Brian, My first response would be "use AFSK". My second would be "use a TinyFSK for FSK". But in response to your question, if you really want to key FSK directly from a USB-to-serial adapter you can use the EXTFSK plugin in MMTTY (<http://hamsoft.ca/pages/mmtty/ext-fsk.php>). This works with any USB-to-serial adapter. There is also a 64-bit version that supports other baud rates (<http://www.qsl.net/ja7ude/extfsk/indexe.html>) at the expense of heavier CPU requirements.
As distinct from AFSK, neither TinyFSK nor FSK keying with EXTFSK works via the USB cable used for radio control of the K3S (or K3 with KIO3B), which was how I interpreted the original question. They both require their own USB port, separate from the one used with the K3S for radio control and sound card audio. 73, Rich VE3KI K3KO asked: I seem to recall that the serial port needed for FSK generally cannot come from the run of the mill USB/RS232 converters. They can't operate at 45 baud/5 bit rate needed. See: http://aa5au.com/GettingStartedOnRtty.pdf This is old info and things may have changed. So what does a guy who has only USB ports do other than AFSK? I thought that was his question. ______________________________________________________________ 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
