The 300 Se handheld radio was the first oscillating hand-held radio marketed by Crawford in 1929. It was made in various versions with large and small antennas, for example the 8833A, which used a very large "Binocular" antenna. The 300 Se is one of the most important radios ever made, because it was also one of the first amateur radios that could be operated without a license. It required no batteries for operation, and it tuned itself automatically at 500 meters or 1/2 mile. This feature helped set it apart from other ham radios that were then available on the market. The 300 Se was made to be compact and light. It was built in 7"x6" size, which makes it even more unique today. The radio only weighs about 6 ounces, and it uses two AA batteries to operate. It can easily be carried in one hand or worn around the neck while still being able to receive short wave signals. Around 1930 the 300 Se replaced the 200/210 sets sold by Crawford for years, but it wasn't until 1937 when they replaced them themselves. The last antenna used with the 300 Se was the "Binocular" antenna advertised on its packaging, which is no longer manufactured since 1963. The 300 Se could be sold by itself or with one of many accessories, including the "Binocular" antenna, the "Tall Club" antenna, the "Planetary" antenna, the "Tuck-It-In-Your-Pockets" case, and other accessories. The 300 Se's instruction manual is well known in ham radio circles. It was written in 1930 by John K. Crawford III who also was responsible for its overall design. The manual describes in detail how to set it up to receive short wave signals in its simple but effective system of using a hand magnet to attract a small pitch arm that then rotated tuning coil about which it would tune the short wave band when moved by hand. The manual also provides a three-part test to make sure the radio is set up properly, and to determine its settings if any programming is needed. The 300 Se was designed in the forefront of technology at the time it was manufactured, and it has been widely imitated by amateur radio manufacturers (and even non-ham versions) since then. It's well known because of how well described and described in detail when compared to other early amateur radios that were mass-produced. Another interesting history note: In 1932, when the 200/210 sets were discontinued, Crawford had them manufactured for Sears department stores. They are still available today as "Crawford 200/210" sets on EBay or on Yahoo Auction. They are very rare and wanted by collectors.HAVE A BINOCULAR ANTENNA?
