Hello,

I am wondering what the current operability status is between FT8CN and QMX (1_00_017).

Mike KK7ER reported on FT8CN and QMX back in July 2023 (#105559) with regard to 1_00_005.

Four things that got this working for me OM:

1) Select the Kenwood TS570 at 9600 baud, 8 -n-1, usb plus cat in the Settings window of FT8CN.

2) Be sure to set to "Lockd TX=RX" immediately to the right of the "Audio freq" entry in the same Settings window.

3) Set the "Signal output strength" to "100%" using the slider control which appears when you hit/select the speaker symbol on the right side of the/any FT8CN screen.

4) On the QMX set the MENU -> DIGI INTERFACE -> VOX to "ON".

Finally go ahead and restart the FT8CN program with the QMX running in DIGI mode. FT8CN will ask you to select the serial port. DO THAT and you should be a happy camper.

Wonderful. Thank you Bob.?

I am able to use CAT (not VOX) with QMX firmware 1_00_17 and FT8CN 0.0.92.
I'll check the rest of the settings this afternoon and post them.

Here are my settings.
I was surprised that I had forgotten to change the rig back to TS-480 from Yaesu FT-450(D).
It appears to work with either setting.




It transmits fine either way.

FYI.
I just closed the ticket with FT8CN.

It would sure be more satisfying if we had an explanation for what changed to resolve this.
But at least it is resolved!

73, Mike KK7ER

Thanks for those Mike. WRT Audio output setting in the setup menu, what about (1) Bit depth and (2) Sample rate?

Jim
VE4BWG

Bit depth:? 32-bit float
Sample Rate:? 12 kHz

73, Mike KK7ER

Thanks Mike.?

Unfortunately, I cannot get QMX to work with FT8CN.

* ver 0.92
* QMX firmware 1_00_17
* QMX settings all default (factory reset)
* FT8CN settings exactly as shown below

QMX display shows the two spots indicating too low audio volume during TX. However, audio volume on my Android phone is maximum and also 100% in FT8CN.?

Setting to Vox in QMX and/or FT8CN does not help.?

Do you have any idea, what I could try next?

The QMX will not work with FT8CN.

Hello Frank,
some phones allow to set the audio output higher than 100% and warn that
this may damage hearing.
With many phones the output for headphones or in-ear phones is a lot
lower than the line output of a desktop PC.
In that case the only way is amplifying the audio output. But that adds
another small box to the setup and defies the purpose of working QRP and
portable with the phone - unfortunately.

I just made a contact on it with a samsung s10e.? I have the QRP QDX selected as my radio. I have USB-C connected directly from phone to radio.

Thanks, Philip,?
I interpreted this posting by Mike who clearly says it works for him:

/g/QRPLabs/message/119130

Thanks, Eike,?
I was talking about audio sent by USB-C from my Android phone with FT8CN to the QMX. So there is no analog line out, but digital audio (my interpretation).?

@Mike KK7ER
Maybe I am missing one of your settings?

73 de Frank DD4WH?

Please refer to my message in this thread:

/g/QRPLabs/message/119105

That did work for me on my cell-phone. It has been used on several outings with complete success.

PLUS ** I am in the process of installing using the same directions on a brand new Android tablet a.t.m. (I am NOT sure when I will be able to test using the new tablet on-the-air, but IF I run into any issues or changes; I will be sure to let this group know !)


PLEASE NOTE: I offer up 4 things to check/set in my earlier posting referenced above. The first three are in the ft8cn program itself, and the last one is on the QMX itself.
**** So....PLEASE be careful about this as some of the messages, in this thread, have indicated some confusion about this.

Thanks Bob!

It was exactly your 4 instructions I was following. Vox for QMX, CAT in FT8CN. But still, no transmit.
I used the latest firmware with default settings, to ensure that I used "reset to factory settings ".
Thus, I suspect there are other settings in your QMX that differ from the defaults. And it would be very helpful to know what these are.

These are likely candidates, maybe? Could you tell us about your settings in:
Rise threshold 80
Fall threshold 60
Min cycles 1
Min samples 480
Discard samples 1
CAT timeout ENABLED

Thanks very much in advance!

Hi Frank,

These are my settings. QMX is default for digital.? ?USB-c to usb-c phone to QMX.? ?Volume slider in the app all the way up.

@Frank DD4WH

Groups.io seems to have hidden my response so I'll try again.
You wrote: Perhaps.? I made a little video showing the settings and showing FT8CN working as expected with my QMX.


Note the OTG adapter shown in the video was required for it to work for me.

I'll leave the video up for a few weeks but will eventually have to delete it to make room on my Google Drive.
