David, Jim is spot on about wide dirty signals getting into your passband. The best you can do is play with the band width and shift to find a combination that limits the interference and makes the signal you are trying to copy, more copyable. For SSB contesting I will use the 2.1khz filter with a bit of DSP and also some shift to knock down the interfering station. I will say, the K3/S is far superior to the 756ProIII I had prior in this regard, from sharp filtering and AGC pumping. I can usually knock out a strong wide signal well into the passband I am listening, so that I can copy the weaker station. I am amazed though how close these days SSB contesters "overlap" intentionally into someone else's frequency, sharing half of the 2.7khz band width! That's one reason I prefer and enjoy CW and RTTY contests over SSB contests. Much more pleasing on the ears and temper! 73, Gene N9TF K3S 10057

I am an avid contester and when contesting thru the years (since 1978 and especially on 40 meters) have always had problems filtering out on my receive other contest stations who bleed over to my receive frequency their signals so I care hear the weaker stations coming back to me, mainly domestic contests. Thru the years operated IC 765, Omni 6+ and now the K3S. Still with DSP filtering, etc. I feel this is a way of life with contesting. Have had this discussion with many of my big gun contesters and we feel this must be a way of life with ssb contests. CW contests are much easier to filter out the side to side stations. My directional antennas on these bands help a lot but guess this is the way of life with ssb contesting. Would like other input from your experiences.
