    The birth of radio astronomy

    Back in the 1930s radio communication was opening up the world. For the
    first time it was becoming technically possible for a person in any country
    to communicate with anyone else on the planet.

    One of the companies working on this new communications frontier was Bell
    Labs, in New Jersey. To help them design the new system, they gave one of
    their engineers, Karl Jansky, the job of identifying sources of
    interference that could affect the new services. Over the following months
    he identified the radio static from thunderstorms and other natural
    phenomena, and the countless forms of manmade interference.

    Intriguingly, he found that when this interference was absent, he could
    hear a steady hiss, which went away if he disconnected the antenna. He
    scanned with the antenna and found the direction in which the hiss was strongest, and found, to his surprise that during the day the interference
    peak moved from east to west. After months of work he concluded the culprit
    was the Milky Way, with the strongest signals coming from the direction of
    the constellation Sagittarius. Jansky had discovered cosmic radio waves,
    that the Milky Way is a radio source, and the strongest emissions come from
    the direction of the centre of our galaxy.

    HAM radio still has a role in our modern age

    TOLEDO, Ohio (WTVG) When severe weather is in the forecast, a sometimes-forgotten group of people tune in to help relay important information. The technology behind HAM radios is about 130 years old, but
    the simplicity of that form of communication makes it very durable, and a reliable backup during emergencies.

    “HAM Radio is pretty much if everything else fails. No cell phones, no internet, anything like that. Amateur radio can still get out and send
    messages to whomever would need them,” explained Brenda Krukowski, a HAM radio operator with Amateur Radio Emergency Services (ARES).

    Local Amateur Radio Club preserves radio history

    Today, most people take radio for granted as they have been able to listen
    to music and news like it has always been there. However, if you could to
    go back before the turn of the century and turn on one of today’s radios,
    all you would hear would be silence and static. It was only after the turn
    of the century when you might even hear only Morse Code dits and dahls then used to communicate as voice was not yet possible.

    Recently, Highland Amateur Radio Association member Dr. David Gunderman notified the Club his father, Robert, needed to relocate to a smaller
    residence and wanted to donate his early “home-brewed” radio equipment to an organization who would not only honor those early radio pioneers but preserve the equipment he designed and built for future generations (with
    an interest in early radio history) to enjoy and appreciate.

    Thus, a different and challenging project was undertaken by the Highland
    County Club.
