FW: K3 no power out on DATA

Ya know, I've got the same problem... but I've tried everything (all
combinations of Mic and Line-in switch and cable routings). When I was on
J6 a few weeks ago, I got RTTY going by running the audio right into the Mic
jack on the front panel and turning the gain way down. It worked but I sure
would like to get the "line-in" working. Any suggestions. BTW the same
cable plugged into the mic jack (on the Heil adapter) doesn't work on the
rear panel. Nor does anything else I plug into the "line-in". I have not
fussed with it because I had a work-around.

Mike,

That sounds to me as though you have the input set for MIC rather than line
in, or something similar.

First I would suggest using Line In and use DATA mode (AFSK A submode),
select Line In in the MIC SEL menu.
Set the K3 into TX TEST (or set the power down and operate into a dummy
load) - set MMTTY into transmit, then -- Adjust the line out and Wave
sliders on your soundcard to about 2/3 of full scale.
Then adjust the MIC Gain (now actually Line In) to illuminate 4 bars on the
ALC meter with the 5th bar flashing - ignore the conventional "wisdom" given
for data mode setup (no alc indication) - the K3 is different, the - the 1st
4 bars of the ALC meter do not indicate ALC at all, they are there to help
you adjust the audio level. The 5th bar indicates the onset of ALC

It's a long shot but make sure that L4 and L5 on the KIO3 Audio IO
board are not open. I've had L5 (in the ground leg of the Line In
jack) fail twice.

Re: FW: K3 no power out on DATA

In reply to this post by Dr. William J. Schmidt, II

*Bill,

Are you using any kind of "interface"? Many of them use attenuators to
drop the line level audio to mic level. For use with the K3 and its
line-in level, that attenuation must be bypassed. Until you indiacte
specifics about your audio source and settings (there are a LOT of
variations) we can only guess at the cause of your problem.

My best guess is that you are using an interface that is set for Mic
input, but are attempting to use the Line input of the K3. The mic input
is a very low level, and the line input is about 10 times as great.

Most interfaces have a jumper setting that will allow either mic level
or line level input. For use with the K3 line in, set that jumper for
Line Out level.

73,
Don W3FPR

In reply to this post by Joe Subich, W4TV-4

I might add that if L5 (in the return lead) is open, the signal will
find alternate paths and cause "funny happenings" rather than a solid
failure of no communications.

Re: FW: K3 no power out on DATA

In reply to this post by Don Wilhelm-4

The "primary" of the Line In isolation transformer is *floating* -
there is no connection to "ground" other than through the small
value (1000 pF) RF bypass capacitors. If *either* L4 or L5 is
open, you will get no audio via Line In and if you do, there is a
*serious* wiring error external to the K3 (and potentially inside
the K3).

Been there, done that, pulled out too much hair trying to find the
problem. Since Line In is transformer isolated, the RF chokes seem
to be a bit "overkill" ... Line In certainly showed no ill effects
when both were replaced by jumpers on an emergency basis.

By the way, I question the use of a 604 Ohm series resistor in the
Line In. The 604 Ohm resistors were replaced by 51 Ohm resistors
in Line Out to reduce IMD - one would think the same considerations
would be applicable at Line In.
