Very interesting. I went to that page and they want $30 for 5 days access!!
So, could you possibly advise me what changes were made to the Matrix? Richard The paper I just linked to ("System UHJ" by P S Gaskell, Sept 1979 <http://is.gd/MU9ijH> - which I now have a copy of) gives the BBC's then current encoding matrix for HJ, which is indeed different from the one I have for H. It doesn't give details of the "several" linear decoders developed, but gives a reference - which is to MAG's paper "Design of Ambisonic decoders for multispeaker surround sound". This implies that a UHJ decoder is expected. The paper then gives more details of a logic decoder.
