Ensuring proper switching timing between transmission and reception states is critical for clean voice communications. The manual outlines how to check the PTT line timing to make sure the RF power amplifier ramps down completely before the antenna relay clicks back to the receive path. This timing adjustment prevents arcing inside the SAT-100 Antenna Tuner . Diagnostic Workflows and Troubleshooting Verify voltages before connecting
