A.M.II TUNER
LTHOUGH a VHF-FM service provides the highest
possible quality of broadcast reproduction such
transmiSsions are not available to all listeners. In
addition the reception range is limited to a maximum
of 50-100 miles from the transmitter.
For areas where there is no VHF-FM service, or
where reception over greater distances is required,
the complementary A.M. service must be used.
Broadcast A.M. tuners may be divided into two
groups according to their function; those intended for
the high quality reproduction of programmes from a
nearby transmitter, and those intended for acceptable
reception of more distant transmitters.
The QUAD A.M.It tuner has been designed to
perform either of these functions, the choice being
that of the listener.
DESCRIPTION
A superheterodyne circuit is used with a tuned
Radio Frequency amplifier stage. The Intermediate
Frequency amplifier can be switched to provide either
a narrow-band response or a wide-band response.
With the selectivity switch in the Wide position
the LE amplifier allows an overall response to over
Iokc/s and the RF. amplifier ensures a very low level
of receiver background noise. When reception condi-
tions are suitable the quality of reproduction is com-
parable with that provided by a VHF-FM service.
In the Filter position of the selectivity switch
the wide-band I.F. response remains available, but a
rejection filter is included to eliminate the high pitched
whistle generated by interaction of the received
carrier and an adjacent channel carrier. The filter
rejection is so narrow that it has little effect upon the
quality of reproduction.
In the Narrow position of the selectivity switch
