Hi,

        Apologies if you get this twice.

        Problems with transmitter 3 will need at least a day to fix (see
message from Manouch below).

        Therefore shifts are cancelled from now until Wednesday 20:00. I will
let everyone know tomorrow if there are further developments.

                                                                         
                      Cheers,
                                                                         
                                      Douglas
