Hello Eero.
I cannot remember which issues contained the schematics for the Matrix-H
only variomatrix decoder, sorry.
Later, there were some simple mods to change from H to HJ.
Then, along came the Integrex linear decoder with shelf filters and
multi-system selection buttons, which I also built.
Later still, the IBA carried out some experimental 2.5/3 channel surround
sound broadcasts which were compatible with
existing FM stereo receivers. In relation to this there is a proposed new
type of demultiplexer for improved FM stereo or 3-channel
broadcasts by J. Halliday. This can be found in IBA Technical Review No. 17
of March 1982.

Many thanks indeed Eero.
You are welcome.
Actually, is the WW article with the practical schematics this one mentioned
in the refrences:
Heller, D: Surround Sound Decoders Pts 3 and 4. QS Variomatrix Wireless
World 82
(1488-9) pp. 57-59 August, and pp. 53-56, September 1976 ?
I have never seen that particular article? Anyone with a copy?
Or, was there ever a practical schematic released?
The basic H-Matrix decoder schematics were earlier released in a
Wireless World
article. That was actually a multi-format decoder.
