    What is: Data Radio and Telemetry?

    Radio

    Radio technology – traditionally understood as the wireless broadcasting of audio signals like music and speech – has had a fresh lease of life in recent years.

    In simple terms, radio technology leverages the electromagnetic radiations (EMR), which can be oscillate at desired frequency and allow trans-reception of data when attuned to the correct value. EMR waves travel at the speed of light, through any media (or even vacuum!), and may be used for either near-field or far-field communication based on the frequency specifications. In short, radio waves are just low-frequency versions of what we call “light”. Range of these EMR wave frequencies comprise a particular ‘channel’, which is precisely what the radio stations adhere to.

    Commercially, the need for transmitting information over geographical distances has skyrocketed in recent years, as has the demand for radio to meet those needs. From radar, sonar, GPS navigation systems, wireless networking, and cellular data plans at industrial scale to Bluetooth technology and near-field communication (NFC) for your hand-held devices, radio is omnipresent.

    The Amateur Amateur: 220

    The Amateur Amateur: 220

    By Gary Ross Hoffman, KB0H

    BridgeCom Systems BCR-220 Repeater

    BridgeCom BCR-220 1.25m (220 MHz) Repeater

    My friend Chuck, N0EIS, tells jokes that are either so corny that I can't believe he has the nerve to say them aloud, or so profound that I'm overwhelmed by his wit and wisdom. He oscillates between lunatic and genius, and much of the time I have no idea what he's talking about. Therefore, whenever he brings up a subject that I actually understand, I pay close attention.

    That's how I became interested in the 1.25 meter band (220 MHz). Chuck is always lauding its attributes. He tells me that it works well in the lumps and bumps that constitute the terrain of St. Louis County. Of course, Chuck can get anything to work, whereas I can get just about nothing to work, but I thought I'd give the band a try anyway.

    This was several years ago, so as you might imagine, I didn't find much in the way of 1.25m equipment on the market. Ideally, I wanted something like I already had, except with the extra band.
