Problem with Test TX Data and ALC

I've been trying to set up my data modes using a SignaLink USB, which
I've used with good results with my KX3, with my K3. I do have the
correct K3 jumper board in the SL. I also have the SignaLink supplied
cables hooked up correctly. I can monitor digital signals just fine. I
can not get any TX audio actually transmitted, though Windows indicates
that the USB Codec Speaker is getting plenty of audio on TX. I've tried
to use the Test TX DATA routine within the K3 and get no ALC even when
Windows indicates that that line has full bore audio. I'm probably
doing something rather simple wrong here, but I can't for the life of me
figure out what it might be. In terms of experience, I'm an old hand at
digital modes having run them on numerous rigs, with various computers
and external sound card combinations over a number of years. I'm,
however, very new to the K3 as I just purchased it used at Dayton this
year, and I'm just now trying to hook it up for digital modes. Thanks
for any help you can give. 73 de Carl, N8VZ

Re: Problem with Test TX Data and ALC

Carl,

I figure you are using the K3 LINE IN jack, and when you used it on the
KX3, you used the MIC jack.
The Line In needs a much larger audio signal than the mic level that
your SignaLink is providing.
There is a jumper you can change in the SL box to increase the audio
output level - look for it in the SL manual.

I guess I need instructions about how to do this. Please see earlier
post I made about my inability to find proper menu item.

<<<Make sure you have selected the correct audio input source in the K3
menu. >>>

Perhaps I need instruction about this too, though I set MIC+LIN to ON.

If using mike input are you using VOX or PTT?

Using PTT via CAT and K3 does key OK, just no audio seems to be TX.

Re: Problem with Test TX Data and ALC

Carl,

You should be in DATA mode - specifically the DATA A submode on the K3.
Do not use SSB mode, even though it will work, that just "muddies the
waters".
For that mode, do not set MIC+LINE on in the menu - set LINE IN only.
This is a per mode setting, so if you want to use MIC+LINE for voice
modes, it will stay.
With LINE IN set as the input, the gain adjustment is the MIC Gain control.

You will likely find the best result if you set the SignaLink for high
level output. That will give you better control with the LINE IN gain
in the K3 set for something mid-range rather then using a high setting.

73,
Don W3FPR

Thanks for your help. See my last post on board. Everything OK now.

Re: Problem with Test TX Data and ALC

In reply to this post by Don Wilhelm-4

Thanks. Yes, everything's working now. I guess my problem was the Line
Gain at zero and not knowing how to adjust it. Reading the manual and
having you point me to the source of the problem were the keys. Thanks
again! 73 de Carl, N8VZ
