The September 1944 issue carried an article profiling the Signal Corps and detailing the story of how the walkie-talkie was actually developed. Not surprisingly, an unnamed ham serving in the artillery was accorded full credit. Ac- cording to the story, in 1932 he read VHF pioneer Ross Hull’s articles in QST on a midget 5 meter transceiver,3 and proceeded to develop his own for military applica- tion. His work eventually caught the eye of Signal Corps engineers, and the first military walkie-talkie—the SCR-194— was eventually developed for field use.

A walkie- talkie is a half-duplex communication device; several number of walkie talkies use a single radio channel, at a time only one radio can transmit signal on a channel, even though any number can listen. Normally the transceiver is in receive mode; when the user wants to talk he presses a ”push-to-talk” (PTT) button that turns off the receiver and turns on the transmitter. They communicate with each other using wireless frequency band. Typical walkie-talkies correspond to a cellular phone, possibly slightly larger but still a single unit, with an antenna mounted on the top of the unit. Where a phone’s earpiece is only loud enough to be heard by the user, a walkie-talkie’s built-in speaker can be heard by the user and those in the user’s immediate neighboring. Walkie-talkie transceivers may be used to communicate between each other, or to vehicle-mounted or base stations. In our system we increases the communication distance between two devices.

WHAT IS GMRS? For readers who may not be familiar with GMRS, the following is provided. A. GMRS originated in the era following the end of World War II. Prior to that time use of what is now referred to as “Land Mobile (2-way) Radio” was quite limited to just a few public safety and special industrial uses. With the advances of higher and higher frequency abilities developed during wartime, substantial new opportunities for eXpanded use of “Land Mobile” radio presented. At the suggestion of electronics inventor Al Gross, of Cleveland, the Commission created a new radio service, the “Citizens’ Radiocommunication Service” in a new Part 19 of its Rules, in 1947. The entire 460 – 470 MHz band was allocated to CRS and eligibility was designed to provide land mobile 2-way service to all entities that hereto- fore were not eligible, including businesses and individual people. Remember, this was 11 years before the Business Radio Service was created by the Commission in 1958. B. The Commission soon realized that UHF technology was far from readily available to individuals at consumer prices, and provided for relaxed technical rules for more MD Docket 20-270. Comments by P.

    Irving Al Gross - W8PAL - *1918-2000* It didn’t take long until we knew there was someone special here. So much so that our subjects papers and archives are housed in collections exhibit Torgerson Hall, Virginia Tech Univ Blacksburg Va. Inventor, engineer businessman, Mr. Gross born in Toronto and was raised in Cleveland Ohio. He discovered his lifelong enthusiasm for radio on a steamboat trip on Lake Erie at age 9. The ships radio operator let him listen to the wireless and the crackling noises of the telegraph signals. Inventor Al Gross was forever hooked! By age 12, Gross had turned his parents basement into a radio laboratory, with equipment patched together from junkyards. At age 16, he obtained his amateur radio license 8PAL. Gross entered the BSEE program at Cleveland’s Case School of Applied Sciences in 1936. Determined to exploit the unexplored frequencies above 100 MHZ, Mr Gross set about inventing a mobile, lightweight, hand-held two-way radio - Then in just two years, Gross had accomplished the invention and patented the Walkie-Talkie in 1938. Al’s top secret system for the OSS (CIA) was not declassified until 1976, the U.S. Joints of Chiefs have called the talkie, one of the most successful wireless intelligence gathering methods ever employed. After the war, the FCC became aware of Gross’ work. They allocated the first channels for personal radio service in the Citizens Radio Service.
