If I want to halt an in-progress transmission, if I wait for a few seconds after the start of the Tx period and then hit the 'Halt Tx' button, the audio is generated correctly during the next Tx period whereas if I halt a transmission immediately after the start of a Tx period then the audio is absent during the following Tx period. I haven't tested this rigorously or exhaustively, but it's certainly the impression I've formed over many, many hours of using the JT/FT modes. I don't recall ever having observed the absence of audio during a Tx period if I'd let the previous Tx cycle run through to normal completion. As Al K6AVP has pointed out, it's definitely not a band-edge issue - like Al I've always used the 'Fake It' option for split operation so my Tx audio is always within the 'sweet' range of 1500 to 2000Hz. -- 73, Martin G0HDB --- This email has been checked for viruses by Avast antivirus software. https://www.avast.com/antivirus _______________________________________________ wsjt-devel mailing list wsjt-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/wsjt-devel
