MAIN DIFFERENCES

Between

WIRELESS SET, CANADIAN, NO. 19 MK. III

And

WIRELESS SET, NO. 19 MK. III OF BRITISH

MANUFACTURE

 

Front view of, Wireless Set (Canadian) No. 19 Mark III. 

 

Canadian and British Wireless sets No. 19 MK. III are fully, mutually interchangeable in all their applications and installations. All accessories and essential spares such as microphones and headphones, control boxes, variometer, aerials, etc., are individually and mutually interchangeable. Most of the components used in the Canadian, Mk.III Set, are the same as those used in the British version. Not all of the, however, are fully, mutually interchangeable. The most important differences between the two versions are listed below:

 1.  The Canadian set includes a Frequency Adjuster not used on the British Set. The presence of this makes the main tuning condenser non-interchangeable with the British gang-condenser.

2.  The Canadian Set includes an AVC ON-OFF Switch. Such a switch is not used on the British Set and the British panel has no provisions for this Control.

3.  The British Set has a new circuit for the heterodyne oscillator, while the Canadian set uses the same system as used on the Mk. II Set. That means that all heterodyne oscillator coils and R.F. coils in the sender are non-interchangeable.

4.  The British Set uses a new type of circuit for the automatic drive control of the output stage, while the Canadian Set uses the same circuit as on the Mk. II.

5.  The British Set has a new meter transformer circuit in the Variometer, while the Canadian Set uses the same as on the Mk II.

6.  The British Set includes a resistance-capacitance network as tone-filter on CW, which is not used on the Canadian Set.

7.  The Canadian Supply Unit is entirely different from the British version and uses an entirely different dynamotor. Hardly any parts of the Supply Unit are interchangeable but the Supply Units as a whole are fully, mutually, interchangeable.

These are the main differences between the British and Canadian versions but it must be pointed out that the arrangements of components and parts on the chassis, differ quite considerably, and that maintenance spares for the Canadian Set cannot be used without careful consideration in the British model and vice versa.

The Canadian WS19 MK III is more like the MK II than the British version, using the same heterodyne oscillator-circuit, the same PA-tank circuit and drive control, and omits the British CW-audio-peak-filter.
