TCS 12 TCS12 Transmitter 52245 Receiver
46159
The TCS series of transmitters and
receivers were designed and originally built for the US Navy by the
American Collins Company, though later several other manufactures also
built them.
The series was numbered consecutively TCS1 to TCS14. The US Navy
numbered them COL-52245 for the transmitter and
COL-46159 for the receiver.
The numbers prefixing the Navy number is a
code denoting the manufacturer, eg COL Collins CHI Hamilton.
They were supplied to the US Navy for duties
similar to the British W/S19, e.g. / P and / M from tanks, trucks
and similar vehicles.
The TCS was also used as an emergency radio aboard
merchant ships.
Although intended to work as a single inter-connected
unit, the transmitter and receiver are in fact physically
separate.
|
|
| Transmitter 52245
The
transmitter consists of a VFO / Buffer - Doubler / PA with an integral
push-pull modulator, there is provision for four switched crystals as an
alternative to the VFO.
Frequency
Coverage
1.5 to12.0 Mc/s in 3 bands.
Band 1 : - 1.5 to 3.0
Mc/s.
Band 2 : - 3.0 to 6.0 Mc/s.
Band 3 : - 6.0 to 12.0 Mc/s.
When used in conjunction with its receiver the TCS transmitter has full
"push-to-talk" or "break-in" facilities.
Power
Supply
The power requirements for the transmitter are : -
HT (1)
400 volts DC at 200 mA
HT (2) 220 volts DC at 40 mA
LT12 volts AC/DC at
2.5 amps
Relay supply 12 volts DC at 1 amp. |
|
The Transmitter runs approx 35 watts
input on phone and 80 watts on CW.
The Modulator
The TCS had an incorporated modulator, it consists of a pair of 1625's
operating in class B push-pull, modulating the PA on plate and screen via
the transformer.
There is no pre-amplifier, the 1625's being driven direct
from the microphone transformer, which is designed to work with a
carbon-button microphone of about 100 ohms.
Auto-bias and the energizing
voltage for the microphone develops across a resistor.
The "Emission
Selector" switch cuts the heater volts from the parallel PA valve
when placed in the "Voice" position, it also switches on the
heaters of the two modulator valves .
|
|
It also places the modulator valves on
the HT rail via a relay contact, though no HT will be available until
the push-to-talk switch is closed and the relay applies the HT.
When the
transmitter is switched to the CW condition, the modulator valves have
neither HT nor heater volts applied, it follows therefore that when
changing from one function to another, time must be allowed for the
heaters to warm up.
All supplies to the transmitter are fed through a
16-pin Cannon plug.
Receiver 46159
This is the companion
receiver to the transmitter mentioned above, the Frequency range is
identical.
The size, panel layout and construction are very similar to the transmitter
(52245).

The Receiver 46159 is a conventional seven valve superhet, the valve
run is as follows
RF,12SK7
Mixer, 12SA7
Osc., 12A6
1st IF, 12SK7
2nd
IF,12SK7
Det / BFO, 12SQ7
Audio, 12A6.
The IF is 455 kc/s, it will be
seen from this that the receiver has a separate oscillator valve.
On the
front panel will be found a switch marked "Oscillator Selector"
and one of four crystals can be used as an alternative to the IF
oscillator.
The crystals are ground to be 455 kc/s above the signal
frequency (it spot tunes the receiver).
Other controls on the front panel
are : -
HT on /off
BFO on /off
CW pitch
RF gain /AVC on/off
LF gain
Band-switch and the main tuning control.

When the BFO is on, the AVC is
inoperative.
The power and control circuits from the transmitter arrive
via a twelve-pin Cannon plug, Type GK-12-23.5 AC.
Though designed to work
in conjunction with the TCS transmitter(52245),
the receiver with the exception of the power
supply is self contained.
The receiver is muted during transmission by
cutting off the HT to the screens of the RF and IF valves.
A relay in the
transmitter switches the HT from the exciter to the receiver screens when
the push-to talk switch, or the CW key is open.
The relay rests in the
receive position.
Modulation
The carbon button microphone will
modulate the transmitter to about 80%. |
|
| So much for the two major units
of the TCS equipment, apart from the Rx / Tx as described, there were
several power supplies made for the series.
These are rather rare
(particularly the 230v AC mains unit). |

TCS Receiver
Faults
My TCS Receiver had been stored for years unused, I replaced the following components I think for crackling noises, it was a while ago.
C205 100pf
C218 50pf
C220 100pf
C230 500pf
C229 I reduced it to 1000pf from 2000pf something to do with the BFO pitch.
I also replaced the following resistors on the BFO just in case as it was intermittent.
R222 220k
R221 220k
R229 470k
The only modification I did was to add a 25mfd to the un-decoupled cathode of the audio output valve V207, to increase the volume.
It will now drive a speaker at good volume : )
Good Luck Allen G0RIT
