Line out audio
Locked
 
|
"There is a Line Out level adjustment in the K3 configuration menu. Set it to
"NOR" mode (fixed-level output, does not change with AF Gain control) and set the output level to about 7 (pretty low). This avoids distortion caused by too hot an output level into the sound card." The previous was sent the other day thru the reflector to the list and i appended it for this message. The crux of my question, which is still unanswered is "why does the Main rec AF gain control affect the line out jack level when i've verified that in the config menu it is set to normal and the adjustment in the config: line out menu item only adjusts the Sub rec audio output. That is NOT the way it's supposed to be. It's almost like something is X-d up before the line out adjustment.

Hi Larry,
K3 troubleshooting is easier if you always blame the computer first. Do you have a built-in microphone on your PC? Are you using a speaker with your K3 (built-in or external) rather than headphones. Is it possible that the audio from your K3 speaker is being picked up by the PC microphone? Differences between main and sub could be explained by considering left and right balance adjustments in the PC. I did not dream this up. This came up a year ago when someone wrote in that his PC software was decoding RTTY before he even connected the line-out of the K3 to the PC line-in. 73, Mike K2MK

This has happened to me also. Some PC software can't handle multiple sound
cards very well. When I'm not getting the correct sound from the radio into the computer, I tap on the laptop a few times. If I see the extra noise on the waterfall when I tap, I know it is using the microphone input. 73 Jay W9IUF On Wed, Jul 7, 2010 at 9:49 AM, Mike K2MK <[hidden email]> wrote: > > Hi Larry, > > K3 troubleshooting is easier if you always blame the computer first.
