Thursday January 17 meeting

Hi Everyone:
The meeting tonight is in Tsawwassen. Not too much on the agenda tonight. Keep in mind that for those who haven’t paid dues they are now payable. The AGM meeting is scheduled for late February. All positions (president, vice president, secretary treasurer and directors) are open. Were always looking for new blood to lead the club. If interested let it be known that you are interested. We are still looking for someone who can help out with the planning of the burger and brew fund raising event in April. We use the money gained from this event to help pay for the insurances and therefore keep the annual dues low. If you can spare some time and help out, we really need your assistance.

Have a friend who wants to get into amateur radio? April 2 is the start of the Basic Amateur Radio course. All the details on the website www.deltaamateurradio.com and look for courses at the top of the page.

VE7ZZV sent me an email you could find interesting.

See you tonight
Gord

I have somewhere a document outlining a number of projects by the Canadian Army during WW 2 such as the WS 19, 52, 58 and 88.

It seems that the plan was to re-equip the infantry with the 58 set, but this was delayed as the entire capacity of primary battery producers in the US, UK and Canada was already full. Producing the battery for the 58 set was shelved, and soon thereafter the war ended. The 58 set continued in use in Canada. Army Cadet units used them but I have not found reference to anybody else using them.

The same fate was met by the 29 set. The British Army had ordered 10,000 of these radios but cancelled the order in early 1945 as the war was about to end. Eventually 300 were produced for the Canadian Army which used them mostly for arctic operations where the 19 seset power supply tended to freeze up! The 29 set project continued at the Canadian Signal Research and Development Establishment up into the early 1950s when it was decided to adopt the American VRC-12 family of radios. This project also came to a screeching halt due to design and production delays and the British C42 family of radios were adopted by Canada as a stop-gap until a proper completely solid state combat radio showed up. This plan also fell apart when the Canadian Army adopted the American M113 APCS, and it was decided to purchase the VRC-12 family after all as this would allow us to use the American installation kits!

Credit was given in most records to Americans, but in truth his unit was a true portable. His story is at http://dlhings.ca/index.html and has an interesting bit about his role during WW2. As a ham I discovered I now have his callsign VE7BH There are some pictures of it on the site.

Very interesting. Pity, the photos are not better. Henk

History of the Walkie Talkie: A walkie-talkie is a hand-held portable, bi-directional radio transceiver. The first walkie-talkies were developed for military use. Major characteristics include a half-duplex channel (only one radio transmits at a time, though any number can listen) and a push-to-talk switch that starts transmission. The typical physical format looks somewhat like a telephone handset, possibly slightly larger but still a single unit, with an antenna sticking out of the top. 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 his immediate vicinity.The first radio receiver/transmitter to be nick-named “Walkie-Talkie” was the backpacked Motorola SCR-300, created by an engineering team in 1940 at the Galvin Manufacturing Company (fore-runner of Motorola). The team consisted of Dan Noble, who conceived of the design using FM technology, Henryk Magnuski who was the principal RF engineer, Marion Bond, Lloyd Morris, and Bill Vogel. Motorola also produced the hand-held AM SCR-536 radio during the war, and it was called the “Handie-Talkie” (HT).Donald L. Hings also worked on the early technology behind the walkie-talkie between 1934 and 1941, and is sometimes said to actually have invented it. Hand-held transceivers became valuable communication tools for police, emergency services, and industrial and commercial users, using frequencies assigned for these services. Walkie-talkies are also popular with some amateur radio operators, operating with an amateur radio license in several different frequency bands.Since even a powerful commercial walkie-talkie is limited to a few watts of power output and a small antenna (the physical size of the package limits both battery capacity and antenna size), hand-held communication range is typically quite short, with a typical range not exceeding the line-of-sight distance
to the horizon in open areas, and much less in built-up areas, within buildings, or underground. Many radio services permit the use of a repeater which is located at some high point within the desired coverage area. The repeater listens on one frequency and retransmits on another, so that reliable hand-held to hand-held unit range can be extended to a few score miles (kilometers) or further, using repeaters linked together.Low-power versions, exempt from licence requirements, are also popular children’s toys. Prior to the change of CB radio from licensed to un-licensed status, the typical toy walkie-talkie available in retail stores in North America was limited to 100 milliwatts of power on transmit and the 27 MHz citizens’ band channels using AM amplitude modulation only. Later toy walkie-talkies operated in the 49 MHz band, some with FM (frequency modulation), shared with cordless phones and baby monitors. The lowest cost devices are very crude electronically, may employ superregenerative receivers, and may lack even a volume control, but they may have elaborate packaging. Unlike more costly units,low-cost toy walkie-talkies may not have separate microphones and speakers; the receiver’s speaker typically doubles as a microphone while in transmit mode.The personal walkie-talkie has now become popular again with the new U.S. Family Radio Service and similar unlicensed services in other countries. While FRS walkie-talkies are also sometimes used as toys because mass-production makes them low cost, they have proper superheterodyne receivers and are a useful communication tool for both business and personal use. Operation in the Family Radio Service is restricted to walkie talkies limited to 500 milliwatts of effective RF power. Some FRS models also include the surrounding GMRS channels, which require a license.TriviaHandie Talkie refers to Mototorla portable products only. According to the US
Patent and Trademark Office, Handie Talkie became a trademark of Motorola, Inc. on May 22, 1951. The application was filed June 24, 1948 and the trademark registration number is 71560123.The abbreviation HT is commonly used to refer to portable handheld ham radios (from any manufacturer) in the UHF and VHF ranges.A walkie-talkie is called “talkie-walkie” in French._._,___
