When first seen here the usual Holme Moss Offering was the cross - white background and black vertical and horizontal bars - not sure of the official name - two versions - one presumably from the network and with a broad horizontal centre bar - and one possibly locally from Holme Moss with a narrow horizontal which could be used to lock the vertical synchronisation of receivers (it probably was the frame synchronising pulse circuitry within the generators which generated this - and didn't early CCUs have a switch which put out this test signal on the output whilst alignment was undertaken?)
