K3--Digital Mode Question (New Tricks...Old Dog)

[Dick Roth]

Finally waded into digital modes with FLdigi, but have a K3 question
regarding Line Out control.  From what I could tell from the manual,
Line Out to my PC ought to be a level adjusted by Config: Line Out.
However, each time I turned down the AF control, the signal to FLdigi
went away.  What am I missing? (I'd like to operate without the constant
whine of PSK ringing in the shack.)

Any help in clearing this up will be much appreciated!

Maybe you have the audio cable connected to the phones or speaker jack
on the K3, instead of line out?

Or maybe you have CONFIG:LIN OUT set to =PHONES? Tap '1' to turn that
off whilst in CONFIG:LIN OUT to toggle that.

Or maybe the computer is actually taking audio from a microphone
instead of its line in, and you're picking up the RX audio
acoustically? If you clap your hands, does it make a pattern on the
waterfall? ;)

Dick, from the menu parameter section of the manual: (see second paragraph.
Try tapping "1" while in the menu, at the LIN OUT parameter).

LIN OUT: (NOR 010) Sets the LINE OUT level. LINE OUT connections go to PC
soundcard inputs. Settings above 10 may result in overdrive of the soundcard
or saturation of the KIO3's isolation transformers; monitor signals using
the PC to avoid this.

Note: Normally, LIN OUT sets a fixed-level receive-only output for main/sub
(L/R), compatible with digital modes. Tapping 1 switches LIN OUT to
=PHONES, where the line outputs match headphone audio, audio level is
controlled by AF/SUB gain controls, and both RX and TX audio are available.

GL,
Bruce, N1RX

Iain and Elecrafters--

Thank you for your responses and guidance!  Iain hit the nail on the
head with his third possibility...audio into a microphone!  I was using
a never before used sound system built-in to the motherboard and had the
incorrect gain control (microphone) turned up instead of the Line In.
