QDX and the raspberry pi 5 running bookworm

 

Hi Everyone,?

I¡¯ve had an educational couple of hours trying to get Putty to communicate serially with my QDX from my Pi5. I¡¯ve ?followed the instructions in the operating manual and those in the GPS manual re identifying USB ports and changing the dial out permissions. However whenever I try to connect to the QDX, which is on ttyACM0, Putty disappears. The QDX works fine on my iMac and I have used the UF2 method on the Pi to upgrade the QDX firmware to the latest version .?

I wonder if anyone has experienced the same problem and overcome it??

For what it's worth there is an easier way to discover which USB ¡°port¡± ones QDX is on than the way Hans recommends in the GPS guide.?

Sudo dmesg > usb.txt

This puts the output of dmesg into a file called usb.txt. Open this file with a text editor and search for the string ¡°QRP¡± . This takes seconds and the computer does the work not you :-). Way easier than searching the output visually.?

Stay safe,?

or you can eliminate the file and then searching through it by using:

sudo dmesg | grep USB

You will get all of the lines in the dmesg output that contain "USB". You are sending (piping) the output of the dmesg command to the grep command. grep will print out only the lines containing "USB"

This assumes the user is running some version of linux.
 

Getting the port talking on a RPi 5 is the easy bit
Its /dev/ttyACM0
Make sure you put this in the PTT Method box too.
However
1 the Transmit audio source remains enabled meaning that it is not looking at the QDX as an audio source etc..
I also cannot get the Test CAT button to go Green.
The transmit button does however go red and enables the PTT.
As there is no audio you will see no power output.

Still not found a fix for this with Rpi5
?
If u open a terminal and type sudo putty
This opens a putty window
Go serial and enter /dev/ttyACM0
?
This opens up the QDX terminal with no problem and it can be controlled.

It seems WSJT-X is not yet functioning on a RPi 5
?
I might try running Win 11 on pi 5 and trying that

It is 2.6.1 downloaded direct from repository
?
 

Update
I reverted to a Rpi 4 and with that the CAT Test turns Green unlike the RPI 5
Pressing Tune on WSJT-x produces a signal using the RPi 4 but not on the RPi 5
?
Has anyone managed to get the RPi 5 working with any QRP Lab TX/RX

Hello Nick, Bill here N3GTY On the RPi5 I was not able to get CAT working also kept getting HamLib errors. Until I changed PTT to VOX on both the QDX and WSJT-X Software. This problem also existed on the QMX that I have. After that WSJT seemed to work no problem at all. I am not a fan of the Bookworm OS but for now that is what we have to work with. I really do not use WSJT-X I use JTDX which is a Improved version of WSJT-X. I did install it on my RPi 4-5 to test and it worked on both with VOX enabled. 73 for now de Bill N3GTY

Tanks Bill
Wsjtx with the version I used certainly has problems with the RPi5.
You ate quite right re PTT setting too.
?
The CAT still is only half working with the 5.
?
I was hoping to use the 5 so will try your suggestion.

I seem to recall trying it on a PC and Mcaffee did not like it .
