Good afternoon all,

I ordered my QMX a couple days ago and I am super stoked to try it out - Looks like another extremely impressive kit!? The but about buck converters and nudging the switching freq to move QRM was a really clever bit of engineering...

Anyways, I like to operate portable and often use an Android app (AndFLMsg) that can be used to send digi modes in AF over a 3.5mm audio jack.? With a radio with VOX you can run digital modes from a smartphone or Android tablet.

If the QMX could run VOX with audio input from the mic jack instead of the USB-C it would make it a cinch to run in the field.? Is this a function that it supports now, or is AF for digital modes only allowed through USB-C for now?? If so, is this a potential future upgrade?

Not a direct answer, but I use FT8CN on Android via usb with a QDX successfully and am assuming it'll also work with the QMX when I finish it. Clearly, that doesn't help with other digital modes, just my 2p worth!

So your android is capable of running the QDX as a sound card?? Interesting...

With a USB OTG adapter the QDX and QMX appear as sound devices on Android. Both work for me.?

Hello Mike,

I've been trying to connect my QMX to my android phone to use FT8CN, however it doesnt appear on my phone as a USB device. Could I ask if you have done the USB-C mod to your QMX for it to work? Or is there some settings i have to do? I've enabled USB debugging and cycled through all the USB configs(MTP, Audio etc.) and it doesnt detect. I'm using a Huawei P50 Pro, my cable is OTG compatible.

Hello Chuck,
I just noticed your message. I am trying to get my QDX-M to work with andFLmsg on an android phone, so a different application from you. I might however be able to solve the first part of your problem of getting the phone to recognize your QMX.
I obtained a terminal app from the Play Store, I used "Serial USB Terminal". Once the app was installed and I had connected by OTG cable to the QDX, I opened the app menu, selected USB devices and found there the QDX device. Selecting it caused the app and QDX to connect. I then selected the radio app I wanted to use (in my case andFLmsg) and I was able to communicate and send text to the QDX for transmission using Olivia (in VOX mode). I am still having problems receiving audio back from the QDX to the phone, but I figure I am more than half-way there!
Let me know if this works to establish communication between your phone and QMX.

I would like to access the QMX with my Android phone via terminal.
This is no problem under windows or Linux with putty.
Android terminal programs, for example "Serial USB Terminal" recognise the connection. I cannot find an 80 x 24 character window setting in this terminal programme. The display in the smartphone is therefore unformatted.
Does anyone know a solution with a USB terminal programme under Android?

Mike, you're able to use the QMX via FT8CN? Please tell me or post a picture of your exact setup. I know just about everything is a workaround right now, but I'd like to copy it! My POTA is currently limited by the poor battery life of my heavy, *old* laptop.

Chuck,

I'm so sorry that I missed your August 14 message.
I have groups.io set to digest mode and when I get busy sometimes messages slip through.
I did not make any modifications to the QMX or do any special configuration.
I hope you solved your problem.

Hi Mordan42,

I didn't have to do anything special.
I just plugged the OTG adapter into my phone (Pixel 6) and ran FT8CN.
Here are some pictures of the config.






The QMX still fails to transmit after the first successful transmission.
Hopefully Hans will fix that soon.

I have also been playing with my QMX and FT8cn. I have had modest success. Currently I'm using my old cellphone a Samsung. To get things going I needed to increase the audio levels otherwise I got the 2 horizontal bars under the "A" marking the VFO selection.

Now I have another problem. I am decoding well but when I answer a CQ the QMX transmits my request and then as it terminates the transmission it throws a fit and activates the "S" on the protection circuit. SWR, battery voltage, power out etc are all okay. I single transmission followed by "S" is all I get?

Any thoughts??

Mike,

Thanks boss! Every little bit helps. When that does get fixed, I'll be a POTA machine. I drive a LOT for my job, and pass every state park in central/north Louisiana at least twice a week.

Here is a brief description of how to configure the terminal programme "Another Term" on an Android (ver. 13) smartphone.

Kevin, K3TL, helped me with his description and the screenshoots.

Connect the QMX (or QDX) through an OTG cable to the phone.
Be sure to power up the QDX or QMX before attaching to the phone so the filesystem on the device doesn't get corrupted.
If you have FT8CN or AndFLMsg installed one of them will popup a window asking if you want to connect. Cancel.
Open Another Term and create a profile to start with. Press +
It should pop up a dialog box. There you have to configurate:
UART
80 cols - 24 rows
9600 Baud

It works well on my Samsung A51, Android 13.
