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

**Installed:** Linux Desk Top, Linux Cat Control

**Radio:** Yaesu FT710

Configuration

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

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

**2. Radio Settings**

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