Best Radio Accessories for Your Walkie

To really optimize your chosen walkie talkie set, you’ll need more than just the receives themselves. Whether you’re using them for personal, recreational use or to keep things safe and productive while on the job, there are a number of accessories that you can use to ramp up your walkie talkie’s performance. Here are just a few of the best radio accessories.

  • A Headset. While a walkie talkie is already a very convenient tool for long distance communication, it’s not exactly a hands-free device. If you’re doing a job that requires both hands as well as communication with your co-workers, you’ll want to invest in a headset that goes with your radio.
  • An earpiece. For even more discreet, hands-free communication, hook your walkie talkie to your belt and use an earpiece to talk to your coworkers. Most of these accessories have push-to-talk features that make it easy to speak when you want to and turn them off when you don’t.
  • A belt holster. Whether you’re using a separate headset or not, a belt holster is essential for keeping your radio on hand at all times. These swivel holsters make it easy to remove the radio without interrupting your duties.
  • A multi-unit charger. If your entire family or team of employees uses walkie talkies, you’ll want to purchase a multi-unit charger that charges multiple radios at once. It’s a huge time saver, not to mention a space saver when you’re charging your radios on the counter!
  • A high capacity lithium-ion battery. If you’re tired of your walkie talkie dying in the middle of the day, upgrade the standard battery to a high capacity battery that holds a charge for much longer. When fully charged, this type of battery lasts for 9 to 12 hours.

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.

How to Get Two Different Walkie-Talkies to Communicate With Each Other

If you have one type of walkie-talkie and your friend has another, you may wonder how to get them to communicate with one another. While many people think that two different walkie-talkie brands won’t work together, these simple steps will show you how to get them to “talk.”

  • Set your walkie-talkies to the same channel. If they won’t communicate with one another, then move on to the next step.
  • If your walkie-talkies won’t communicate on the same channel, check for CCTCSS (or Continuous Tone Coded Squelch System) blocking. If you have CCTCSS activated, it sends a tone along with your voice when you speak. This isn’t detectable by a person, but it is detected by the receiving radio. If the tone that is detected isn’t the tone that the accepting walkie-talkie is “told” to accept, however, it won’t let the message through; this is why some messages won’t come through from other brands of devices. To fix this, simply switch off the CCTCSS functions on your walkie-talkies.
  • Another type of signaling is DCS, or Digital Coded Squelch. This is similar to CCTCSS, but instead of sending a tone, it sends a digital code. If your radios still won’t communicate with one another, they may have DCS codes that aren’t compatible. Simply turn the DCS feature off and they may start to work together.
  • Depending on if your radio works with FRS or GMRS frequencies, the channel numbers may be different. You may think that your radios are on the same channel, when actually channel 1 on one radio is channel 8 on the other. If this is the case, you’ll want to look up the channels and their corresponding channel numbers on the other type of frequency.

Things Walkie-Talkies Do Better Than Cell Phones

While your cell phone is great for sending photos to friends and making quick, everyday phone calls, there are a number of reasons why you should also own a two-way radio. These types of radios are essential in the case of a large-scale emergency, and they also enable you to get in contact with family or medical personnel if phone lines go down. Here are just a few things that walkie-talkies do better than cell phones.

  • Walkie-talkies are much more durable than most modern cell phones. Many types of walkie-talkies are waterproof and resistant to dropping or sinking, and they even float if they fall into deep water.
  • Walkie-talkies are much more affordable than cell phones, and they don’t require monthly plans to use. This means that all it takes to operate a walkie-talkie is a one-time purchase.
  • Walkie-talkies provide instant communication by simply holding down a button. Unlike cell phones, which require you to dial a number and wait for the other party to answer their phone, these types of radios can instantly put you in contact with another person.
  • Walkie-talkies don’t require phone lines to use. This is invaluable in the case of a widespread emergency, because phone lines often become so congested that they go down completely. In the case of a natural disaster, robbery, fire or some other type of emergency, a walkie-talkie is your best bet for getting in touch with emergency services and family members.
  • Walkie-talkies are much easier to use, especially for children and the elderly. If you have family members who don’t have cell phones, make sure that they know how to use a walkie-talkie in case of an emergency. In most cases, this simply means pressing one single button and speaking into the device.

What is Frequency Hopping Spread Spectrum (FHSS)?

If there is anybody who hates the prospect of interceptions more than Peyton Manning or Tom Brady, it is anyone attempting to transmit radio signals and hoping to avoid narrow band interference and having their signals “picked off” the way a larcenous defensive back going for the pigskin does in a football game.

Keeping Your Transmission Safeguarded

If you want your radio signals to be less susceptible to interception, Frequency Hopping Spread Spectrum transmission is the way to go. Defines as “a means of transmitting radio signals by shifting a carrier across a number of channels with a pseudorandom sequence that the sending and receiving station knows beforehand,” Frequency Hopping Spread Spectrum (FHSS) is employed as a multiple access process in the Frequency Hopping Code Division Multiple Access transmission scheme. Repeatedly switching frequencies when transmitting a radio signal makes it harder to jam or mess with that signal by any agent with potentially malicious intent.

The Benefits of FHSS

FHSS provides several clear-cut advantages. First, the likelihood of narrow band resistance is slim with FHSS because an interfering signal gets relegated to the background with the spread signal. Second, when a narrow band receiver detects FHSS signals, the signals give the appearance of an increased level of background noise, making their interception unlikely because the pseudorandom transmission hopping sequence has to be known. Military radars are harder to target with FHSS than radars on a single frequency. Third, FHSS transmission signals cause very little interference, maximizing the use of the bandwidth so they can share frequency bands with a number of other types of conventional transmissions.

Reflections, noise and other external factors in the environment have a minimal influence on this technology, which is well-suited for installations that cover large areas where several co-located systems might be required.

When the military uses the FHSS Algorithm, it uses cryptographic techniques that encrypt communications and generate the channel sequence to be used during the communications session.

How and When to Use a Throat Microphone

When noise is amped up to the max, a mic at the throat can be the best way to convey your own voice.

Pilots who have to communicate their messages in extremely noisy environments frequently use throat microphones. Unlike regular microphones, which pick up sounds via acoustic vibrations in the air, a throat mic attaches directly to the throat so that source of the audio input is the larynx itself. By doing so, the throat microphone conveys a vocal sound that is crystal clear, unimpeded by competing noise and easier to understand.

Understanding the Basics of the Throat Mic

A throat microphone, which filters out acoustical background noise, works by being securely fastened around the neck with transponders that rest on the throat. Also known as mic pickups, the transponders, which are usually used in pairs, make direct contact with the throat. A throat strap is fastened at the back of the neck, and one or sometimes two ear pieces are placed in the ear. It may take a little bit of trial and error to locate the perfect spot on your neck for the transducers to work optimally, since every neck has a unique shape and contour and everyone’s Adam’s apple is a different size.

Once the microphone’s output cable is plugged into the transmitting or receiving device, you’re ready to start communicating by using your throat with no “middle man.” The mic cable goes into the audio input port if you are plugging it into a computer or a cell phone or smart phone.

The PTT (push to talk) button is used to talk on the microphone. If you are using a wireless microphone, to receiving device should be tuned to the broadcasting frequency that is found either in the manual or right on the microphone’s box. The frequency of each throat microphone is unique.

How to get the Most Range from Your Two Way Radio

One aspect of two-way radios that too often turn into a one-way ticket to disappointment is manufacturers that advertise an expected range that ends up not being attainable. Too often, a two-way radios actual range falls far short of what “optimistic” manufacturers trumpet in their literature and advertising.

Tips and Tricks for Extending Two Way Radio Range

There are, however, ways that you can often boost the amount of range you are currently getting from your two-way radio. For radios that support General Mobile Radio Service (GMRS) channels, which are land-mobile FM UHF frequencies designed for two-way communication over a short distance, make sure that you are actually using a GMRS channel rather than an FRS channel. FRS (Family Radio Service) channels are a two-way communications method designed to be used only over a very short distance and have a maximum output of 500 mW.

The Federal Communications Commission (FCC) does not allow transmission on an exclusive FRS channel at more than half a watt of power. Anyone’s radio using an FRS-only channel will transmit using only “low power” mode. The FRS-only channels are 8 through 14. Channels 15 through 22 are exclusively for GMRS, and channels 1 through 7 are shared by both FRS and GMRS.

Use high-power mode on your two-way radio, or else you will not achieve maximum range. Low-power mode cuts down on the amount of output power your radio is using. A battery that is not fully charged can also compromise a two-way radio’s range capability. A battery with a low charge results in a radio with less transmission power.

Bonus Tip

Two-way radios also have a monitor channel feature that allows users to check and see whether a channel is clear before transmitting. When this feature is enabled, the channel is opened and transmission signals too weak to be audible when the radio is in normal mode can now be heard, although often with a considerable amount of static.
