Cat Control Linux Mint and Spotting

This weekend I played with the Linux Cat Control;

Issue: when I got the cat control connected. I opened WRL in Web browser/Log Book/Spotting(Pota). If I manually change the frequency on the radio; frequency would be updated on web page. If I select the call sign on the spotting page, the frequency on the radio would not change. I have had similar issue run on Mac; sometimes it works sometimes it does not.
Is there a certain sequence I need to follow; IE;

  1. Open WRL Desktop App

  2. Open WRL Cat Control

  3. Log into webpage via Cat Control (sometimes I will get a failure here)

  4. Connect radio USB

  5. Connect Radio in Cat Control

Set up: HP Laptop running Linux Mint Cinnamon

Installed: Linux Desk Top, Linux Cat Control

Radio: Yaesu FT710

Configuration

1. Hardware & Drivers

  • USB/serial cable connecting the radio to your Linux machine.

  • USB driver for your radio (e.g., “ICOM 7300 USB Driver”) — install it so Linux can communicate with the device worldradioleague.com.

  • On Linux, USB-to-serial adapters (like CP210x) appear as /dev/ttyUSB0, /dev/ttyUSB1, etc. You can check with:

    ls /dev/ttyUSB*
    dmesg | grep ttyUSB

  • Ensure your user is in the dialout group for serial port access:

    sudo usermod -a -G dialout $USER

2. Radio Settings

  • In your radio’s Operation Settings or General menu, set:

    • CAT Rate to match your Linux port’s baud rate (commonly 38400 or 9600 for stability) worldradioleague.com.

    • CAT Time Out Timer to ~100 ms (avoid 10 ms to prevent timeouts).
