Hello Rip, That is your computer waking up its com ports. To turn it off, go in to Device Manager and select that port: Properties > Port Settings > Advanced. Uncheck Serial Enumerator. Check Disable Modem Ctrl At Startup.
That should do it (for a Windoze machine). ---- 73, Mike Cizek W0VTT -----Original Message----- From: elecraft-boun...@mailman.qth.net <elecraft-boun...@mailman.qth.net> On Behalf Of Rip R Sent: Wednesday, 13 April, 2022 13:59 To: elecraft@mailman.qth.net Subject: [Elecraft] K3 auto transmit - W7RIP My K3 works like a charm and I have never had an issue with it. But recently after I turn the rig on or shortly after I turn it on, it will automatically transmit a series of 5 or 6 cw dashes evenly spaced (good fist) and at about 15 wpm. This will not occur again until the next time the rig is turned on. I do not know why it is doing this, but I would like to know. Ideas? 73s Rip W7RIP ______________________________________________________________ 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 mgci...@gmail.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
