Tom: The spectrum of a OOK (CW) signal at 3 wpm is different from the spectrum at 30 wpm, so what does the last phrase in your response mean? The signals will have energy content at (carrier rate +/- symbol rate), so the 30 wpm signal would qualify as "more bandwidth" in my book.

It could go back to the engineering people relying on the ARRL for technical standards, such as the poor waveforms shown in the Handbooks as "optimal", and the incorrect notion that CW changes occupied bandwidth with keying speed. <CLIP> 73 Tom _______________________________________________ Topband mailing list Topband@contesting.com http://lists.contesting.com/mailman/listinfo/topband |
