CAT and FSK/PTT must be on separate COM ports.73,Ed W0YK -------- Original message --------From: Nr4c <n...@widomaker.com> Date: 5/23/20 22:33 (GMT-08:00) To: k...@pa.net Cc: elecraft@mailman.qth.net Subject: Re: [Elecraft] RTTY Problems on K3 I think you need another program to make this work. It intercepts the serial port for the FSK/PTT and makes it all work together. I use 2-Tone instead of myth and seem to get by with just it and n1mm. For interface I use my WINKEYER-USB with the latest firmware. I use a “Y” adapter in the KEY line. The second line goes to K3/Acc2 FSK pin. “Diddles” go to FSK and “Dit-Dahs” go to CW. works well.

My problem is I cannot get RTTY to send/TX. I have made a homebrew interface with optoisolators for both the FSK line and the PTT line. I'm going from a separate serial port, pins 3 and 7, for FSK and PTT, to the Assy(15 pin) connector. To pins 1 for FSK, 4 for PTT and 5 for ground.> > When I run MMTTY I cannot get the rig to key. If I switch to SSB or CW and use the CAT line to work the PTT, no problem. If I switch to RTTY and try to use the CAT line it will not key the TX. I've tried a variety of setting in MMTTY and get no TX. I have a 1000MP set up with a similar homebrew interface and have no issues.> > Can anyone shed some help on me?> > 73 Bill K3SV> > ______________________________________________________________> 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 nr4c@widomaker.com______________________________________________________________Elecraft mailing listHome: http://mailman.qth.net/mailman/listinfo/elecraftHelp: http://mailman.qth.net/mmfaq.htmPost: mailto:elecr...@mailman.qth.netThis list hosted by: http://www.qsl.netPlease help support this email list: http://www.qsl.net/donate.htmlMessage delivered to e...@w0yk.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
