and also if I > powered my K2 from the samll DC connector instrad of the Powerpole > connector ...
