Regarding UHJ channels: I should have said, that in my (limited) experience 'UHJ' means either -all the HJ's (the top four rows in the Wikipedia table) or - what is/was known as BHJ (i.e. two channel).
Others may have different experiences ... and almost certainly based on a bigger sample. Anyway, a typical case of the generic term coming to mean the commonest specific example .... So: UHJ has no Z (if UHJ is BHJ) or: UHJ can have Z (where PHJ is one of the HJs that comprise UHJ). Another term for all the HJs is _IIRC_ 'C-format'. As I said an alphabet soup ...
