On that diagnostic page there is reference to 'fiamodulator' and FIA Modulation Feed. FIA being Frozen Indigo Angel and Modulation being "In telecommunications, modulation is the process of varying a periodic waveform, i.e. a tone, in order to use that signal to convey a message" Transmissions, sirens, signals to send messages... is this going to happen at big weekend. Is that the destination unknown... am i taking a load of cak??? Anybody know anything about this diagnostic page?
