Two-Way Radio Channels – How many do I need?

Two-Way Radio Channels – How many do I need?

The short answer is – the number of two-way radio channels you pick should be the same as the number of teams in your operation who will share communication.

Imagine you are responsbile for organizing communication at a large resort complex. For safety you will need to have one common channel for all employees. For normal communication, however, you’ll want to assign one channel to security staff, another channel to house-keeping staff, another to recreation supervisors and so on…

Channels divide two-way radio communication, so that users can communicate with their team members and not be interrupted by conversations in a separate division.

Your two-way radios will come set-up with a particular frequency on each channel. Remember to check the frequencies in your area and re-set your channels to frequencies that are not being used by others nearby.

A word about Privacy Codes – Quiet Talk Codes (QT), as they are also known, are not actually private. The use of “privacy codes” simply filters out communications from others using the same frequency. Anyone on the same frequency could still hear you so long as their radio is set to not filter for a “privacy code”.

Why choose using Two-Way Radio?

Why Two-Way Radio?

Two-way radio is the preferred method of communication in many industries, including manufacturing, law enforcement, commercial transportation, hospitality, film production, utilities, and government.

This is because the benefits of two-way radio trump competing communication platforms in several important ways:

Reliability

When cell networks become overloaded during peak hours or emergencies, two-way radio continues to function. Furthermore, most radio infrastructure includes power redundancies in case of electrical outages. This often makes two-way radio the only means of rapid communication in the event of systemic power loss.

Enhanced Audio

Communication within industrial environments is often difficult due to background noise, but two-way radio uses noise-cancellation technology to increase clarity. Audio output is notably louder than most cellular alternatives. And while cellular systems often experience sound drop-offs and disconnections in large structures or underground, two-way radio systems can be set up with radio repeaters and distributed antenna systems to ensure voice clarity throughout a campus.

Easy Broadcasting

A “one-to-many” option allows everyone holding a radio to hear a transmission. This makes it easier to broadcast to everyone on a team and coordinate action. As a plus, it also discourages employees from abusing the communication network and wasting time by “goofing off.”

One-Time Investment

While cellular networks require monthly subscriptions and long contracts, radio only requires a one-time purchase and installation outlay. After that, the system is owned and operated by the purchasing party. The only other costs come from routine maintenance. Depending on size and scope, a two-way radio investment might pay for itself in just a few months compared with a cellular system.

For firms who need a short-term communications solution or simply do not wish to own a system, affordable two-way radio rentals are also available.

Durability

NNTN8383 INC RSM under waterTwo-way radios are designed with outdoor use in mind — meaning they perform better than cellular devices in a wider variety of environments. A 2014 report comparing communications network failure rates found that 4-8% of industrial two-way radios failed annually. In contrast, cellular devices fail at a rate of 18-20% annually and are not built with outdoor use in mind.

Productivity

A quality radio system increases the speed of communication, allowing mission-critical information to get through to the right people instantly. Rather than having to walk over to deliver a message in person or type out a text, one button press is all that is needed to get in touch. The ability to communicate instantly also reduces work stoppages in the event of mishaps, as personnel can be alerted quickly.

Accessories

Smartphones aren’t the only devices which feature a wide array of accessories. Users of two-way radios can invest in a variety of products to increase the comfort and ease of use of their systems. These include headsets, speakers, car mounts and even lapel microphones.

Evolving Technology

Radio manufacturers innovate to compete with other technologies and provide in-demand features. Newer radios come with GPS and location-tracking technology, especially helpful for dangerous jobs or when employers need to keep an eye on their employees’ movements. Other options include text messaging, call forwarding, and even instant notifications to report malfunctions and limit downtime.

Digitalization

The transition from analog to digital, apart from driving down the prices of two-way radio systems, has resulted in many other benefits. Using technology such as TDMA (Time-Division Multiple Access), these include better noise reduction and voice clarity, extended range, more privacy controls, and longer battery life.

Two-way radios are helpful in many business environments, from construction sites, to underground mining operations, to college campuses, to manufacturing facilities. Greater audio volume, sturdiness, and even the ability to command more authority in emergency situations contribute to the versatility this technology.

Anytone AT-D868UV dual-band VHF UHF DMR Portable and AT-D868S Mono-Band DMR MobileRadio

Anytone AT-D868UV dual-band VHF UHF DMR Portable and AT-D868S Mono-Band DMR MobileRadio

http://www.anyradios.com/product/anytone-at-d868uv-gps-dual-band-dmr-tier-i-ii-144-430mhz-analog-digital-radio-fcc-programming-cable/

Qixiang Electron Science & Technology Co., Ltd, the Chinese manufacturer that produces the Anytone line of two-way radios, announced its intention to release the Anytone AT-D868UV, a dual-band VHF (136 – 174 MHz) and UHF (403 – 480 MHz) DMR portable radio in the United States on March 1, 2017.

DON’T MISS: Baofeng DM-5R launches, becoming the first dual band DMR radio

Unlike the recently announced Baofeng DM-5R, this new dual-band portable will support both DMR Tier I and Tier II operation, making it compatible with ham DMR repeaters, which utilize two-slot TDMA technology.

The Anytone AT-D868UV will also offer three power levels of 6W/2.5W/0.5W. One feature of this radio that many hams will find particularly useful is that it will auto-sense digital or analog transmissions and connect accordingly, making mixed mode operation a treat. In addition, the radio will feature 1,000 channels, VFO tuning and for DMR operation, it will offer two channels per frequency. Additional specifications will include:

A 1.77 inch TFT color LCD display;

12.5 khz/25 kHz analog operation and 12.5 kHz digital DMR operation;

CTCSS/DCS and DTMF/2TONE/5TONE encode and decode;

Optional GPS support.

In terms of battery options, the Anytone AT-D868UV will come standard with a 2,000 mAh Li-ion battery, however higher capacity 2,400 mAh and 3,300 mAh Li-ion battery options will also be available for purchase. Pricing for the Anytone D868UV is expected to be around $200 USD.

In addition to the Anytone AT-D868UV portable radio, Anytone will also introduce its new mono-band DMR mobile radio, the Anytone AT-D868S with the same technical specifications, however the power output levels will be 10W/5W/2.5W/0.5W. Both radios will be FCC approved and supported with an enhanced software programming package.

Anytone also announced that several additional Anytone radios are planned for release later in 2017, including the dual-band DMR mobile , the Anytone AT-D5888, which will be a mobile version of the Anytone AT-D868UV.

Wouxun KG-UV8E Tri band amateur radio

Wouxun KG-UV8E Tri band amateur radio

What is better than a dual band handheld two way radio? Why, a tri-bander, of course. Now, it’s here. Say hello to the Wouxun KG-UV8E tri-band transceiver.

The KG-UV8E is based on the very popular Wouxun KG-UV8D, the dual band portable handheld radio best known for its large color display, cross band repeat capability and true simultaneous two band reception, all at a very low price point. At the moment of its introduction in 2014, the KG-UV8D was an instant hit, and it is still the handheld of choice among many hams today.

However, the 2 meter and 70cm bands are becoming crowded, and many hams are moving to the 1.25 meter band for some breathing room. The problem? There aren’t a lot of 1.25 meter radios out there, and the ones that are available tend to swap the beloved 2 meter band for it. This means amateurs had to choose between a dual bander with either 1.25m VHF and UHF, or 2m VHF and UHF. If you used a handheld for both, you either had to carry two dual band radios, or give up a VHF band altogether.

The solution? Wouxun created a portable handheld that includes all three. It’s the KG-UV8E, and it’s available now from Buy Two Way Radios!

The Wouxun KG-UV8E has all the same features of the KG-UV8D along with the feature upgrades of the KG-UV8D Plus. In fact, for all intents and purposes, it is a UV8D Plus, with the addition of one extra band for full transmit and receive on 1.25 meters from 222Mhz to 225Mhz.

The Wouxun KG-UV8E supports the following bands and frequency ranges:
RX Only RX and TX
Band Frequencies Band Frequencies
VHF 136-174MHz VHF 144-148MHz
VHF 220-260MHz VHF 222-225MHz
UHF 400-520MHz UHF 420-450MHz

With an apparent over saturation of dual band amateur radios covering the 2 meter and 70cm bands already on the market globally, coupled with an increase in activity on the limited frequencies within those two bands, more and more amateurs are searching for some other space on the radio spectrum they are licensed to use, but isn’t quite as crowded. The obvious choice? It’s the 1.25 meter band, or as more commonly, if not inaccurately called, the 220MHz band (the frequencies licensed for ham use are actually between 222Mhz and 225MHz). Underused for years and all but forgotten, 220MHz is coming back to life, and in a big way.

The advantages of the 1.25 meter band are obvious and easy to list:

Accessible to all licensed amateur radio operators
Still considered VHF, just below UHF
Between 1.25m, 2m and 70cm, 1.25m is considered the band with the best propagation
repeaters are available, but are not as crowded
Not as active, so it is quieter, with less interference

There’s just one disadvantage. Access to the band has been a challenge, simply because there aren’t many 1.25 meter radios on the market. That is, it was a challenge, until now.

Wouxun intends to change all that and give amateurs what they want and need, one handheld radio to access the three higher frequency bands all technician, general and extra class amateurs are licensed to use, and to maximize the entire experience with a range of capabilities and features one would only expect from a handheld transceiver costing much more. They may just do it with the KG-UV8E.

But don’t just take our word for it. Take a look at the Wouxun KG-UV8E and tell us what you think.

Tytera TYT MD-9600 DMR Digital Mobile Radio

TYT MD-9600 Dual Band DMR Mobile Radio

Tytera shook the world of digital radio in 2015 with the introduction of the MD-380, a portable handheld capable of both DMR and analog operation at an analog radio price.
Digital radios were outrageously expensive, and were priced out of the hands of many.
Then the MD-380 came along. It changed everything. For the first time, DMR was truly available to the masses, so to speak. Amateur radio operators on a Baofeng budget could experiment within the digital realm without spending hundreds of dollars on digital equipment, and because the UHF version was Part 90 type accepted for commercial use, small businesses could afford to keep up with their competitors and migrate to digital without the exhorbitant cost. The MD-380 was a game changer, and turned Tytera into a respected brand in the DMR marketplace almost overnight.

Now they are about to do it again. Get ready for the Tytera TYT MD-9600 Digital Mobile Radio!

Yes, that’s right, the long-awaited announcement is here. Tytera has introduced a new mobile two way radio capable of operation in both digital and analog modes.

According to Tytera, the MD-9600 operates on 400-480MHz frequencies at up to 45 watts (UHF model) or 136-174MHz VHF at up to 50 watts (VHF model). As a DMR radio, It uses Time Division Multiple Access(TDMA) technology and is compatible with MotoTRBO Tier I and II.

The TYT MD-9600 boasts 1000 channels and 250 zones with 16 channels for each zone. Features include Private Call, Group Call, All Call, a lone worker mode, ANI function, encryption, short text messages, CTCSS/DCS encode and decode, power save mode, low power alarm, an emergency alarm and VOX capability. The console features a color LCD display and four programmable function keys. The hand mic also has four programmable keys, in addition to the two built-in LEDs and full DTMF keypad.

The MD-9600 is also quite versatile. it’s not only PC programmable, it’s firmware upgradeable as well, a flexibility most other portable and mobile transceivers lack.

The expected release date is sometime in 2016. No price point has yet been set or announced, but as soon as we have pricing, the MD-9600 will be available for pre-order at twowayradio.us
