Today I noticed that the output power on 15 meters does not reach 100w. The max, according to the front panel meter reading, is 93w. So, I ran the transmitter gain calibration and it did not help. I decreased the power to 90w and it reached 90w, so I gradually increased the power and it is fine up to 93w. When set to 94w and above the max output is 93w. I checked all other bands and with the exception of 17 meters they are fine. The same low power output occurs on 17 meters.
I then tried my other K3 going through the exact same testing order and received the exact same results. They are both the exact same configuration. Specifics: - testing into both a dummy load (2 different ones) and 3 different 15 meter antennas - both K3 rigs are running latest firmware (5.38 / 2.86 / 2.86 / 1.25) - The power supply voltage at the rigs is 13.8 and drops to around 13.0 when in transmit - Reran the Transmitter Gain Calib - no help. NOTE: The new KSYN3As were just installed in both rigs including the second RX (2 weeks ago) Suggestions? 73, Bruce-N1LN ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [email protected]
