General Description

Reception Set No 4 was built by Philips in Australia during WW2. The set was designed for interception reception and general communication, either fixed or mobile, over the frequency range 1.2 - 20.0 MHz.

The set contains 6 valves in a superheterodyne circuit. The power supply and receiver are contained in one case. There are both DC (6 volt) and AC (110/220/240/260) supplies fitted. Current consumption on DC is 4.5A and 35 watts on 240v AC.

Technical Data

The valve line up is as follows:

6U7RF Amp
6J8Frequency changer
6G8IF Amp/2nd Det/AVC
6J81st AF Amp/BFO
6G82nd AF Amp

The wavebands are:

Band A1.2 - 3.3 MHz
Band B3.3 - 8.2 MHz
Band C 8.2 - 13.8 MHz
Band D13.8 - 20.0 MHz

The IF frequency is 455kHz

Provision is made for connecting 2 pairs of headphones DLR and a 600 ohm telephone line. A small permanent magnet speaker was often used in conjunction with the receiver. This was fed from one of the phone jacks.

The set used a very solid chassis construction and was very heavy for its physical size. (41lbs, appx 19 kg)

The formation of the chassis is not unlike that used with German and Japanese radio equipment of that era.

The dial and masking arrangement is very similar to that of US manufactured receivers of the time. (example BC348)

The Reception Set No 4 is very different from other Australian manufactured sets of the time.
