Operating Frequency Pane

Victor L. Gagliano <wa2arq@...>
 

Dear Group,
Can someone go over the steps to have Fldigi display or change the Frequency being displayed?
I must be missing something in the setup.
Tnx,
Vic

Flrig is the preferred method of transceiver control.
Make sure you have Enable flrig xcvr control with fldigi as client box checked in Fldigi configuration.

I found this forum while searching about what I believe is the same issue (rig is IC-756Pro), but it also happens when the rig is off and there's no audio coming in, where the audio level (green bar) is always at full.
 
Today i compiled fldigi 4.0.18 from source to see if it still happens as it did with the version in the ubuntu package source, and it still does. Attaching a screenshot that shows what i see after switching on the rig and enabling the FSQ monitor. Notice the signal level is always all the way up, regardless of whether the audio input level is on or not, and so I can't enable the squelch at all.
 
To note, in any other mode i try the level is reflective of what is expected from the rig and the squelch works fine, but this only seems to happen in FSQ that I'm aware of.
 
I've also looked at the help file and found a white paper on using this modem but not seeing any answers.
 
Is there a setting I need to check for this?
 
Thanks so much and 73, let me know if i can provide any further details or try a suggestion.

Throttle the audio hose ...  your drowning the application.  Everything on your screen shot says too much audio



Both signal indicators at max.
Diamond to the left of the AFC button is RED.

What OS are you on?

Hi Dave, great to talk with you.

I'm running Kubuntu 18.04 x64, and Pulse is handling the audio. I hadn't caught the red diamond after messing with the input earlier, so ended up finding 24% on the pulse slider is the happy green spot (attached). Took it all the way down and it goes black naturally, then found the green spot from there. 

Looks like it still shows full for FSQ though -

I only had a few minutes to check it out but later on i can try to find a sweet spot somewhere in { black < x < green } if that's the right answer.

I am used to the alsamixer sliders for digi stuff, and i can also try tuning those - I notice with pulse in the middle the alsamixer doesn't seem to have a linear effect on what eventually happens, so it may just take some tinkerizing, as I realize FSQ is a different animal than other modes.

Thanks for the reply! I'll report back once i get to take a few more swings at this.

Re: Yaesu FT-991 and FSQ

I do not recommend mixing pulse and alsa mixers.  Use the pavucontrol for pulseaudio mixer and audio stream virtualization.

Also, it is not usual to call CQ using FSQ.  Set up a beacon, or simply transmit an empty (no text, ENTER) frame.

Thanks, Dave. I was just trying to invoke a transmit as part of testing with dummy load, so we will bone up on the protocol once i get the interface looking good.

As for alsamixer vs pavucontrol, should i just keep the alsamixer ones at full or zero (as appropriate) and then trim using pavucontrol, or just ignore alsamixer altogether?

This is the only app for which i use pulse so bit of a learning curve here

Re: Yaesu FT-991 and FSQ

OK Just to chime in here.

I have pavucontrol up and running. I set the record audio for audio codec at 80%. The Diamond is black and the sound level indicator is pegged. No Squelch opening. For a test II drove the audio level to 0 in pavucontrol, the waterfall started to fall away to black. The audio level to Fldigi stays pegged at the top. Never varies. And the diamond is always black.

If I use the signalink everything works as advertised. No problems. With the FT-991 internal sound card, problems.

OS is Ubuntu 18.04 LTS. Under the FWIW column - I don't remember using FSQ when I was at Ubuntu 16.04 LTS. So I am grasping at straws here.

Hi WT,

I just wanted to report that I don't see that problem on Ubuntu 16.04 LTS here with FSQ.  Rig is a Kenwood TS-590S and I'm using Pulse Audio.  I've been hearing bits and pieces of problems with 18.04 so I haven't pulled the trigger yet.

Looks like the green zone with the pavucontrol input is around 11-14%, that's with the capture slider all the way up, or else with capture at 50% then it's a wider range naturally.

But even with it turned down completely black it's showing as full signal on the green bars there.

Just for grins I just tried all this on Windows and FSQ works as expected with my rig and interface, so really looking like ubuntu 18.04 is the oddball platform for whatever reason :/

Re: Yaesu FT-991 and FSQ

W. T. Jones
 

Thanks Ron and Al...

Yes I am beginning to believe this is an 18.04 issue as well. I fired up a windows 10 in VB and it worked with the direct connection to the USB device.

Going to start up a real copy of Windows 10 to test it properly.

Another nutty 18.04 issue is that when doing an Alt-Tab to work through programs Flmsg shows us Fllog in the banner listing the active programs.

I hope that 18.04 is not going to end up being a problem child.

Is there a way one can go back to 16.04 if you have
performed an upgrade to 18.04? Rather than reloading
from a CD/DVD.

Re: [linuxham] Checkboxes show no X in Linux Mint 19 MATE 64-bit #build

Here is an alternative that does not require changing the fltk source.

Add this line to src/main.cxx, just before

int ret = Fl::run();

change to

    Fl::set_color(FL_SELECTION_COLOR, 0, 0, 128);
    int ret = Fl::run();

I had so much trouble with FLDIGI after I upgraded to Windows 10 that I reverted back to 7!

FSQ Send Alert does not respond with ack in 4.0.18

Bill - km5vz
 

Greetings, 

With FLDigi 4.0.18 installed on Debian Slink and Raspbian we have noticed that the ``Send Alert'' (|} function does not respond with an ``ack'' when the target operator closes the dialog box.  We did not have a Windows or Mac system to verify if they work.  This is a useful function that worked back in the 3.x loads.  Here is a screen dump of the current 4.0 manual:

  • callsign|message (Send alert) Addressee station starts to print. Alert pop-up box containing message is placed on the screen. When the operator closes this dialog, a response transmission is made: origin_callsign Alert ack
Is this a bug or an oversight with the manual? 

Thanks, 

Bill
