Given its very odd that we have no radar traces - I thought CI radar could " see" us on SVR clearances " not above 1500 ft ".............
ATC never said he went below radar coverage. They said they lost him off radar which is different. May be wrong, but I think radar coverage goes lower than 2,300 off Alderney. Certainly the Aurigny flights to Alderney don't come off secondary radar, if they did they would not be tracked on say FR24. . Can't speak for primary radar.
This would imply he went down pretty close to the loss of radar contact.
edited to say, thinking about this further, Alderney is visible from North of Jersey, therefore around Alderney radar coverage must be at or nearly at sea level
