I think that you're generally right, Don, but I FM with a keyed audio tone for CW qualify as MCW too?
A.M. MCW was specifically required for shipboard emergency "CW" communications. 73 Ron AC7AC -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Don Wilhelm Sent: Saturday, June 15, 2013 12:25 PM To: [email protected] Subject: Re: [Elecraft] Point me to the note for sending CW when in, SSB mode I have always thought of "MCW" as an AM signal - used so that receivers with only AM capability could copy them. OTOH, if a SSB signal with sufficient carrier and opposite sideband suppression is presented with an undistorted sine wave signal, it can be just as good as a CW signal. Unfortunately, all those conditions are not satisfied with CW in SSB where an open mic is also present. 73, Don W3FPR ______________________________________________________________ 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
