If you have checked the magnetron current and it is normal, then the issue with the X band radar not showing target echoes could be due to a few reasons:

1. Antenna: Check the antenna for any physical damage or corrosion. A damaged antenna can cause a weak signal or no signal at all. If the antenna is damaged, it may need to be replaced.
2. Transceiver: Check the transceiver for any damage or malfunction. The transceiver is responsible for transmitting and receiving the radar signals. If it is not working properly, it may need to be repaired or replaced.
3. Cabling: Check the cabling for any damage or loose connections. Faulty cabling can cause a weak signal or no signal at all. Make sure all connections are secure and the cabling is not damaged.
4. Signal Processing Unit: Check the signal processing unit for any damage or malfunction. The signal processing unit is responsible for analyzing the radar signals and displaying the target echoes. If it is not working properly, it may need to be repaired or replaced.

If you are not comfortable troubleshooting the radar yourself, it may be best to contact a professional technician to diagnose and repair the issue.

If the handset and antenna have been checked and found to be functioning properly, there may be an issue with the transmitter itself. It could be a problem with the wiring or circuitry, or possibly a malfunctioning component. It would be best to have the JRC World Marine Transceiver inspected and repaired by a qualified technician or the manufacturer.
