Reception Set R107
The Reception Set R107 was a receiver
designed for CW and RT reception and was usually employed in conjunction
with Wireless Sets No12 and 33.
The Frequency Range was 1.2 to 17.5 Mc/s in
three overlapping bands.
Band 1 : - 17.5 to 7 Mc/s.
Band 2 : -
7.25 to 2.9 Mc/s.
Band 3 : - 3.0 to 1.2 Mc/s.
The set was
designed for operation from a 12 volt accumulator or alternatively
from 100/250 volts (50 c/s AC).
Change over from DC to AC operation was
accomplished by means of a two-way switch in the power-chassis.
The
complete apparatus comprises of three separate chassis units i.e. RF,
IF/AF and Power. |
|
These are mounted on a steel framework
and a sheet steel panel carries the receiver controls.
Connection
between the three units is achieved by means of tag-boards.
Circuit
Description
A nine valve (eight plus rectifier) super-heterodyne
circuit is employed.
The valves were indirectly heated (6.3v heaters) and
were fitted with International Octal bases.
There are four RF
pentodes (ARP34), four double-diode-triodes (AR21) and a full wave
rectifying valve (6x 5G).
The circuit was arranged as follows.
An RF
stage was coupled by means of a band-pass filter to a mixer stage with a
separate 1st Local Oscillator. |
|
The intermediate frequency signal (465
kc/s) thus produced was amplified by two IF stages which were followed by
the combined signal detector AVC and AF stage.
An
output stage and Beat Frequency Oscillator complete the circuit.
Power
Consumption
DC 3.25 amps at 11.5 volts. AC 50 volt-amps. |
