Re: [Elecraft] K3 Notch causes distortion on SSB RX

2014-07-28 Thread Joe Subich, W4TV
what you hear is a fast time constant on the auto notch. The faster time constant makes the notch respond faster but it also allows it to attack "purer" tones in the audio. The effect is more noticeable on strong signals with flat AGC curves where all frequencies in the audio passband are of si

At time like this I appreciate having "non-critical" hearing capability (deaf in one ear, ringing in both). My K3 sounds great under all conditions -- and no fan I have makes any noise :-) Phil W7OX On 7/28/14, 6:05 PM, Bill W2BLC wrote: Hello Sam in Ole Angelo, The distortion you are noti

I suspect, as Bill has suggested, it is AGC related. Dick - KA5KKT _ hard to describe, it's like the audio is getting chopped up, not sure this would explain it, but it's kind of like the sound of someone gargling being overlayed over the signal audio. A combination of that and

Bill I have found if i am trying to remove Cw i can use manual notch set to the signal and it seems the distortion fades away. I gave up using both auto-notch and NR on the k3 Gary Vk1ZZ K3, KX3, KPA500-FT, KAT500-FT,P3. On 29/07/2014 11:06 AM, "Bill W2BLC" wrote: > Hello Sam in Ole Angelo, > >

Hello Sam in Ole Angelo, The distortion you are noticing is very real and has bothered me to no end. It is discussed on a couple of websites, that I am sure the "experts" will jump in and tell you all about. I did some research on the subject and a lot of experimentation. I eventually found

What type of distortion are you hearing? Dick - KA5KKT _ I am noticing a bit of distortion on SSB signals when I enable the AUTO Notch. Is there some setting I can change to eliminate the distorted sound I am hearing now? -- GB & 73 K5OAI __
