"I wonder if someone who has significant WSJT-X experience would like to pontificate of the real benefit of squeezing out another KHz of bandwidth out?"
Certainly no expert here, but the slightly wider bandwidth does allow a WSJT-X user to copy the full suggested sub-bands for both JT65 and JT9 at the same time. While, to your point, that might not be the wisest thing to do on 20 meters during a contest when folks tend to ignore the "suggested" band plans, many times on the WARC bands there are no strong signals to worry about. So the bottom line is when it is appropriate, you can use it, and when it isn't you can always shift to a more narrow roofing filter and focus on one mode vs the other. It's simply an option. The ability of JT65 and JT9 to decode signals below the noise level is the closest thing to magic that I've come across in my ham experience, allowing extremely low power communication to be accomplished with sub-optimal antennas. I can work Australia, half way around the world, regularly with 0.5 watts of output But it isn't magic, just applied mathematics. And there is no denying there is something almost magical about decoding a signal that you can't even hear. 73, Bob, WB4SON ______________________________________________________________ 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
