greetings all... i'm still a relatively new K3 owner but realize the functionality of firmware, especially with respect to DSP functions, such as noise reduction, is hotly debated, as it is a work-in-progress.
that said, i'm an SSB-only op and found that the 3.25 version of the Noise Reduction system, while awkward (in that you had to turn it off and then on again in order to have the FIR filters rebuild themselves) was actually useful... an ssb voice signal burried in noise could be helped with a setting of 2-2 or 3.2 without fundamentally changing the characteristic sound/overtones of the original audio. i was, therefore, eager to try 3.27, which came out tonight... the first thing i noticed is that pressing the NR button effectivelly makes my audio disappear almost completely. even with a very strong/clean signal against almost no noise, pressing NR regardless of the underlying setting, will cause the audio to go far far away... if i wait a bit (30sec?) some audio sometimes comes back, but it seems heavily filtered with no overtones (underwater bubble talk is how i describe it)... i dont know if 3.27 works great for CW, but for SSB, while 3.25 was somewhat functional, 3.27 is a non-starter. have build 2102, btw, in case there's some other issue that's causing this feature to work well with some rigs but not with others (ie, mine!) 73 robin (K9RDG) ______________________________________________________________ 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
