Hi all. I'm new to HF, new to the K3, and relatively new to ham radio so please go easy on me.
I only have my Technician so I've been listening a lot more than transmitting. I completed assembly of the radio about a year ago but left out the KPA3 until I was sure the radio was working correctly. (Did I mention this was an old kit I got from a SK auction a year ago?) I decided this past weekend to install the KPA3. Installation went perfectly, the radio passed its TX calibration and I started looking at more power. Now something odd seems to be happening. I've included the power calibration results below for complete information. K3 TX Gain Calibration data written on 2022-12-14 at 17:04:45 K3 Serial Number 00746 K3 MCU version 05.67 on COM9 at 38400 bit/s Elecraft K3 Utility Version 1.20.1.15 1900 kHz TXGain LP 36 3750 kHz TXGain LP 21 5336 kHz TXGain LP 28 7150 kHz TXGain LP 35 10125 kHz TXGain LP 30 14200 kHz TXGain LP 16 18110 kHz TXGain LP 19 21200 kHz TXGain LP 14 24930 kHz TXGain LP 13 29000 kHz TXGain LP 21 52000 kHz TXGain LP 19 1900 kHz TXGain HP 30 3750 kHz TXGain HP 36 5336 kHz TXGain HP 48 7150 kHz TXGain HP 56 10125 kHz TXGain HP 38 14200 kHz TXGain HP 18 18110 kHz TXGain HP 13 21200 kHz TXGain HP 10 24930 kHz TXGain HP 08 29000 kHz TXGain HP 18 52000 kHz TXGain HP 05 I'm running the output to a wattmeter from there to a 50W dummy load. When I key my paddle no matter how much power I set the amp to all I get as output on the onscreen RF meter is between 10 and 20W. The wattmeter seems to be registering correctly - as I increase power the output watts increase. If I transmit voice the onscreen RF meter will display up to 100W depending on the volume of my voice and the wattmeter appears to be reading correctly. Please note: I've made sure all my CW CONFIG settings are correct, and I'm sure I've got the radio set to the RF meter and not the ALC meter. Is there something I'm not understanding about the onscreen RF meter operation, or am I doing something wrong? Are there other tests I should be running? Thanks in advance for your patience! 73, Adrian KJ7SOY ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com
