The battery powered set, which dates from the second half of the twentieth century, comprises two main components, the electronic keyer with a single lever for tapping, and a transmitter (?), both connected by a keying cable. Morse code was invented in the 1830s by American, Samuel Finely Breese by using electrical signals to quickly transmit information over a long range. In the early 1890s Italian inventor, Guglielmo Marconi improved the technology to the point where it became an essential device used for commercial and government purposes. The first practical applications were demonstrated with maritime messaging, where this simple mode of communication was seen as a timely replacement for the historic practice of signaling by flags, lights and foghorns. Cape Schanck has an earlier Morse code key, which is original to the lightstation (CSLS 0035), and Cape Otway has another early example although its provenance to the lightstation has not been formally verified (COLS 0074). The Morse code set has first level contributory significance for its historical value as an earlier communications device that has since been made redundant by more sophisticated technologies.Morse code key set. Comprised of the tapping component and a metal box part with a white electrical cord.Yes

This portable, hand held visual signaling lamp, with trigger mechanism and inner reflective disk, was used for optical communication via Morse code, with the concave mirror tilted to focus the light into pulse signals. Larger versions of these lamps are fixed on ships or pedestals and have shutters in front of the light that are opened and closed to transmit signals. Smaller hand held versions like the Cape Nelson example have a concave mirror that is tilted to focus the light into pulse signals, and despite their size the lamps were renowned for their brilliant light. Invented by Arthur C W Aldis (1878‐1953) and pioneered by the British navy in the late nineteenth century, they continue to be used to the present day. Details on the Cape Nelson lamp include a serial number, a date of 1960 and the initials of the Department of Transport, which at that time incorporated the Commonwealth Lighthouse Service. Another lamp of the same date which is held at Wilsons Promontory was provided to the lighthouse by the Department of Shipping for signaling ships but was also used for communicating with Cliffy Island, 18 nautical miles away. Point Hicks also has an Aldis lamp and an associated case, which is painted an army green colour. A fourth lamp and case formerly at Cape Schanck disappeared from the collection sometime between 1995 and 2003. These types of lamps are not rare in museum collections.These types of lamps are not rare in museum collections however the Cape Nelson example has a reliable provenance to the lightstation and has first level contributory significance as a fine example of the Aldis lamps that were distributed to lightstations throughout Victoria and Australia.This object is comprised of a black metal encased Aldis lamp with electrical cord and associated wooden carrying case with metal clasp and red leather hand grip. yes

Used to measure wind speed at Gabo Island. Max gust register and wind speed indicator were interconnected to anemometor also on display. Registor and speed / direction indicator redundant due to transition to radio transmitter and computer data recorder. This instrument for measuring wind speed by knots was made by Paton Electrical, Sydney, a radio receiving manufacturing firm which operated until c.1956. It was used in conjunction with the manual anemometer. An instrument now redundant to modern weather forecasting, it is a good example of its kind and has first level contributory significance for its historic value and provenance to the lightstation. It is a good example of its kind and has first level contributory significance for its historic value and provenance to the lightstation.Knots wind speed indicator. Housed in a black & grey metal box shaped enclosure. The front is sloped with a guage and indcator dial. Around this are eight clear orange plastic knobs with directions inscribed next to each knob.Around front in clockwise direction,"N/360, NE/45, 90/E, 135/SE, 180/S, SW/225, W/270, NW/315" On dial, 0 - 70's in 10's, "KNOTS WIND SPEED / STOCK No 6660' - 66-118-7294 / PATON ELECTRICAL SYDNEY"

This object is believed to be associated with training at the Parkville Secondary Teaching College during the 20th Century.Related to objects 450 and 452This rectangular wooden resistance decade box features four large dials for controlling resistances. The dials are mounted atop a black plastic panel, each with a square base. Three smaller dials are mounted to the right of the large dials.Embossed plaque at front: 'J. L.
