I would like to make a few comments and ask some questions. This is by no means a put-down of the the K3, because I am not sure I am operating the rig correctly. After all it is a SDR and it is new.
During my first foray into SSB Contesting with the K3 during WPX, I found that I need either: 1. Understand more about the DSP and the controls for BW, Hcut and Lcut 2. Obtain a narrower roofing filter for SSB - like a 1.8 Khz filter 3. Or both. I spent some time trying to find the sweet spot in the radio for SSB using the 2.8 Khz filter. I don't think I found it. At least, I am not satisfied. I tried narrowing up the filter bandwidth to 2.4 or 2.2....some times 1.8. I tried shifting it up and down the bandpass. I tried to use High Cut and Low Cut depending on where the offending signal was coming from. AGC was on Slow with the standard settings. Used the RIT a lot It seemed I was always fighting some sort of side band splatter or stations close in on the frequency. Maybe it was just a crowded 20 meter band, but the same things happened on 40 meters. Do I need to go to a 1.8 Khz filter to give the DSP a break? Do I need to understand and play with the RX more to make sure I am doing it right. I would like to some feedback and comments on how other people set up their K3s for SSB contesting. I want to learn more about this radio. Lee - K0WA In our day and age it seems that Common Sense is in short supply. If you don't have any Common Sense - get some Common Sense and use it.
