Title: Apparatus for use in radio-frequency communications systems
Inventor: DREW LESLIE ALFRED
IPC: H04B7/26
Filed: 1965-01-27
Abstract: 1,116,771. Radio signalling. MINISTER OF TECHNOLOGY. 27 Jan., 1966 [27 Jan., 1965], No. 3532/65. Heading H4L. In a radio communication system of the type in which mobile stations co-operate with a plurality of remote fixed receiver stations feeding a central station, each remote receiver includes an aerial 1, attenuator 2 shorted by a switch S1a, when a transmitter (not shown) is not transmitting, and a receiver 3 which supplies the speech signal via a combiner 6 and landline or radio link to the central station. The receiver 3 is muted when the amplitude of the received R/F signal falls below a predetermined level. The muting circuit (not shown) controls switch 52 so that a tone oscillator 4 is connected to an amplifier 5 only when the receiver is not muted, the A.G.C. circuit of the receiver 3 controlling also the amplifier 5. In this way a tone signal from the oscillator 4 is modulated by the amplifier 5, the output of the amplifier 5 being progressively reduced as the input signal to receiver 3 increases and this output signal being combined with the speech signal at 6 for transmission to the central station. At the central station a filter 7 selects the tone signal which is supplied to a detector 8, the speech signal being supplied via an amplifier 9 and combiner 10, where it is combined with the outputs of similar amplifiers, to an output amplifier 11. The output of detector 8 is applied to control the amplifier 9 so that the stronger the signal received by receiver 3 the greater the gain of amplifier 9. A channel busy relay 12 lights a lamp 15 whenever a tone signal is received, a relay being provided for each remote station, and the relays 12 controlling amplifier 11 so that when no tone signal is received the gain of amplifier 11 is reduced. When the transmitter at the remote station is operating, at approximately the same carrier frequency as the receiver, switch S1a is opened so that the received signal is attenuated. Switch S1b is closed so that the D.C. output of the tone detector 8 is compared at 16 with a reference voltage corresponding to normal operation of the transmitter, an alarm 17 being operated if the voltages differ by more than a predetermined amount. The comparator 16 may be arranged to switch in spare equipment if a fault occurs. The tone signal may be frequency-modulated by the A.G.C. signal and amplifier 5 dispensed with, or a form of p.c.m. may be used.
