If anyone needs information on the older KLM/Mirage amplifiers, I have some of the original documentation when I was at KLM/Mirage in the '70/'80 time period. Would be glad to share.

CW is 100% modulation of a carrier by a rectangular wave, so the harmonics associated with rise and fall times create at least as much distortion as SSB. That distortion shows up in the form of clicky sidebands. It's quite easy to see these sidebands on a P3. Here's some work I did a year or two ago measuring some rigs that were available to me. http://k9yc.com/P3_Spectrum_Measurements.pdf The second file contains much of the same data, but focuses on improvements made by firmware upgrades to the FTDX5000 a year or two ago. http://k9yc.com/FTDX5000_Report.pdf 73, Jim K9YC ______________________________________________________________ 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 farrerfo...@yahoo.com ______________________________________________________________ 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
