Regarding the procedure in the KXPA100 Owner's manual, does the output indicate 75 watts when you set the power for 75 watts as the procedure states? Was that done into a good 50-ohm dummy load?
How does it behave on other bands? Remember the calibration must be done on each band and you will need to reset the POWER control for CAL 75 on 50 MHz. 73, Ron AC7AC -----Original Message----- From: Elecraft [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of Tom Field Sent: Saturday, April 16, 2016 5:30 PM To: elecraft@mailman.qth.net Subject: [Elecraft] KXPA Power Output I'm having difficulty getting more than about 70 to 80 watts out of the KXPA 100. I have it connected to a KX3 with the Elecraft cable and have gone through the calibration procedure as outlined in the owners manual and in Fred Cady's excellent book. For Example if I go through the calibration procedure on 40 meters, It appears to show a drive level of 5 watts to achieve 75 watt output. If I transmit into a dummy load, with the power setting at 100 watts, I have a drive power of about 2.6 watts and an output power of about 70 watts as shown in the KXPA Utility. Am I missing something?
