K3 Settings for SignaLink USB

[David Bondy G4NRT]

I have been using digital modes for years and have a number of SignaLink USB devices which have all worked very well with a variety of rigs.

I am new to the K3 and have bought the Tigertronics cable and module set to allow me to connect a SignaLink USB to the rear Line In/Out and PTT connections on my K3.

I am able to operate the rig (via a USB to RS232 cable for CAT) and transmit JT8 signals (via the SignaLink) - I can see that I am getting out by monitoring Hamspots!  HOWEVER I am not able to get enough drive from the K3 via the Signalink USB to decode incoming signals.

Can someone who has this working please tell me what settings they have made to the K3 in order to drive the SignaLink? I have set CONFIG > LIN OUT  to 100 and I have rotated the Rx knob to full clockwise on the SignaLink but I am still not getting enough output to drive WSJT-X.  I am sure that I am missing something but I don’t know what because I would expect the LIN OUT setting to be more like 10!

Thanks in advance and 73,

David G4NRT

P.S. Please don’t bother to reply telling me to connect the rig to my PC sound card … it doesn’t have one!

I ask “why use a SignaLink with the K3?”

The K3 already has buffered Lin In and Line Out. Separate settings for in/out for each mode.

The one item to pay attention to is transmit audio level.  You should set the power out by using the Per knob on the K3 front panel.

Then adjust the audio to show 4 solid bars and flashingbfifth bar on the ALC meter.

David,

I think you should check the jumpers in the SignaLink.  Also make
certain the level controls for the SL soundcard are set correctly in the
computer.
Or simply use another USB soundcard - the K33 has built-in isolation
transformers.

Set the K3 LIN OUT level to about 10.

You apparently have a problem, but it may not be in the K3.  Plug
amplified computer speakers into the K3 LINE OUT jack as a test.  You
should hear the sounds.

73,
Don W3FPR

You have the Signalink w/the module or the one w/jumpers? Several of my friends have had trouble w/the Signalink w/the module, I have two Signalinks, both w/jumpers and don’t have any issues.

Many thanks to all of those who took the time and trouble to answer.  

I took the SignaLink apart and re-seated the module.  I also re-checked my ALC setting and all the others on the rig.  

I had come across a very useful document by Jason K8ZT and followed his instructions to the letter.  I also found the information by Don W3FPR immensely useful in setting up my ALC etc.

All-in-all very helpful and I am now up and running on WSJT-X with no problems.  I shall setup my FLDIGI next …

Thanks again everyone and very 73,  David G4NRT
