The British Institution of Radio Engineers has been studying postwar developments in wireless and television.
In a report, published to-day, it foresees nationwide television, coloured stereoscopic television relayed to cinemas, a big increase in broadcasting
by the introduction of short-wave transmission, sound films in the home,
and increased popularity for home recording of gramophone records, which,
it Is suggested, may be used in conjunction with the cine-camera, and wireless telephone calls to New York or Calcutta as reliable a local call. All these developments are, in the opinion of the Institution, dependent
on State control of the ether, though not a monopoly of radio
entertainment.

The first stereo FM radio I heard was in the late 1970s. I worked in
the audio visual room at school as my prefect duty in the 6th form and
there was an FM tuner which was used for recording some educational
radio programmes. It was quite a revelation to hear the difference
between stereo FM on a high-quality tuner, amplifier and speakers with
a roof-mounted aerial, compared with mono FM on a normal radio and
small speaker with a telescopic aerial.

Didn't some VHF FM broadcasting begin experimentally before WWII in
the US? But the first commercial licence was issued in 1940. By the
end of 1941 almost 400,000 VHF FM receivers had been sold.
It was put at the top end of the then VHF band because no one else
wanted those frequencies and TV was using the lower VHF frequencies.
Armstrong's book is quite a good read.

What, "real" stereo on FM? Or using the TV sound as one channel and
radio as the other?
(*) If 192 kbps MPEG is good enough for purists ;-) Is the sound
quality of AAC sound on an HD channel significantly better than the MPEG sound on an SD channel? Is it worth watching on HD rather than SD for
better *sound*?

The second
I'd not thought about it until now, but the results of them attempting a Radio 3 / BBC 2 simulcast these days would be "amusing", given the
inevitable time offset between the two channels. At the time of the
Queen's funeral, when BBC1 and ITV were both showing identical feeds,
there was a time offset of a second or so between the two.
Even worse would be the delay between R3 FM (analogue, so no delay) and
R3 on Freeview or Freesat (digital so an arbitrary
buffering/coding/decoding delay).
I presume TV sound is thought to be "good enough" (*) that there is no
longer a need to simulcast on radio to get a higher quality of sound.
Was simulcasting done after NICAM TV sound had been introduced, or was
NICAM thought to be a significant improvement over mono FM sound so simulcasting was no longer necessary. What was the typical delay between
FM and NICAM sound on the same channel - how "nearly instantaneous" was
it? When I tried with a TV on FM sound and another using NICAM sound, I wasn't aware of any delay of one wrt the other, so it was pretty damn good.
In 1988 I bought a non-NICAM VCR with simulcast recording capability.
Then in 1990 or 1991 I bought a NICAM VCR which also allowed simulcast recording. Perhaps NICAM wasn't available from all transmitters.
Both VCRs allowed recording of sound from an external source, with or
without the picture.

As far as I can recall, simulcasting was only done with TV broadcasts
that were thought to benefit from stereo sound, typically the Proms.
The quality of the FM sound channel for a normal TV transmission could
be very good, but it was only in mono.

I'm surprised more VHS VCRs didn't offer the ability to record video
from the built-in tuner and sound from an external source such as a
radio, for simulcasts.

So if you just listened to the TV sound, you would get either left or
right. And vice-versa for the radio sound.
Must have been weird for those who didn't have the capability to rig
up the appropriate stereo setup, which would've been mostly everybody.
I wonder how this got past the common-sense filter of the time.
That's not how it worked at all. TV sound was FM mono. Radio sound was
FM stereo. For a simulcast the radio FM stereo was recorded onto the
"Hi-Fi audio" track (sub carriers on the video). It was also put onto
the VHS linear tracks - in mono - I don't think there was any attempt to split them for stereo, but I do have some pre-recorded tapes which claim
to have Dolby B on the linear tracks.

Another couple of questions...
Before NICAM was developed, had there been any development work done
on pilot-tone stereo, as for FM radio? Or was there insufficient
bandwidth between one UHF channel and the next to allow room for the additional L-R signal modulated on sound_carrier+38 kHz?
Did VHS recorders always use the NICAM signal (in L+R form) for the
linear (mono) soundtrack on the tape, or did they record NICAM to the
hifi track and FM sound to the linear track?

Using the TV sound/ FM mono radio for stereo was an appalling bodge.
It must have sounded crap, the two tx paths were totally unmatched in
terms of eq and phase.
Maybe TV sound and radio sound for simulcasts were deliberately fed
through
a common audio chain as far as possible between mixing desk and
transmitters, to avoid obvious mismatches. Can't do anything about
different
bandwidths and therefore different frequency responses (for AM TV
sound on
405-line TV). Presumably the matching between FM TV sound (625-line)
and FM
radio would have been much better.
Was the sound mix for TV sound and Radio 3 sound the same (apart from TV sound being an equal mix of L and R) or did radio use a different mix
of the
available microphones at the concert being broadcast?
I remember someone suggesting that the TV sound mix tended to favour whichever instrument was being shown at the time, which sounds
implausible
because it means the sound mix was constantly changing depending on which camera's shot was being used at the instant.

The BBC Third Programme transmitted its channel of the stereo pair on

From what I remember, if it was a solo, then that was, and still is,
tweaked slightly, but not in a way directly connected to the camera in
use, though the soloist would also normally be shown on screen while
they were being featured. This would not necessarily sound strange on
the radio.
And anyway, the TV amp and loudspeaker and radio amp and loudspeaker

With some television sets you were lucky if you got a proper sound
output pentode; some used a low power RF pentode, such as an EF80, as
the sound output valve. At least most radio sets didn't sink that low.
