I think I am correct in saying the BBC (H) and NRDC (45j) decided to
co-operate rather than have yet another two competing systems on
the 4-channel scene which at the time already had CD-4, UD-4, SQ and
QS in the arena. BBC/NRDC each modified their encoding "towards"
each other and called it HJ.

Tell me/us, is any of this H-stuff available anywhere? Has anybody tried
decoding it via the usual UHJ machinery?
Because as far as I remember, the encoding locus of H and UHJ are
compatible; in fact I seem to remember that UHJ was designed to be
compatible with Matrix H. So that an UHJ decode of H ought to work like
a charm, by definition. With UHJ decoders being much more easily
available than anything purely worked for H... ;)
