Hello, As i use principally JT65A (snice ~ 2years), i've remarked transmit output power variations depending where the audio is located in the waterfall, as i'm not speaking English, it's difficult to explain correctly; if i'm ~ in the middle of the waterfall (~ 1200Hz) i get over 3dB in output power variations; for an expected 50W output power, between some tones of the JT65A modulation, the output level can vary from 20W to 60W; if i'm working away from the "middle", variations are lower and acceptable but most of time, "central" frequencies are used... I've always worked with this "problem" as i expect some AGC effect by the receiving side... I would appreciate to have an explanation of this effect.
Many TNX for an answer. 73 QRO de Rudolf, HB9ARI PS With the same sound card and software, using my "old" FT857 (non D) TX/RX, the output power variation is well under 1dB until the audio band edges. ______________________________________________________________ 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
