K3 and FLDigi

I've been using CocoaModem, but since Chen isn't supporting it anymore, I feel the need to move on.

I'm trying to get fldigi working, hopefully with RUMLogNG.

It decodes CW but not RTTY, and doesn't transmit either. I suspect off-line would be best.

Re: K3 and FLDigi

But that’s a problem of probable general interest and the results should end up in the archives.

Re: K3 and FLDigi

David, you may be correct, so I will repost to the list what I sent to
Mike earlier today. It did not entirely correct his problem, however.

Mike,

I'm pretty new to digital, but am using Fldigi, so I'll give it a shot.

In Windows, I right-clicked on the speaker icon in the lower right
corner, then selected Sounds. On the Playback tab, I selected Speakers
set to my USB Audio CODEC; likewise, on the Recording tab, Microphone is
also set to my USB Audio CODEC.

In Fldigi, in Config\Soundcard (I'm using an audio interface: Tascam
US-100), I set Audio\Devices by checking PortAudio, then selecting the
Microphone (under Capture) and Speakers (under Playback) that my sound
card is set to in Windows sound - USB Audio CODEC.

Next, in Fldigi in Config\Rig control, choose the Rig tab, then Hamlib.
In Hamlib, check the box in front of Use Hamlib at the top. In Rig
choose Elecraft K3/KX3 (Beta). In Device, choose your com port. Below
that, set the Baud rate to 38400. On the left side, check the box for
PTT via Hamlib command.

Finally, click Save at the bottom, then Close.

Hope that helps and works for your set up.

73, Dave W8OV

You're right David. when I find the secret code, I'll post it to the list. I just didn't want to clutter it up with the prelims.

In what way doesn’t it work on RTTY? Just not decoding? That could be an upper/lower sideband issue. After properly tuning an RTTY signal, click the RV (reverse) button on the bottom right and see if that corrects the decode. If so, you need some properly set up the K3 for decode on the band in question, or use fldigi to get it right (DATA vs. DATA-R) in the box to the upper right of the frequency readout.

Of course, it could be other issues, but that’s the first that comes to mind.

Generally data modes all operate on USB but the K3 doesn’t necessarily follow that, depending on your settings. I’m not sure about RTTY, whether it is USB on all bands or not. But anyway, changing the RV button will tell you if that is the issue.

Dave suggested the HamLib option in fldigi as follows
Next, in Fldigi in Config\Rig control, choose the Rig tab, then Hamlib.
In Hamlib, check the box in front of Use Hamlib at the top. In Rig
choose Elecraft K3/KX3 (Beta). In Device, choose your com port. Below
that, set the Baud rate to 38400. On the left side, check the box for
PTT via Hamlib command.

Alternately, you can elect not to use either Hamlib or rigcat, but simply use VOX in the K3. This frees the cable for something else, but it does disable frequency tracking.

Jim,

I don’t think I gave bad advice, I said I wasn’t sure about RTTY, right? That’s an invitation for someone more knowledgeable to jump in.

But as you point out, RTTY is different from the other data modes, which use USB (actually DATA on the Upper Sideband).

While factory defaults may be right on the K3, since it stores last used, it is often very easy to get it changed and not realize it. I know I had problems with a single band in digital and it turned out that that particular band was using the wrong sideband presumably due to my changing it at some point in the past.

Also there is the issue with is the person using direct keying or AFSK which are different settings. fldigi would probably be using audio tones not direct keying although I think that’s possible. I am not an RTTY operator.

Some digital modes operate upper or lower but I believe some must be upper. I think this is addressed on W1HKJ’s website.

Having been on RTTY from 1963 through present with machines as well as computers now, the convention for RTTY has ALWAYS been LSB no matter which band you're on and the K3 treats it that way. Not all multi mode programs do it right though as apparently the programmer didn't thoroughly check the convention for the different modes. PSK-31 works no matter which sideband you use but I don't know about the other modes such as PSK-63, Olivia, etc., as I never use them.

Re: K3 and FLDigi

With a lot of help from people here, it's working.

I'm using an iMic USB sound card. Sound setup in a Mac is tedious. Adjust the level to 3 or 4 bars on the K3 ALC meter. I was unable to get the flickering bar. My slider took me from 3 bars to 7 with the least I could move the slider.

In fldigi, select the Configure menu item, then Rig Control. On the dialog that appears select the Rig tab, then the Hamlib tab.
For Rig, choose Elecraft K3/KX5 (Beta).
Device, choose the serial port that connects the 'puter to the K3.
Baud Rate to 38400(must match what the K3 is set to), 1 stop bit.
Sideband is Rig Mode
Check Use Hamlib and PTT via Hamlib command. Click Initialize, and Save.

I don't like this arrangement, because I want my logging program to connect to the K3, but if this isn't set, then fldigi doesn't generate any tones. There has to a way to key using VOX.

Select the Audio tab and set your sound IO. Click Save.

Operator info was filled in. Click Save and Close.

Click Op Mode and choose RTTY, then your RTTY flavor. That sets the box in the lower left corner of the screen to RTTY. Don't click on that box and change anything there.

There is a box and down arrow just under the frequency display. Set that and it changes the mode on the K3, so I choose RTTY. The DATA sub-mode on the K3 is AFSK A.

Any further info welcome!
