Here are some measurements I made a couple of weeks ago with my FT-817 and KPA500:
Band: FT-817 Out = KPA500 Out 160 Meters: 6.0 Watts = 70 Watts. 80 Meters: 5.8 Watts = 75 Watts. 40 Meters: 5.3 Watts = 75 Watts. 30 Meters: 5.1 Watts = 75 Watts. 20 Meters: 5.1 Watts = 75 Watts. 17 Meters: 5.0 Watts = 80 Watts. 15 Meters: 5.0 Watts = 80 Watts. 12 Meters: 4.9 Watts = 90 Watts. 10 Meters: 4.9 Watts = 100 Watts. 6 Meters: 4.2 Watts = 125 Watts. The power output from my FT-817 was measured with an Oak Hills Research WM-2 QRP Wattmeter inserted between the FT-817 and the KPA500. The power output from the KPA500 into a MFJ-264 dummy load was measured with the KPA500's internal wattmeter and read from the digital readout on the front panel of the KPA500. All measurements were made with the FT-817 key down in CW mode on a frequency in the CW segment of each band. I use my KPA500 with my K3, not my FT-817, but an amplifier discussion on the FT-817 group led me to make this test to satisfy my own curiosity. 73, Bill - NA5DX ______________________________________________________________ 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
