How to Manage Background Noise with Two-Way Radio Communication

You can now use two-way radios to minimize background noise while communicating in the workplace. Today’s radios have several advanced features that will cut out excess noise in busy environments so that you can speak to your co-workers more clearly and effectively. In this article, we discuss some of those technologies.

Automatic Gain Control – An audio signal, whether whispered or yelled at full volume, will come out clearly and crisply, at a uniform volume on the receiving end. This is a convenient feature for users that have different kinds of microphones, with some directly facing their mouth and others clipped on to a lapel.

Audio Profiles – With audio profiles that are selected by the user, a person can set up their own audio profile to match their microphone volume and hearing preferences. They can also use this feature to set up different volumes for environments that have various noise levels.

Audio Feedback Suppressor – This feature uses an advanced algorithm to block feedback from radios in your immediate vicinity. This is very helpful in busy workplaces where staff must work alongside each other and occasionally communicate with different people elsewhere in the facility.

Windporting - A remote speaker microphone may have this feature, which reduces the howling sound that can be heard when trying to speak to someone in a windy location. This is very useful when communicating outdoors during severe weather conditions. It also keeps the microphone free of water, which is helpful when it’s raining.

Intelligent Audio – This feature monitors background noise and automatically adjusts the volume of the speaker, improving audibility via the microphone. With loud background noise, the speaker volume is increased, so that manual adjustments are no longer necessary.

SINC+ Noise Cancellation – With this advanced noise cancellation, background noise is permanently suppressed, effectively handling very noisy locations and providing optimal sound quality. It also maintains crisp detail in speech when moving between loud and quiet areas, automatically changing the suppression level based on background noise volume.

IMPRES Audio Accessories – These special accessories from Motorola improve audio processing in two-way radios. They have their own set of parameters that are communicated to the radio’s DSP (digital signal processor). The audio signal from the microphone is then fine-tuned, with the gain adjusted to fit the situation, such as when the person is speaking away from the microphone.

These advanced audio features can be found on various Motorola radios and accessories. For more information, contact your two-way radio experts at Tech Wholesale. We are an Authorized Motorola Dealer with the best prices and selection.

A Simple Guide to Using Walkie-Talkies at Events

Using walkie-talkies at events can help that special event run in a smooth, organized and professional manner. Whether it’s a wedding reception, an industry trade show or a rock concert, instant communication between staff members and supervisors keeps everyone well-coordinated and up-to-date with the latest essential information. Here’s how to get the most from your radios at an event.

Choosing the Best Two-Way Radios for Event Management

Is your event indoors in a large convention hall or outdoors in an open field? Yes, it makes a big difference in what kind of radio would be ideal for your environment. Indoors, UHF radios (such as the Motorola RDU4160D) are preferred, because their signal carries best around obstructions like glass, metal and concrete. Outdoors, VHF radios have the furthest range, but they don’t carry as well through buildings or even around dense forests. For both indoor and outdoor use, choose a UHF model. If you have multiple groups of employees that need to stay connected, choose a model with multiple channels. For outdoor use, look at radios that meet MIL-STD-810 (like the Motorola RMU2080), as these are designed to be used in harsh environments.

Who Should Have a Two-Way Radio?

To decide exactly which employees need a handheld radio, take a close look at your operation. For smaller groups where staff is scattered over a large distance, it makes sense for everyone to have a radio. For larger companies such as an organization running a big festival, you can outfit each department with a radio, such as the box office supervisor, security chief, event organizer, concessions manager, VIP tent coordinator, main sound engineer, maintenance crew leader, etc.

Real-Life Examples of Radios at Special Events

A convention hall is hosting a large industry meeting of robotics engineers at their facility. There are various panels being held, floor demonstrations of the latest technology, on-site food stands and an awards ceremony. Each of these requires walkie-talkies to keep the entire operation running smoothly, attending to attendees’ special needs and any emergency situations that arise. Elsewhere, there’s a music festival in progress. Concertgoers must have bags checked and tickets scanned as they enter into the gated park. Band sound checks must go off without a hitch, and VIP tents must be well-stocked with food and drinks for musicians. Security must keep an eye on the crowd, both for unruly crowd members and for anyone who needs assistance. There are also food concessions, merchandise tables and possibly other activities going on simultaneously. In both types of events, two-way radios are important tools to keep everything orderly.

Helpful Accessories for Event Two-Way Radios

Some of the most useful two-way radio accessories for events are those that allow for discreet, clear communication in a noisy environment. Take a look at headset microphones and earpieces that can be used with walkie-talkies to improve clarity in the workplace, especially when that workplace happens to include large crowds of people and sound amplification. High-capacity batteries are another accessory that can be especially helpful for an event that runs for many hours. A belt holster can be used along with a headset microphone for maximum portability and comfortable use.

Tech Wholesale carries a wide range of accessories for two-way radios at the lowest possible prices.

Keep Employees Safe with Two-Way Radios

Two-way radios for retail and other organizations will ensure safety in the workplace. That seems like a bold statement to make, but workplace safety relies on solid communication among workers and supervisors in a timely manner. There is no faster means of communicating to a large group of employees than with two-way radios. Individual phone calls take too much time, and a public address system is just that – public. For discreet, immediate messages sent to all staff members simultaneously, walkie-talkies are the smartest choice.

Here’s how two-way radios make employees safer, with specific real-life examples.

Quick, Discreet Communication in a Retail Environment

In a retail environment, many different customers come and go. Larger facilities likely have a security team, but even they can’t be everywhere in the store. In the event of a shoplifter, unruly customer or medical emergency, retail staff with two-way radios can radio for assistance at the touch of a button. Most importantly, they can contact their fellow employees discreetly without alarming other customers. This goes a long way to ensure the safety of both employees and customers.

Group Communication at a Concert or Special Event

Special events such as large outdoor concerts, festivals and school commencements can have many attendees, making security and attending to the needs of attendees quite challenging. Two-way radios let you broadcast to your entire team immediately, whether it’s to get medical help for someone who has fallen or to alert security personnel about a potential problem such as a disorderly crowd.

Instantly Accessible and Easy to Use

In addition to handheld two-way radios and walkie-talkies, Tech Wholesale sells call boxes that connect immediately to staff members with radios. These can be effectively placed in college dorm buildings, warehouse loading docks, hospital and hotel hallways and many other locations in public buildings. In the case of warehouses, they can be used to let supervisors know about a new delivery. However, many of their uses involve public safety, as in the case of an intruder at a dorm or a medical emergency in a hospital hallway. Calling police on a cell phone will likely not provide as fast of a response as letting all staff members in the area know that help is needed.

Two-Way Radios in the Workplace Enhance Security

Especially in companies such as factories where potentially dangerous equipment and chemicals are used every day, two-way radios ensure that employees are safe at all times. Not only can supervisors notify other departments of a problem or danger. They can also put out a call for help in the case of an emergency. Broadcasting a need to many co-workers at once rather than chasing down the right person (or the closest person) enables a faster response time. Security personnel, upon encountering a problem at their facility, can quickly and quietly call for backup.

Instant Wider Coverage with Radios and Repeaters

Whether it’s a security team, hospital staff, retail business or another type of organization, two-way radios offer wide coverage in any environment, even where cell phone coverage may be spotty or non-existent. Also, if you need even wider radio coverage than your current handheld devices can provide, certain radio models (such as the Motorola RDX and the Motorola CLP Series radios) can be used with a two-way radio repeater. A radio repeater takes the signals from handheld units and amplifies them, rebroadcasting at a greater wattage and a higher physical location for improved coverage.

Two-Way Radios Demystified

There are certain beliefs about two-way radios that just aren’t true. These “false beliefs” may keep an organization from making a small investment in radios that could greatly increase their business profits and improve customer satisfaction. Here are some common two-way radio misconceptions, and we’ll debunk every one of them!

Two-Way Radios Are Too Expensive

There are radios for every budget, from family-friendly Motorola Talkabout radios and sleek, sophisticated Motorola CLS radios for discreet business use to beefy, indestructible Motorola RDX business radios. Certain models, like the Talkabouts and the Motorola DLR digital radios, don’t require an FCC license to operate, making them even less expensive. Furthermore, these are one-time investments that can be used for years without any cell phone service agreement or surcharges. Also, they reliably cover any area within the range of the handheld units, as opposed to cell phones that may have spotty coverage in certain areas. Over the long-term, walkie-talkies are the cheaper option.

An FCC License is Hard to Get and Expensive

For companies using UHF or VHR radios, you will need to obtain a license to operate those radios. However, each license is good for 10 years, and they can be easily obtained online via the FCC Universal Licensing System. Also, if you have any questions or need assistance in obtaining a license, you can call us here at Tech Wholesale and we’ll help walk you through it.

If you don’t want to be bothered with getting an FCC license, there are excellent license-free options. For personal use, family use and community radios, we highly recommend the Motorola Talkabout Series. The Motorola RMM2050 is a robust business radio that operates on MURS frequencies, which is also a license-free frequency band.

Two-Way Radio Sound Quality Isn’t as Good as Phone Quality

This certainly isn’t true anymore. Walkie-talkies offer immediate sound transfer, though the optimal radios for your use will depend upon your environment and the range required. The latest digital radios, such as the Motorola DLR Series radios and Motorola DTR radios, use advanced technology for pristine, crystal clear signals that are transmitted digitally, with zero background noise.

With Two-Way Radios, You Can’t Get Extra Features

Once again, the latest digital technology offers many of the features of cell phones but without the service charges and spotty coverage. This includes group calls or individual calling, text messaging, GPS, caller ID, call forwarding, long battery life, remote monitoring, daily alarms and more. In addition, many of the digital models meet strict military specifications for durability and toughness in extreme environments.

The Coverage of a Two-Way Radio Isn’t Good Enough

Many walkie-talkie models, such as the Motorola CLP Series and Motorola RDX radios, can be used with a two-way radio repeater, which can be used to greatly expand the range of the handheld radios. Multiple repeaters can be used to cover an entire city. The internet can be used to connect sites around the country.

Only Large Organizations Use Two-Way Radios

This is definitely one of the biggest radio myths. These days, you’ll find walkie-talkies in use at small cafes and restaurants, by friends on a skiing holiday and by community watchdog groups. Families will use two-way radios on a camping trip or at a theme park. In fact, family radios are a great way to make sure kids don’t get lost at the mall.

Walkie-Talkies and Two-Way Radios Are Too Big

That may have been true for radios designed 20 years ago, but definitely not now! Look at your iPhone or Samsung Galaxy and now look at the Motorola CLP1040 radio, which measures 3.5 by 2.0 by .75 inches. Or check out the digital Motorola DTR410, which is 5.2 by 2.3 by 1.4 inches. Lean and mean is the way of the future!

How Does a Two-Way Radio Repeater Work?

Learn how a two-way radio repeater works and discover if you need a repeater to expand the range of two-way radios in your fleet. In this article, we cover the basics so that you can be a better-informed radio consumer.

What is a Radio Repeater?

A radio repeater is an electronic device that takes a low-level or weak audio signal and it raises it to a higher physical level while amplifying it to a greater power. It acts as a bridge between portable handheld radios so that signals sent back and forth will be heard clearly over a wider distance.

How Does a Repeater Work?

The repeater takes the signal from a two-way radio and immediately re-transmits it at a different frequency and at a higher wattage than standard radios. It’s called a transceiver, since it can transmit and receive at the same time. A repeater communicates with all radio frequency receptors that operate on the same RF channel. Two different RF channels are used to carry the signals they receive and transmit. This makes them bi-directional with no danger of interference. This mode of operation is known as duplex. By comparison, when a push-to-talk switch is used on a walkie-talkie to transmit or receive, that is half-duplex operation.

Certain newer radio repeaters offer both duplex and single channel (simplex) modes. For example, the Vertex SZ-PAX-7045 Repeater, available at Tech Wholesale, can be used as a repeater or as a base station, by pushing the push-to-talk button.

Repeater-Capable Two-Way Radios

Not all two-way radios can be used with a repeater. If you know you’ll need to communicate over a wide range and plan to use a repeater, make sure your radios are compatible. High-quality two-way radios that are repeater-ready include the Motorola CLP Series radios and the Motorola RDX radios.

Do you Need a Repeater?

If you’re trying to communicate over a large area and especially if there are many obstructions, you may require a repeater. Water, air, structures and even a dense forest can absorb radio signals, causing a loss of signal clarity. The radio’s antenna height makes a big difference in signal range. If you’re operating in a valley and are surrounded by mountains (or tall buildings), you may notice reduced signal range. A repeater enhances radio signals both by re-transmitting from a higher location, with an external antenna, and by boosting the signal’s wattage.

Troubleshooting Two-Way Radio Issues

Are you troubleshooting two-way radio problems? Having issues with your walkie-talkie, especially if you just recently bought it, is frustrating. However, the solution might be easier (and less expensive) than you think. It may have something to do with the way you’re using it. Before you call up the dealer to complain, here are some ideas as to what might be causing your radio to not be working properly.

  1. Are your accessories fully plugged in? Check that accessories such as an earpiece or shoulder microphone are fully plugged in to the radio. The jack should click twice when you plug it in. Always plug in the accessory when the radio is turned off. When you turn it on, the radio can then properly register the added accessory, so that it will work properly.
  2. Is the radio charged? Make sure your battery’s radio is always charged. If the signal seems to be fading, it may very well be the fading battery. It is helpful to have a spare battery on hand, just in case, so you can eliminate any down-time due to a dead battery. Depending on your radio brand and model, see our Motorola and Kenwood radio accessories for batteries and chargers. Rapid chargers are also available that will greatly cut down charging time.
  3. Have you programmed all the radios in your fleet? If you’ve bought multiple two-way radios, but only one is programmed, you will need to program the others with identical settings so that they can communicate with each other. If you think this is the case, call Tech Wholesale at 1-888-Walky-Talky for information about duplicating settings for your particular radio model.
  4. Is the antenna broken? If the radio sees a lot of hard use in the workplace, such as on a construction site, rough handling of the radio may cause an antenna, especially if it’s a long whip antenna, to break. If this has happened, the radio might not be able to receive the signal. Antennas are typically inexpensive to replace.
  5. Do you need a repeater? If you are trying to use your radio over a larger area than it was designed for, you might need to use a two-way radio repeater. This device takes the audio signal from a radio and amplifies the power to a higher wattage and at a higher physical level, sending the signal back out on a different frequency. This greatly expands the range of those radios. For a very large distance, you may require multiple repeaters to cover the entire range.

Tech Wholesale is your best source for two-way radio expertise and the lowest prices on radios and radio accessories. As a Motorola Authorized Dealer and Kenwood Authorized Dealer, we have not only the best products but the greatest expertise with these radios. If you still can’t figure out what’s wrong with your radio, give us a call and we’ll help you get to the bottom of it!

10 Industries Where Two-Way Radios are Essential

Two-way radios are indispensable for business that rely on open, immediately lines of communication between workers for optimal service to customers and fast reaction times to a rapidly changing work environment. That would seem to encompass all organizations, but there are certain industries that especially benefit from the “always connected” nature of portable two-way communication. Radios help improve project management and make working groups more efficient, as miscommunication between team members is greatly reduced. Here are the top 10 industries where walkie-talkies make the world of difference.

  1. Retail Stores - Personnel can speak amongst themselves to ensure that shelves are kept fully stocked and customers’ needs are attended to without using the public paging system. This allows for a more seamless, professional business. Also, if someone spots a shoplifter, security staff can be notified discreetly for fast action.
  2. Hotels – Managers, cleaning and maintenance crews, restaurant staff, the security team and others are all spread out over multiple floors. Two-way radios allow for smooth, organized and discreet efforts on behalf of guests, while still maintaining a quietly professional appearance.
  3. Catering Companies – The work of caterers is time-sensitive, with perfect scheduling the key to customer satisfaction. Client requests, food preferences, deliveries of ingredients, food preparation, meal distribution and many other details can be organized to perfection by using a walkie-talkie system.
  4. Medical Practices – There are many moving parts of a successful medical practice – waiting room receptionists, nurses, doctors, cleaning staff and equipment technicians. They can all be organized effectively into a smoothly operating organization to provide the best possible care to patients, attending to individual needs.
  5. Car Dealerships – Whether it’s to request that a certain car be brought to the front from a back lot, check on the progress of a check-up by the mechanics or to speak with a manager or the finance department, car dealerships greatly benefit from two-way radios. The salesperson is able to continue to answer customer questions without any interruption in service.
  6. Warehouses - Shipping, receiving, loading, unloading, bookkeeping and more – warehouses have a dizzying maze of activities going on at the same time. A two-way radio system can help keep everyone on the same page for a smooth operation that stays on schedule to meet customer demands.
  7. Construction – Since they’re often spread out over a large area, two-way radios are frequently used by construction crews to communicate with others on their team, to relay information about a job, ask questions, call for additional workers or relate client requests. Coordinate multiple teams working on a big project and get that project done on time and within budget.
  8. Event Management – Hosting a successful special event requires the perfect coordination of many moving parts, from caterers and supervisors to technicians and security. Being able to communicate with everyone at once, or with a specific subset of workers, greatly increases efficiency.
  9. Farming – Especially when the farm is in a rural area where cell phone coverage may be spotty, two-way radios are essential, letting the crew cover a lot of ground while still staying in touch. Ensuring that workers have the supplies and equipment they need and can easily radio for help in the event of an emergency keeps a farming operation successful and safe.
  10. Security – In the field of security, no issue is too large or too small, and every second counts. With a robust two-way radio system, a security team can patrol a large area, quickly and discreetly calling for backup should a potential problem arise.

For customer-facing service companies like retail stores, hotels and medical practices, Motorola CLP radios are highly recommended due to their small, compact size and discreet hands-free operation. Indoor/outdoor businesses like farms and car dealerships spread out over a large area benefit from the robust Motorola RDX radios. Motorola digital radios are an attractive choice for event management and security teams, since they offer highly secure communications and the ability to speak to the entire team or just one person. Boost efficiency, communication, customer satisfaction and safety in the workplace, wherever that happens to be, with high performance two-way radios.

The Most Durable Two-Way Radios for Extreme Conditions

Extremely durable two-way radios for extreme conditions – do they exist? Yes, absolutely, and if you want the most rugged radios available, look to the U.S. military. Radios that meet military specification MIL-STD-810 are specially designed for the battlefield, and they’re built to withstand harsh environments. IP ratings are another standard for designating two-way radio toughness. When you see either or both listed in a walkie-talkie’s specifications, you know you’re getting a radio that has been tested under the toughest conditions.

Tough, Durable MIL-STD-810 Two-Way Radios

What does it mean when a two-way radio conforms to Military Standards 810 C, D, E F and G? It means that the radios have been tested for resistance to vibration, shock, dust and extreme temperatures. Radios such as the Motorola DLR1060 digital radio and the Motorola RMU2080 UFH radio meet these rigorous MIL-STD-810 specifications. They also have an extremely durable polycarbonate housing with built-in antimicrobial properties that inhibit bacteria growth.

Two-Way Radios with IP-54/55 Compliance

Ingress Protection (IP) is a rating system that tests the device’s level of protection from particles and water. IP54 indicates protection from limited dust and water spray from any direction. IP55 indicates protection from limited dust and low-pressure jets of water from any direction. The Motorola RMU2080 meets both MIL-STD-810 and IP-55. Other walkie-talkies that meet these extremely high standards include the Motorola RDV5100, Motorola RDU4100, Motorola RMV2080 and Motorola RMM2050. If you want a walkie-talkie that’s weather-proof but also economically priced, check out the Motorola Talkabout Radios. With compliance to IP54, they are designed for family and personal use, operating on the Family Radio Service (FRS) frequency band. This particular radio service doesn’t require an FCC license. They’re not as heavy duty as the business radios, but they will provide some degree of weather protection at a lower cost.

Guide to Adding an External Antenna for a Two-Way Radio

If you add an external antenna for a two-way radio, can you increase the range of the radio? Yes! But not all walkie-talkie models have removable antennas or the ability to be used with a repeater. For those radios with removable antennas, a particular model is only compatible with a certain type of antenna. Another option is to buy a radio that is “repeater capable.” A repeater receives a signal and retransmits it at a higher wattage or a higher level and in doing that, broadcasts the signal over a longer distance, increasing the range of your two-way radios. Base stations can be connected to an external antenna, which will provide more power and a greater signal range. Note that radio base stations are not portable, so they’re meant for those that will be using the radio from a fixed location. They can, however, communicate with portable radios and with repeaters.

Two-Way Radios with Removable Antennas

Certain Motorola radio models come with a removable antenna-for example, the Motorola RDV5100 VHF radio and the Motorola DTR550 digital radio. It all has to do with the compatibility of the connector. If it doesn’t specifically say which radio the antenna is designed for, look at your radio’s antenna connector. Is it an SMA female, SMA male or J female? Note that Motorola/Vertex has their own standard of SMA connector. Using a long whip antenna will give you increased range when outdoors and if your radio features a removable antenna, you can change to a stubby antenna for more convenient and compact indoor use. However, you must make sure you use the correct antenna for your radio.

Adding a Two-Way Radio Repeater to Boost Signal Range

One effective way of adding an external antenna to a two-way radio is to use the radio with a repeater. This will significantly increase the range of your portable radios. The repeater, usually placed in a high location, receives the signals from the handheld radios and then repeats those signals at a much greater wattage and on a different frequency. It also receives signals and sends them back to the radios. Only certain walkie-talkies can use a repeater. Some of these radios include the Motorola RDV5100 VHF model, the Motorola RDU4160D, the RDU4100 model and Motorola CLP Series radios. The Vertex Two-Way Radio Repeater also serves as a base station and it communicates with your handheld radios.

Two-Way Radio Base Stations and External Antennas

A base station is a two-way radio that stays in a fixed location. It connects to an external antenna to provide far greater power and signal range than the average portable radio. They can connect to mobile handheld devices as well as repeaters to extend the range even more. An external antenna must be matched (or tuned) to the same frequency that your radio is broadcasting on.
