Not likely unless you can hear the 12k artifact (solved with the LPF upgrade for the DSP). Which reminds me...someone previously asked whether the LPF or the full DSP was necessary. The LPF alone solves the 12k artifact issue (if your hearing is good enough to hear it) and the full DSP board exchange adds extended low frequency response...mainly for ESSB. So it really depends on your situation. In all honesty, for my use, I cannot tell any difference in the 5 different K3s I've had (2 with the factory updated DSP and 3 without). It certainly is a mystery why some experience the mush problem and others do not. Luckily I'm in the latter camp but I'm watching with interest. 73, Bill W4ZV -- View this message in context: http://elecraft.365791.n2.nabble.com/Fw-CQ-WW-DX-Contest-CW-2011-Unofficial-claimed-scores-tp7060148p7063455.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
