Fldigi and QMX successful???

 

开云体育

Has anyone successfully used the QMX with firmware 007 and later with fldigi??

Please either send me a message or reply on this forum. I really need to know if others are successfully using fldigi with it. I am not.

I'm just getting to wringing out the QMX after overcoming a few assembly issues.? It is NOT working here with fldigi 4.1.20 under Windows 10.?

Using flrig as a TS-480SAT, it's working fine with JS8Call.? Nothing particularly odd there that I haven't seen with the QDX.? Same setup with fldigi, I don't get sufficient audio out and, consequently, to power output.? On TX, the QMX's transmit indicator under the VFO indicator is two dots, indicating PTT activated and insufficient audio drive.? RX is good.

I've double checked audio device settings - they're the same here as with another rig with an internal, USB sound device - and twiddled Windows' exclusive access selections for sound devices to no effect.

Haven't figured it out, yet.? What are you seeing?

Dan,

Rig control as TS-480 or TS-440 should work with flidgi standalone, but not transmitting digital modes unless you are using firmware 006 or earlier. Later Hamlib versions also define the QDX and QMX.

If you use flrig then the 2.0.02 version will have QMX and QDX rigs defined so it's simple to set up rig control. Flrig also gives you a slider to adjust the output volume into fldigi or any other software if the default settings are not what is needed at the moment.

For me the QMX does not work with fldigi if I use firmware beyond 006. What I see is that fldigi will transmit/Tune once then never again until I power cycle the QMX then it will transmit once and not again etc, etc. Using firmware 006 ?all works normally except if you are using Olivia mode. Then either Tune in that mode once or use another mode once then Olivia will work normally as all the other FSK modes, the same as the QDX. Hans knows about it, but at this point no solution has come forth. So I recommend you go back to firmware 006 if you wish to do digital modes with fldigi.

I find it odd, but it seems as the people on this forum don't use fldigi for digital modes, ?or at least they do not reply to my request for feedback. Maybe mine is an outlier, but I doubt it.

Wow, the description of failing on the second transmission sounds suspiciously like the FT8CN issue here:??/g/QRPLabs/topic/100738548

It is probably the same problem. Sounds like we need Hans to sort it out.

73, Mike KK7ER?
 

Same here with linux and FLDigi.
Initial? PTT gives a very short burst of power out, then no modulation but keying continues to work.
reset QMX and above repeats.

This looks very similar to the issue with FT8CN?/g/QRPLabs/topic/100738548#107806

Indeed that sounds like the QMX issue I see. However it does not happen on the QDX, ONLY on the QMX.?

TRY reverting to firmware 006 and see if it fixes it. If so then you have exactly what I see with any mode with fldigi.

Hans, i wonder would it be tricky to route the incomming audio through the headphone output for digi mode when in TX? I mean something like a monitor output with volume setting in the digi interface menu. This might be a nice addition to dot, double dot and bar symbols and will nicely confirm what is being sent from fldigi/ft8cn via usb soundcard.
 

Sure, Peter. I added it to my list, that should be no problem.
