[Elecraft] help whit KDSP

[Oscar Castillo]

I have a K2 with the KDSP option, but it started making a popping/crackling noise a while ago. It wasn't that bad at first, but it's becoming more and more annoying. It's more intense on CF2 and CF3, less on CF1 and no noise on CF4. If i turn the NR on, goes away. On SSB everything is fine, no noise at all, only on CW

 my settings are

 CF1 - LPASS

 CF2   60  50

 CF3   60  25

 CF4   60  10

nr    97   30

Cn  G   0.0

CF  G   2.0

NR LEVEL 1

 Any clue where the noise como from?

 any recomended settings for the DSP?

 thanks a lot!!
