Line In not working ?

[Mario Lorenz]

Hello,

getting finally around to setting up my K3 for RTTY/PSK,
ie. hooking the line in/out to the computer, I noticed that
Line In doesnt work for me.

- Cables are OK (tested by plugging into MIC IN, the signal
is rather loud but there)
- MICSEL to LineIn, and line level have been tried up to 60
- Some time ago when I had my K3 open I had done all the mods re. audio
(mainly line out and the gnd mods) . I double-checked and all seems as
per spec...
- Using an ohmmeter to measure into line-in yields 630 ohm which looks
about right as per schematic, so I didnt short-circuit things...
- I updated firmware to 3.10

Could someone please confirm that Line In does work with fw rev 3.10 ?
Any further ideas ?

Mario

I've been using 3.10 since it was first available for testing.  DATA A
mode works fine.  Fifteen or so QSO's on PSK31 since 3.10 was first
made available for test says it's ok anyway.

Make sure your Line Out (at the PC) is enabled and has a level set. It
looks like you've checked everything else.  There isn't that much that
can go wrong.

Mario,

Check to make sure your input is checked in your OS or Sound Card software. That was one of my problems when I first set mine up. Mine wouldn't stay checked either until I updated the drivers.

Did you ever find a solution?  My Line in is also dead, it takes more than 15mw to get any tx power even at maximum line in gain. There is no ALC action until I hit about 15mw audio in.

I know the audio output amps fail (mine have a few times, with stereo plugs), but what is the most commonly failing component on the line in audio path?

Your setup may be different from mine, but when I find that I do not
have TX audio from the Line In, it is because I forgot to change the
mode from USB/LSB to DATA.  But I have mine set up to use the MIC jack
for voice modes and the Line In for data modes.
