Hector, I have listened to one of your audio files, the one you send to PD2DX (who was operating at PI4DX) last weekend. I know that my K3 just doesn't sound like that. It's close, but not quiet there. I have tried several settings with the help of K8OAZ pdf file on how to set the AGC. This has improved the radio a lot but it still prefer the sound of my friends IC 7700. Ik know the K3 can sound just as good but I still haven't been able to figure out how to do it. I find this tread very helpful to help me understand how K3 works and maybe one day find the right settings for me.
