[Elecraft] K3 Audio instability

2014-03-20 Thread Mark Pride
 Recently noticed a problem with receive audio.  Hear a crackling sound while using the headphones and that noise does NOT vary as a function of the AF gain control.  It comes and goes, very random and very objectionable.  Almost like hearing instability in the audio stage of an old vacuum tube

Do you have the Auto-Notch filter on when this happens? If you do, try adjusting the AGC SLP down to about 6. I have found that using a setting higher up results in a very annoying warble effect. Bill W2BLC K-Line __ Elecraft
