Radio and Electronics Today

A—Designed to send and receive radio messages in trucks, taxis, fire trucks, police cars and civil-defense passenger cars, this lightweight unit can be installed quickly by plugging it into a cigarette-lighter outlet to obtain the necessary six volts for operation. It is available in either a variable or fixed-frequency model and may be operated on various wavelengths. It has a power output of about four watts and -a range of approximately 20 miles. It also may be used on a standard 115-volt 60-cycle a.c. line

B—A truly automatic tape recorder is now available in a compact portable carrying case. The one shown is 12 x 14 x 7 in. and weighs less than 20 pounds. It uses five or seven-inch reels and is available in two speeds. Push-button operated, there are no clutches to cause trouble. Records from microphone, external radio or other external source. The tape may be erased and re-used indefinitely. There is a neon recording-volume indicator and a jack for an external speaker. High-fidelity reproduction is claimed

C—The three folding chairs used by these television viewers are designed primarily for this purpose. They are highly versatile, however, and very useful in small apartments where space is at a premium. They fold together into a 12-in. hassock or they may be used to form a cocktail table. The folding units have iron-braced legs and stand 17-1/2 in. high when opened. The top of each unit measures 14 x 19 in. They are upholstered in attractive vinyl-coated plastic that is water and sun-resistant

D—One of the lightest and most compact hand radio transmitter-receivers ever made recently has been developed by the Raytheon laboratories. It employs tiny subminiature tubes and has a complete transmitter, receiver, battery-power source and antenna in one package. Photo D-1 shows it immersed in a tank of water in a submersion test. D-2 illustrates its method of operation. Designed to link front-line troops with other units, it weighs only 6-1/2 pounds

    Even though the trend is towards ever smaller cell phones, I wouldn’t mind one in that field phone case (D-2). At least it would be easy to find and it could have a full size number pad, or what the heck, while I’m dreaming, it could have a real dial on it!!

    Neil, if you do a lot of texting you could almost have a fullsize QWERTY keyboard on your dream phone :)
