Continued from: [CQ-Contest] SOME THOUGHTS ON USING THE K3 ON SSB Reading these messages, I decided I should try adjusting the offset for my 2.8 8-pole filter from the normal 0. I have been getting good audio reports, but not "excellent".
Listening during adjustment, I found that as I reached -.20 some high harshness was reduced. I thought that would be good, as I often find myself cutting back the HI passband to get a similar effect. Then I got on the Sunday Elecraft SSB Net. I couldn't get many opinions because propagation was poor, but I had Phil NS7P give me his opinion. He reported the least distortion around offset -.20, and clearly an improvement over the 0 setting. So that's where I have it. It's an easy test to make, since you can transmit with the CONFIG window open. Ever curious, I thought to play with my 2.1 filter offset (just for receiving of course). I never liked listening to SSB with it because the highs sounded harsh. As I turned it from the normal 0, down past -. 20, it started to sound better. I preferred around -.40 until I checked it on a weak CW signal. It was making it weaker in comparison with the other filters. So I compromised and set it at -.27. I'm happy with that! I think this is a good discovery! Maybe it's something the factory should look into?
