Under a new set of rules, holders
of commercial radio op licenses of any
class, except aircraft radiotelephoneoperator
authorizations or temporary
limited radiotelegraph second -class
licenses, may be employed to stand
regular watches and perform .limited
duties on all AM stations with operating
power of 10 kilowatts or less
when employing non -directional antennas,
and at all FM stations using
10 kilowatts or less.
ONE OF THE MOST ELABORATE
BROADCASTING and television -
coverage plans ever conceived will be
employed during the Coronation of
Queen Elizabeth in Great Britain in
June.
Over 400 sound and TV circuits will
be used, and 800 extensions for microphones,
cue -lights, and headphones
will be available. At least 17 cameras
will be lined up at strategic points to
assure maximum video pickup. Not
only will there be live TV broadcasts,
but film recordings will be made, and
transmitted during the evening. Special
films will also be made for our
TV stations and flown over. Originally
a transatlantic net was to have
been used for live showing, but the
expense and involved technical problems
made it necessary to shelve the
plan.
The BBC and its foreign services
will broadcast accounts of the ceremony
in 40 different languages: Danish,
Norwegian, Finnish, Swedish,
Dutch, French, German, Polish, Czech,
Slovak, Hungarian, Spanish, Portuguese,
Greek, Turkish, Albanian, Bulgarian,
Rumanian, Serbo- Croat, Slovene,
Afrikaans, Maltese, Hindi, Tamil,
Marathi, Bengali, Sinhalese, Urdu,
Arabic, Hebrew, Persian, Cantonese,
Kuoyu, Burmese, Malay, Thai,
Japanese, Indonesian, Vietnamese, and
Russian, too.
Commentators will be stationed at
80 points along the procession route.
A temporary sound control room will
be set up in Westminster. The control
position for audio transmission will
be in the Head Verger's room in Westminster
Abbey, and television pickup
will be controlled from the BBC
broadcasting center, with a main sub -
control outside the Abbey.
Two temporary TV stations will
also be set up. One will be at Pon -
top Pike and another at Belfast. The
former will share Channel 5 with
Wenvoe, and the latter will use Channel
1, sharing it with Alexandra Pal-
ace, London. For the first time in
England, horizontal polarization will
be used for transmission, as a precaution
against mutual interference by
stations sharing the same channel.
Under consideration is a TV link
across the channel, which might
make it possible for the Dutch, West
German, and Danish TV networks to
tie in with Paris for transmissions.
It appears as if the Coronation
will not only be a big show in Lon-
don, but in many parts of the world,
too
