I've done thousands of RTTY Qs in contests, sometimes scoring fairly well, and I've NEVER used FSK. If you're using a radio that allows you to put the AFSK tones in the center of the radio's narrow passband IF, there's no good reason to bother with FSK. The K3 DOES allow that. So does the FT1000MP (I know because I did it with both radios). Some radios do NOT (some Icoms, I am told, and probably others).
Some folks who don't know how to get audio cleanly from their computer to their radio manage to introduce hum, buzz, and distortion into the transmitted signal. But that is VERY easy to do properly, so that's not a good reason to do FSK either. If you DO have a problem with the computer interface, check out the tutorials on my website. http://audiosystemsgroup.com/publish.htm See especially the one on computer interfacing, and the chapter on Solving Problems in the Shack in the RFI tutorial. 73, Jim Brown K9YC ______________________________________________________________ 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
