|Band D||13.8 - 20.0 MHz|

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.
