Hi Everyone... thought I would provide an update.
I have now identified two problems on the Raymarine 240e :-
1) You cannot store a Coast Station MMSI into the "Phonebook" (these start 00)
2) If you make a DSC call manualy to a coast station (Coastguard) the following message is displayed
"SHIP-SHORE CALL NOT AVAILABLE"
This I found when tring to file a passage plan with Swansea Coastguard.
Raymarine have now realised the seriousness of these problems (after I contacted MCGA) and plan to realease a new version of software to resolve the issues within 2-3 after the radio has been tested again to gain type approval (I don't know how it got it with the current software)
Raymarine are then going to come and fit an updated radio to my vessel and check that all functions are working with my C80 - I've asked them to demonstrate the DSC location request feature that should display on the plotter.
I would assume that after this updates/swap outs would be available to other 240e owners so that they too can contact the CG via DSC!!
I'll keep you informed...
