Paul is quite right, the 'compromise' HJ was a set of tolerance zones drawn on the energy sphere. It was designed to allow various 'production techniques' used by the BBC to still remain within the specification. The version used by us, the Reading group, was a kernel specification UHJ (not 45J BTW, actually more like 35J) and fell within the zones too. The IBA only used UHJ per our spec together with their brilliant (JH designed) 3 channel FM multiplexer for their broadcasts.
