hi all... elecraft/k3 newbie here (new owner of gently-cared-for #2102)... have read everything i can find, but can't dig up an answer, so this is my first post to the list:
i've downloaded the latest beta firmware and have read all the posts reciting joy and jubilation (my words) in connection with the operation of the Noise Filter... but i think i'm missing something... i work almost exclusively SSB and find that i'm listening to stations buried in the QRN... i -thought- this was where the Noise Filter was suppose to help, but when i turn on the NF and adjust it from 1-1 to 4-4 i seem to hear a somewhat filtered/somewhat distorted version of the input signal. i understand that the filter works automagically, but as i go from X-1 to X-4 it sounds like some kind of notch filter is being applied in increasing amounts, but not in a meaningful/useful way... then it goes from X-4 to Y-1 and the narrowing 'hiss' starts all over again, this time with a slightly harmonic distortion. on very strong signals i can sometimes find a setting (usually 3-2 or 3-3) that sharpens up the audio just a bit, but those signals usually are loud enough to blast through the noise anyway... what i'm looking for is help with the S2-S3 stuff. any advice or perhaps a pointer to an audio/video file showing the filter in (proper) operation? btw, the NB seems to work just fine as does the notch filter. many thanks and 73! robin (K9RDG) ______________________________________________________________ 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
