The BC-639A is a ground based AM VHF receiver covering the nominal frequency range of 100 -156 m/cs. The set was built for the U.S. Army Air Force in WW2 as part of a communication system to communicate with aircraft. A system of similar intent was built in Australia during WW2 by Radio Corporation of Victoria (ASTOR), with the addition of FM facilities. This system used the ARl7 receiver and ATl7 transmitter. Many of the sets had been modified after the war by the then Dept of Civil Aviation for use as monitoring receivers.This type was used at the AeradioThe BC-639A is a ground based AM VHF receiver covering the nominal frequency range of 100 -156 m/cs.

Harold Gatty was born on January 5th, 1903 in Campbell Town, Tasmania. He was a navigator and aviation pioneer. He began his career learning navigation at the age of 14 as a midshipman at the Royal Australian Naval College but withdrew after three years and became an apprenticed ship's officer with the Patrick Steamship Company of Sydney. After W. W. 1 he joined the Australian Merchant Navy where he learned the constellations while standing night watch and became an expert in celestial navigation while serving on many ships sailing between Australia and California. In 1927 he moved to California and opened a navigation school and also a laboratory repairing navigational equipment. At this time he became very interested in air navigation and was aware of the limitations of existing methods and instruments for aerial navigation. He began researching ways of improving aerial navigation. Two early inventions of his were his air sextant and a ground speed and drift indicator which formed the basis of the automatic pilot which later came to be standard equipment on most aircraft. He worked with several record breaking pilots including Ann Morrow Lindbergh (who went on to serve as a navigator for her husband Charles Lindbergh), helped Wiley Post break the world record circumnavigating the Earth, invented a new method of "dead reckoning" that revolutionised the ability to fly safely through cloudy conditions without drifting off course and famously navigated a small plane (whilst trying to cross the Pacific) over 1900 km through fog (with no radio) and using only his dead reckoning techniques, back to their starting point in Japan after they developed fuel problems. In 1932 Gatty received the Distinguished Flying Cross from President Hoover. In 1934 Gatty formed the South Seas Commercial Company with Donald Douglas with the aim to deliver air services to the islands of the South Pacific. The Company was sold to Pan Am but he continued to work for them. In 1935 he went on a sailing expedition investigating several small islands in the South Pacific and was briefly marooned on Baker Island. He was able to use his extensive knowledge of seabird habits to save the crew. He was also very interested in the ability of the Polynesians to navigate using the stars. During the Second World War Gatty was given the honorary rank of Group Captain in the Royal Australian Air Force (RAAF) and worked for the U. S. Army Air Forces (USAAF) in the South Pacific. In 1943 he moved to Washington where he developed a survival book (The Raft Book) specifically for boat crews or air crews flying over the Pacific to help them survive and navigate their life rafts in remote areas of the ocean. The original book was 152 pages long however a condensed version was made which consisted of a 64 page booklet, combined map and star chart and calendar strip enclosed in a waterproof slipcase, to be placed in life rafts for emergency use. The booklet included navigational advice and ideas such as ocean currents, estimation of distance, using a compass, measurement of angles, recognising and steering by the stars, land indications from sea birds, migration of sea birds and insects, sounds from the land, the scent of the land and ocean currents and the colour of the sea etc. After W.W.2 Gatty moved to Fiji and formed Fiji Airways (which later became Air Pacific). Harold Gatty died in August 1957.The two copies of "The Raft Book" are significant as they are a written summary of the many methods of sea navigation (both modern and historical) that existed in the 1940's. They are also a record of Harold Gatty, who played a significant role in the development of modern day aerial navigation using his understanding of different sea navigational techniques.Two rectangular brown packets with waterproof coverings (oiled paper) titled "The Raft Book" by Harold Gatty. Each packet contains a folded 64 page paper booklet with detailed instructions for navigating a small craft in open seas, a folded chart (with a map of the world and oceans, well known constellations, latitude and longitude charts, Greenwich time and a scale for string lengths and Harp scale) and a long folded paper calendar strip.Front of package - "WATERPROOFED EDITION OF/ THE RAFT BOOK / By Harold Gatty / BOOK AND WORLD CHART / FOR / EMERGENCY NAVIGATION / To open envelope tear along above line. If the envelope is used again fold the flap to keep contents dry. 1. This envelope contains a book, chart and tape for emergency navigation. The contents are folded to take up the least possible space and therefore should not be removed until needed. 2. if the chart and tape are immersed in water for a long period, there will be a slight variation in the scale but the strength and resistence to tear of the paper will not be changed. In the event of long immersion, dry the chart and tape as much as possible before using in order to in order to get the greatest accuracy in scale.
