Hi,

Got a Raymarine C80 MDF and a M92650-S radar.

Problem: After 20min of scanning, echo rapidly fade to nothing.
- All diagnostic tests "pass"
- No error message displayed
- Inside radar dome, all look clean and ok
- Voltage at the radar 12.8volts while on shore power.
- All connections have been verified (back of the C80 and inside the radar dome)
- Magnetron has low hours count (2172 hrs)
- Scanner reset count: 0
- Magnetron current: 45
-Rotation time: 2463ms

Radar work again perfectly after a 20min cool down period (scanner in OFF position)

Resetting radar setting has not solve the problem.

I am a certified electronic technician...hoping for a lead to fix my radar on my small sailboat that I have sailed haft way around the world.

Regards,
