Tom's Tech Talk #17: How to Troubleshoot Mobile Radios

WARNING: This article assumes you have an intermediate understanding of RF and two way radios.

Every so often you may experience a problem with your mobile radio, regardless of its manufacturer. I've heard one of our technicians once say “a radio is a radio; it transmits and it receives. I don’t care if it is Motorola, Johnson, Kenwood or Vertex.” It doesn't matter what type of radio you have because they all need the same basic components to work properly. Because of this, we can point out a few problems that typically occur among all mobile radios.

   In order to address a mobile radio problem you first need to know which part of the radio isn't working properly. Before we get to troubleshooting, let me define the pieces that make up a mobile two way radio:

   Does Your School Have a Secure Emergency Preparedness Plan in Place? 

   In the aftermath of 2012, educational institutions everywhere re-evaluated and re-examined their security and emergency-preparedness plans. Administrators went into crisis mode to comfort students and parents while ensuring all that plans and procedures were in place to keep their schools safe and secure. A critical piece of the plan is communicating across school grounds, and two-way radios are an instrumental part of that plan. 

     On this blog we talk a lot about mission critical situations and the communications and technology that assist first responders and public safety agencies every day. But the importance of good communication doesn’t stop there.  We realize that it's essential to keep everyone connected to their teams, everywhere they go.  We’re able to provide solutions that reach industries very diverse in nature from public safety, whether it’s helping customers in schools, casinos, hotels or sports stadiums. Take for instance our rental department, which puts radios in the hands of security crews at concerts,  videographers covering special events (like the Tour of Elk Grove) and even engineers running environmental tests on equipment at a power plant--which probably isn't the first place that comes to mind when you think of places using two way radios. Let’s take a closer look at the last scenario mentioned, since we happen to know of a nearby environmental testing firm called Mostardi Platt, that was willing to share how two way radios help their staff stay connected.

An Update from the FREQ Squad's Ann Tenna

    Have you ever thought about the antenna on the end of your radio or the ones on top of a tower or building? Probably not much. But there's a lot more to an antenna than what meets the eye. It’s not just a stick that gets installed there; it is actually a tuned circuit which becomes part of the radio (or the system) itself. This antenna circuit resonates on a specific frequency band. Antennas work to amplify coverage, making them a Very-Important-Part (VIP) of the radio system working well. And since I happen to be an expert in this area, I've put together a list of things to help you become an expert too. 

What Local Municipalities Need to Know about LTE & P25

      In a discussion I was having with one of my co-workers, I was asked about P25 (public safety's latest standard), LTE (long term evolution) and what it means to local public safety radio users. It made me think about our current radio system configurations, the abilities they have now and what is needed to get them to a higher level. Current systems used by our local governments operate analog two way radios, in essence, I talk and you listen. Similar to cellular phones in 1983, when a call was placed it was on one specific frequency. Effective, yet in our world today with ever increasing demands on information, it lends itself to being archaic. In addition with the limited frequency resources from the FCC we find adding any type of capacity to these legacy systems in a similar analog fashion is restricted by co-channel users on that frequency. Thus we are educating users on digital and what it will do for them.

Two Way Radios Ensure Safety of SnoCross Racing Officials & Racers

Great Lakes Snocross (GLX) teaches the sport of SnoXracing in a safe and positive environment and is known as the “Southern most Snocross organization” in the country. GLX is a Not for Profit organization and one big extended family with everyone helping each other with parts, repairs, and support throughout the season.  Racing occurs pretty much every weekend from January to mid-March, with practices taking place a couple evenings during the week. Chicago Communications has been supplying the organization with rental radios and equipment for the past 5 years. The radios are used on the track by all of the crew members, who also use ear muff headsets to eliminate the noise of the snowmobiles during communications.  The track crew consists of workers at designated positions around the track who start the races, watch for accidents and flag riders by waving yellow flags to slow/avoid, watch for illegal moves made by riders which may cause him/her to be disqualified, and monitor the finish line.  The radios enable the workers to talk with each other before, during, and after races, as well as communicate with on-site emergency medical staff, and the race announcer and race director in the track tower.  Essentially, they make full communication possible throughout every race event.

Top 3 Trends of Radio in 2013

With 2013 finally upon us, it is time to move forward with regard to radio. Last year lead to one of the largest years radio dealers have seen in 20 years, mainly due to the Federal Communications Commission's mandate for Narrowbanding all radio channels below 512 MHz. Narrowbanding created scheduling conflicts and made things hectic for those involved, but overall, it allowed us to revisit with all of our customers. Some abided by the mandate, took the proper steps and have completed narrowbanding. Some have not.  In addition to that, changes occurred with the D Block legislation that left the 470 MHz users on a freeze and rumors of a private LTE network for public safety left many questions unanswered as well. Looking ahead though, the future of two way radio remains to look bright, and here are 3 trends you’re sure to see this year.

The Allerton Hotel has been around since 1924, boasting many impressive credentials including its classification as a historic landmark of Chicago and its unique Northern Italian Renaissance architecture. It has a rich history of being one of the city’s most exciting social hot spots, and was originally operated as a club hotel for men. The 26 story historic building consists of 12,000 square feet of meeting and event space in addition to its 443 guest rooms, all of which is made operational by the hotels' 225 employees.

    At any given time there’s about 40 employees using portable radios across the Engineering, Security, Housekeeping, Room Service and Banquet/Event departments. In the hospitality industry, meeting guest's expectations is crucial, so timing and coordination are essential to achieving rapid response times. Communicating instantly and efficiently amongst your staff is critical to providing excellent service and customer satisfaction. Whether it’s getting a guest extra towels to the room or responding to an electrical issue on the roof, the operator stationed at the base station relays the message and dispatches the respective department to respond right away. Two way radios expedite guests’ requests in a timely manner and keep the operations running smoothly on a day-to-day basis.

Thanksgiving has grown near once again and what better way to celebrate the holiday than joining friends and family to support a good cause, right?! For the past 28 years the Dan Gibbon's Turkey Trot has strived to do just that, donating all of its proceeds to benefit organizations operating in and feeding those, in DuPage County. Last year's race hosted more than 7,600 attendees at the event, putting the predicted expectancy for this year over 8,000 people! The event has seen enormous growth each year since the 74 runners that participated in the very first 5k race.
