What to do if Nautel Transmitter shows High Reflected Power?
If the Nautel Transmitter indicates High Reflected Power, inspect the antenna and transmission line system for any signs of damage or de-tuning. If the antenna network seems fine and there are no obvious reasons for impedance changes (like icing), the combiner interface PWB (A12) might be the issue.
What to do if Nautel VS1 Transmitter reports All Power Amplifiers Inactive?
If the Nautel Transmitter indicates that all power amplifiers are inactive, and there are power supply module related alarms present, or an IPA Output Low alarm, follow the troubleshooting procedure for those specific alarms. If no power supply alarms are present, perform the PA resistance checks. If no problems are found with the PAs, or the alarm persists after replacing any damaged PAs, the PS distribution PWB (A2) might be faulty.
