Where
it

with
different

separa-
tions,
the
following
description
will
employ
corn-

band.
Thus,
the
CQM611,
CQM612, CQM613,
and
CQM614
2-metre

telephones
will
be
covered
under
the

can
be
operated
from
12-

can
be

vided.
For

Construction
The
transmitter
/receiver
equipment
is
housed
in
a
die-cast
cabinet
which
is
both
dust-proof
and
splash-
proof.
The
lid
and
bottom
of
the
ca-
binet
are
heavily
fluted
so
that
they
can
carry
a
maximum
of
heat
away
from
the
equipment.
Inside,
the
cabinet
is
divided
into
three
compartments;
these
accomodate
the
transmitter.
receiver,
and
power
supply
sections.
The
transmitter
section
becomes
accessible
on
removal
of
the
lid
of
the
cabinet
whilst
removal
of
the
bottom
plate
per-
mits
direct
access
to
the
receiver
section
and
the
power
supply
section.
A
multiwire
connecter
on
the
cabinet
provides
connection
for
multiwire
cable
and
battery
cable,
and
a
voltage
switch
on
the
side
of
the
cabinet
permits
switching
between
battery
voltages
of
12
and
24
volts.
Furthermore
the
cabinet
of
simplex
operated
ra-
diotelephones
has
an
antenna
connecter
whereas
the
duplex
versions
have
two
antenna
connectors
which
provide
connections
for
both
receiver
and
transmitter
antennas
or
a
bran
ching
filter.
