K3 Line-In issues

I have been using my K3 with a SignaLink USB for some time without
issue. This last week I had everything working and then did a firmware
upgrade to the latest version. I now get nothing in or out of the
Line-In/Line-Out ports on the back of the radio. The microphone seems to
work fine, but I am no longer able to work digital using the ports on
the back

I have tried adjusting the gain by setting MIC GAIN to Line In and this
also has no effect.

I am sure it is a confused setting after the reflash of the firmware,
but at this point I am unable to locate the problem. Does anyone have
any suggestions?

Thanks,
-Corky

Don't forget to check the driver settings in your software.

Corky,

It is doubtful that a firmware upgrade is to blame. If it were the
firmware, we would have seen many reports of similar failure.
What did you plug/unplug since it worked last? A firmware upgrade does
not change settings in the K3.

Do you have the Line-in and Line out cables reversed? The Signalink
Line Out goes to the K3 Line In, and the K3 line out goes to the
Signalink Line in.

Connect the Signalink Line out to an audio amplifier and from your data
mode application, do a "transmit" - do you hear audio tones? If not
check your software and the Signalink.

73,

Re: K3 Line-In issues

Thanks to all for the suggestions and tests. Below are the results

MIC SEL was set to Line In to adjust volume - no effect so returned to
mid-range setting of 30
CONFIG:LINE OUT was set at nor 10 - the default value - did not change
this setting

I verified that the Line In and Line Out cables from the SignaLink were
in the proper locations and tested both external audio sources and sinks
- all worked fine.

I tested the K3 Headphone out - there was audio output. I fed the K3
Line Out to an audio mixer and verified that there was output, but it
was low.

I went back to the SignaLink and increased the volume using the front
panel controls from what had been 30% full to 70% full for both TX and
RX - I now had signal in and out.

Note: The SignaLink and the radio were physically connected exactly the
same before and after the firmware upgrade, the only difference was the
firmware change. The 30% setting is what I had been using prior to the
upgrade. Now I need to increase both the gain on the SignaLink and the
audio output from the computer to get to the same output level from the
radio as pre-upgrade so am wondering if the gain settings/cals have
changed. I should note that the previous firmware was likely 4+ years
old when I did the upgrade. Unfortunately, I did not either backup or
note the previous versions.

Thanks to all for the assistance,
-Corky
