The K3 is not actually different or it would be violating the laws of physics. To make ANY radio work using narrow bandwidths on SSB is simply a matter of optimizing the placement of the filter passband in the voice spectrum (as Ed states above). The FT-1000MP, K2, Orion and many others can be made to work with narrow filters. I first discovered this on an MP I used in the late 90s: http://www.va3cr.net/va3cr2.net/markv/Troubleshooting/Filters.htm 73, Bill -- View this message in context: http://elecraft.365791.n2.nabble.com/need-some-roofing-filter-advice-tp6581353p6602111.html Sent from the Elecraft mailing list archive at Nabble.com. ______________________________________________________________ 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
