The Wireless sender C11
Is a portable high frequency sender covering the frequency band between 2 and 16 Mc/s.
It was designed primarily for mobile operation in certain AFV installations and in command and wireless vehicles at Brigade, Division and Corps levels.
It could also be used for general purposes such as truck-ground installations etc.

Its associated receiver is Reception set R210.
Transmission systems are provided for voice (AM), hand-keyed CW telegraphy with break-in working and carrier frequency shift (CFS) operation through a CFS adapter unit.
 

With the aid of a 100 kc/s crystal calibrator built into the sender, the operator is able to set up the equipment to any required channel within the limits of the frequency coverage without recourse to netting and without radiating from the aerial.

Wireless sender C11 and its associated receiver R210 were operated in conjunction with standard vehicle control boxes and wireless control harness types 'A' and 'B', through which connections are made to the various microphones, headphones and send-receive pressel switch circuits.

The keying unit for hand-keyed CW working forms part of the type 'B' harness.
The AF amplifier incorporated in the sender can be used for intercommunication purposes in vehicle installations.
 
A separate Aerial tuning unit No 7 is provided and is connected to the sender by means of a 72-ohms coaxial cable.
The length of this cable is not critical but must not exceed 300 feet. A meter built into the aerial tuning unit enables adjustment to be made for maximum aerial current.

In vehicle installations the aerial tuning unit is connected to an Aerial base No 31, to which the rod or wire aerials are attached. Sender and DC power supply unit both contain built-in cooling systems, with air inlets on the front panels and outlets at the rear.
Aerial tuning unit No 7 is a sealed unit. The sender and the supply unit are shower proof but are not hermetically sealed.

Frequency and Range
Continuous frequency coverage from 2 Mc/s to 16 Mc/s in three ranges.

Range
1 :- 2 to 4 Mc/s
Range 2 :- 4 to 8 Mc/s
Range 3 :- 8 to 16 mc/s

Calibration scale
Range 1 :- 2.5 kc/s
Range 2 :- 2.5 kc/s
Range 3 :- 5 kc/s

On high power the sender has a voice range of approximately 25 miles over average terrain.
This figure is based on moving vehicles using 8ft rod aerials and should hold good for any frequency channel and any time of the day or night.
It should be
increased considerably when vehicles are well sited and connected to more efficient aerials.

Distances of approximately twice the voice range should be obtained when CW is used.
A switch on the front panel enables the sender to be operated on either low or high power, the ground range on low power being one half of that on high power. Low power should be used when full range is not required.

Construction:-
The equipment was suitable for installation in wheeled and tracked vehicles and in ground stations and for use  and storage anywhere in the world.
It could be parachute dropped in standard containers, carried by mule pack, or man handled.
The units are finished in Drab Olive.

I used this manual to renovate my C11

The quality of the manuals we sell is normally 100 % the original copy of the C11 R210 manual is not quite 100%

It is however the best I have seen and I have used it to fully renovate my C11 R210 with out any problems at all. 

All the text pages are fine, 95% of the component values on the diagrams are fine.

A very small number are difficult to read, it is otherwise a very good manual. 

We offer a full refund including post if you should disagree with this description.
