IDENTIFIED It's the UK GOV/MIL "WinDRM51" variant, supposed idle only, seen on many freqs in the past, for unknown purpose yet. But link between UK & Cyprus has been found some years ago. Credit: Linkz --Cartoonman (talk) 08:59, 18 January 2016 (NZDT)

It is a special case of OFDMOrthogonal Frequency-Division Multiplexing, using only one of every two symbols.
