Audio codec

What radio.听听 Are drivers installed...听听 did you give microphone permission...听 maybe a screen shot of the sound card selection options?

You could also look at the other contests to see if they use the same exchange

RTTY-L is for FSK RTTY, using a keyed input to switch the carrier between Mark and Space frequencies. In RTTY-L the radio does not use audio (sound card) input. For any digital mode other than FSK RTTY, you must put the radio into DATA-U mode (or whatever Yaesu calls it).

Hello
Thanks Dave
on the FTdx101D I use RTTY-L mode
that's how it works with MMTTY for example
But I did the following manipulation
I replaced the fldigi_def.xml file with the one I used with the old version and there it works
I didn't find exactly what to do but it seems to work well, I'm going to save with a screen copy all these settings; but hey it's surprising
Thanks again

Hello

I'm trying to restart FLDigi after having given up a long time ago

Apparently I have the CAT, it decodes well but if I click on a macro to switch to transmission it sends a continuous carrier no modulation

听

I think it's a setting linked either to Hamlib or the internal sound card of my FTdx101D ?

Can you help me ?

Thanks

Dave W1HKJ, All,
Running multiple instances of fldigi version 4.2.06.20 on Win 11 very successfully, however when an instance is run for a long period of time I infrequently see some distortion creep in to the WF on one (sometimes 2) instances. When this happens, decode becomes degraded or stops only on the instance where I see the pattern like trace below:



From a concurrent iteration, that same signal looks like this:



Obviously it is not the rig or the OS audio system. It has happened for several versions back. It happens with fldigi using many different modems. Frustrating, because I have never been at the operating position when it does happen. It is always resolved by exiting the iterations that show the problem and restarting them. Everything seems to run fine for quite some time afterward.

1. Has anyone else seen this?

2. Any clue what might be happening?

Thanks and 73,

OK Daniel
so indeed I looked in the sound settings (Soundcard/Devices)
I checked the "Audio Port" option, in input I put the internal sound card of the FTdx101D
but
in "playback" I had also put the sound card of the Ftdx101,

I modified and put the audio output of the PC in the playback field
and indeed it is since this manipulation that now it works :-)

I still have to find some correspondents to test :-)

Thanks again

CAT, using hamlib, flrig,听etc., handles the PTT and synchronizing settings (VFO Freq, mode, filters, etc.).听 It has nothing to do with modulation.听 CAT has nothing to do with decoding.

Decoding and Modulation is based on audio and is independent of CAT.听 You can have fully functional audio with no CAT and fully functional CAT with no audio.

If you are receiving and decoding the received signals, then your Audio "capture" settings in FLDIGI are good.听 You are using the correct audio "microphone" and the volume/signal-levels are good.

If you are getting zero modulation out, then the audio output isn't making it to the rig.听 Verify the Audio "playback" settings and ensure you have the correct "speaker" selected (usually named "USB Audio Codec" or similar).

If you are running Windows 11, there is an extra set of configuration in the Windows audio "Sound Settings" that you may have to reconfigure.听 Under Windows 10, simply selecting the correct audio devices inside FLDIGI was sufficient, but under Windows 11, the Operating System may redirect the audio based on your OS configuration.

In the rig, you have to make sure that the rig is in USB Data mode so that it can be configured to transmit the audio over the USB cable.听 This is probably correct if you are receiving over USB audio.听 However, you also may have to configure the rig to use the USB input as the modulation source.听 Many times a rig is set to monitor the Microphone or an Accessory port for data mode operations (as would be the case if using a Signalink or other external source), and if your computer is sending audio over the USB cable, the rig has to be configured to use that audio source or you will get zero modulation (or modulation based on background audio picked up by the microphone).
