Hi All re "Morse code speeds are conventionally defined in a very precise way. See, for example, http://www.kent-engineers.com/codespeed.htm .
The width of the main spectral lobe of a CW signal in Hz is roughly equal to the speed in WPM. Fairly strong secondary lobes occur at multiples of this number. Sending the CW ID at (say) 100 WPM, in order to squeze it into a 15 s Tx interval, would make the CW ID much wider than an FT8 signal. Most likely we will implement CW ID as a separate, dedicated transmission when the T/R sequence length is less than 30 s. NB: Since June 15, 1983 FCC does NOT require US amateurs to use a CWID with data modes. " That is a convention only As far as I know, but this might have changed since your last presidential election, but Kent Engineering is not a legislative body., and there are several different morse alphabets apart from latin characters. And as Joe also says there is no legal requirement in the US for data modes. For a convention to become law in a country it must be ratified by that countries legislative body, I seriously doubt if the majority of amateurs really understand their licence requirements. So in my opinion leave cw ident out. -- -- Best wishes /73 Richard Bown Email : rich...@g8jvm.com HTTP : http://www.g8jvm.com nil carborundum a illegitemis ################################################################################## Ham Call: G8JVM .
