    A Brief History of Ham Radio

    From 1900 to 1912 Americans experimened with wireless radio without any regulation by the government.

    In 1912 the Wireless Regulation known as the Radio Act was passed, and it limited amateurs to the 200 meter band, only. Since this band is just about unusable, interest dropped in wireless radio.

    Because the 200 meter band was limited to only about 35 miles this prompted Hiram Percy Maxim (W1AW) in 1914 to organize the American Radio Relay League (ARRL) in order to help relay messages from coast to coast.

    In 1924 Amateurs were assigned new Ham bands
    80, 40, 20, and 5 meters.
    In 1927 Congress passed the first laws regulating radio transmissions system by creating the Federal Radio Commission, the precursor agency to the FCC and Amateur is used for the first time as a Federal Statute.

    In 1928 the first official ARRL HQ station went on the air from Hartford as W1MK. Then in 1936 Hiram Maxim passed away, and in the same time period the Hartford station was distroyed by flood.

    Construction of a new Headquarters building was begun in Newington and completed in 1938. At that time the FCC assigned Maxim's famous call sign, W1AW, to the ARRL station as the first-ever memoriam call sign. Formal dedication took place in September 1938 on Maxim's birthday.

    In 1934 The Communications Act created the Federal Communications Commission. Amateur Licenses were Class A, Class B, and Class C.

    In 1951 the FCC reorganizes the amateur licensing system. The Class A, B, and C Licenses were replaced by the Advanced, General, and Conditional. Also new license classes were created, Amateur Extra, Novice and Technician.

    Beginning in the year 2000....
    The FCC issues six license classes, each authorizing varying levels of privileges. The class for which each licensee is qualified is determined by the degree of skill and knowledge in operating a station that the licensee demonstrates during an examination to Volunteer Examiners (VE) in his or her community.

    Operator class license classes are:
    Technician, General, Amateur Extra

    Grandfathered Operator Classes:
    Novice, Technician Plus, Advanced

    Field Day

    VVARA Club members operate in less than optimal conditions on Field Day. A premium is placed on developing skills to meet the challenges of emergency preparedness as well as to acquaint the general public with the capabilities of
    Amateur Radio.

  • EchoLink


    It is software which allows Amateur Radio stations to communicate with one another over the Internet, using voice-over-IP (VoIP) technology. The program allows worldwide connections to be made between stations, from computer to repeater and link stations,
    or from computer to computer.
    There are more than 38,000 registered users worldwide!

    For more information



    Internet Radio Linking Project


    The IRLP uses Voice-Over-IP (VoIP) custom software and hardware. Coupled with the power of the Internet, IRLP will link your radio site to the world.

    IRLP operates a network of dedicated servers and nodes offering very stable worldwide voice communications.

    A note from Joe Ruby - KC7GHT
    Hi,
    I really enjoyed browsing your VVARA web site
    www.vvara.org
    It contains a lot of very useful information.

    I wanted to correct an error that I found. I believe your web page link to my IRLP web site is incorrect.
    As it should be:
    http://sky.prohosting.com/wb7crk/sarc/irlp.shtml

    Also my node number is 3820, instead of 382. We went to 4 digit node numbers about a year ago.
    There are now over 1252 IRLP nodes world wide. Each one of these nodes is a amateur radio station.
    I hope to see you at your meeting this Fall. I always enjoy visiting with you guys.

    Amateur Radio on the International Space Station
    (ARISS)

    You may communicate with the crew using voice, packet (computer) radio or television. It all depends on what equipment the crew has in space.

    Frequencies used for ARISS Call Sign is NA1SS
    Voice Downlink: 145.80 (Worldwide)
    Voice Uplink: 144.49 (Regions 2 & 3) 145.20 (Region 1)
    Packet Uplink: 145.99 (Worldwide)

    A typical ARISS ground station includes a 2-meter FM transceiver and 25-100 watts of output power. A circularly polarized crossed-Yagi antenna capable of being pointed in both azimuth (N-S-E-W) and elevation (degrees above the horizon) is desirable. But successful contacts have even been made with verticals and ground plane antennas. Commercial and public domain software is available to help track when a shuttle or the ISS will be in range of your station, and where to point your antenna. For more details on assembling your station, you can buy a Satellite Handbook from ARRL.

    OSCAR - Orbiting Satellite Carrying Amateur Radio.

    For years, Amateur Radio operators have been using satellites to communicate over long distances, satisfying not only their passion for communication
    but also their interest in technical experimentation.

    More than a dozen amateur satellites remain in orbit today.

    "The successful launch of OSCAR 40 denotes the start of a new era in Amateur Radio," says Robin Haighton, president of The Radio Amateur Satellite Corporation (AMSAT). AMSAT is an international group of volunteer radio enthusiasts who share an interest in building, launching and communicating with each other via Amateur Radio satellites. "Once more, Amateur radio operators will be at the leading edge of experimentation in communications," says Haighton.

    The term "OSCAR" stands for Orbiting Satellite Carrying Amateur Radio. This satellite is the 40th in the OSCAR series, with began with the launch of
    the first U.S. amateur satellite in 1961.

    Amateur TV

    Transmit and receive live action color AM TV in the 420-450 MHz Amateur band with the TC70-20S 20 Watt all in one box 70cm ATV Transceiver unit to other hams.

    Any FCC Licensed Technician Class or higher Amateur Radio operator can transmit and receive live action color video and sound to other hams that looks and sounds just like commercial broadcast TV with our time proven equipment. Hams should be seen as well as heard.

    Televise live or from tape your ham radio club meetings to those who could not make it in person.

    o Show critical locations to local emergency service groups or back to the EOC during ARES & RACES drills or actual disasters, parades or races, etc.

    o See Space Shuttle and ISS video and audio if some one is repeating it from their satellite TVRO.

    o See the edge of space from amateur balloons or rockets as high as 100,000 ft.

    o Getting a pilots view from a camera in a R/C model aircraft or real airplane, and much more.

    Slow Scan Television (SSTV)

    One of the most fascinating yet often misunderstood and neglected facets of Amateur Radio. Most people think it is poor quality black & white images using equipment costing kilobucks. That was true but it isn't anymore.

    There are basically two methods used to send pictures over ham radio. Fast Scan TV is very similar to broadcast TV: full motion color images. This requires a few megahertz of bandwidth so it is used only on UHF. A single transmission is wider than the entire 2 meter ham band.

    The other method is Slow Scan TV: still images sent through voice transceivers over a period of a few seconds to a couple minutes. Early pictures were low resolution black and white. Now nearly all images are higher resolution color.

    Microphone History

    ¹ "Sir Charles Wheatstone in 1827 was the first person to use the term "microphone." The first microphone was a telephone transmitter invented by Emile Berliner for Alexander Graham Bell in 1876. With the invention of the radio, new broadcasting microphones were created. The carbon microphone was invented in 1878 by David Edward Hughes, and later developed in the 1920s. The ribbon microphone was invented in 1942, for radio broadcasting.

    During the 1970's, dynamic and condenser mics were developed, allowing for a lower level
    sensitivity and a clearer sound."

    Telegraphy History

    ² "Telegraphy (in greek: writing in distance) is, as we know, a communication system able to transmit signals which represent coded letters, numbers and signs of writing. Telegraphy has very ancient origins, and can be divided in acoustic, optical and electrical."
