Missing part of scan

[RobV]

Hi, hoping someone can help diagnose my problem.

I've a 4kW open array (1934C). Last time I turned it on I seem to be missing part of the scan - see bottom right in picture below.
The radar has worked perfectly for years, its mounted on a flybridge arch with no obstructions.
The blank part of the scan stays if I zoon in/out.
The screen itself works fine, I can see AIS targets in the blank area, plotter works fine etc.

Thanks in advance.

It appears someone has configured the radar to have sector blanking turned on for an area. See the manual for "TX Sector Blanking". I expect that is what it is.
