    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.

    How to Use RoIP in Commercial Communication

    "Hey boss, I tried to call Jimmy on the radio but he didn't respond. I called him on his cell phone and he said he didn't get the radio call. Can you fix our radios to help us talk when we need to?"


    Little Construction Guy on RadioHow can the boss help out Jimmy, Frank and the rest of the radio users communicate when necessary? The solution is as simple as RoIP (Radio over IP). 
    "Frank, I'll see what I can do to help you and Jimmy communicate. Do you know anything about this RoIP communication deal?"

    What is RoIP? In our past blog, Radio over IP - What is it?, we defined Radio over Internet Protocol (RoIP) as a two-way communication method which involves trans-reception of radio communication signals over internet protocol (IP).

    Ohio Hospital uses BridgeCom Systems to link LTR Communication System

    In a critical situation communication is key. This is especially true in a hospital where lives are on the line. In one Ohio hospital system they face a greater challenge. How can several of the hospital buildings, spread out over a distance, communicate like they are one? 

    The Requirement: Create a seamless communication network so the hospitals can communicate together using the existing LTR communication system over four three channel sites.

    BridgeCom TL-NET Hospital SolutionThe Solution: Deploy BridgeCom Systems TL-NET multi-site networking communication system. The hospitals have four LTR sites with three channels each. The main site will use a TL-NET Gateway, connected to three TL-NET Controllers. Then the controllers will be connected to their existing repeaters, and finally to the internet. The three other sites will use a TL-NET MV-2 and TL-NET MV-1 connected to three BridgeCom BCR Repeaters. What do all the pieces do and how do

    HAM-RADIO "TALKING POINTS" by Myron A. Calhoun, W0PBV

    HAM-RADIO "TALKING POINTS":

    1) Because it's shorter, we usually say "HAM" instead of "amateur radio". No one actually knows where the word "HAM" came from, but some of us think it might stand for "Hardly Any Money"!-)

    2) Speaking of MONEY, it costs CONSIDERABLY LESS to be a HAM than it does to have a cellphone:

    * HAM-license study materials are available on the Internet

    * It costs about $15 to take the test

    * It costs less than $30 for a dual-band VHF/UHF "handi-talkie" radio from Amazon.com or eBay.com

    * On the other hand, if you have gobs of money, you can spend it in HAM radio ... just as you can spend gobs of money on other hobbies (fancy cars/boats/airplanes, golf clubs, horses, home-entertainment systems, giant-screen TV's, ....) [FWIW, while I have owned and still own more-expensive radios, I paid $200 in 1975 (about $800 in today's inflated greenies) for my favorite HAM rig, a Ten-Tec Triton IV (aka Model 540) which is still going strong!]
