1. Pay attention to propagation patterns: during the day, focus on frequencies between 10 and 15 meters; if recent activity has been low, you can also try 20 meters. At night, focus on frequencies between 20 and 40 meters.
2. Once set up, monitor the corresponding FT8 frequency and observe the reception results. Generally, if transmission is successful, you should be able to receive some signals.
3. Voice communication mode.
4. Read the instructions carefully to see if there are any settings that might be interfering with your device.
5. See if you can connect with some experienced colleagues at other companies (e.g., Eyeball) and ask for their guidance.
