Check the battery voltage with a multimeter or replace it with a known-good battery pack. | Directly implied by battery importance | | Intermittent or no signal | Faulty antenna connection, damaged antenna, or configuration issue. Check the antenna cable and whip for physical damage. Ensure the radio is set to the correct frequency and modulation mode (USB/LSB/AM). | Reasoning based on RF troubleshooting | | Power module failure | Internal power supply unit (PSU) failure. Repairing these modules is extremely costly (e.g., a quoted repair cost of €13,500 for a related Thales radar module). Requires depot-level maintenance or replacement by a certified technician. | | | Unit not communicating after programming | Incorrect firmware upload or configuration error. The programming process is complex and uses specific utilities like "LoadROM". Revert to a known working configuration or seek technical support. | |
