Organizations such as hotels, schools, and manufacturing plants use two-way radios for their daily operations. Just pressing a button to talk to a group of employees is simple and efficient. Problems occur when a manager wishes to talk to one employee. A standard feature in DMR digital radios called Private Call solves this issue.
How Private call works
Private Call allows a radio user to place a call to just one user without changing the channel. This feature is essential in security or emergency situations when just one person needs to receive the orders. It’s also key in any other situation that requires a private conversation between two radio users.
The Private Call feature works best on two-way radios with a display and a keypad. The process is as simple as using the MENU button to select the receiver’s name from a contact list pre-programmed into the radios and then, press the push to talk button.
The DMR Private Call feature also works on radios without a display and a keypad. However, since there is no possibility to see or scroll from a list, only the side or top buttons can be pre-programmed to privately call a specific person such as a supervisor or team leader.

If you recently bought two-way radios with any of the following DIGITAL standards listed on the box: P25, DMR, IDAS or NXDN, the radios are DIGITAL. If it does not list any of the noted DIGITAL standards, then the two-way radios are ANALOG only.
Why is this important? Well, many two-way radios prominently list a technical filtering feature by the common marketing name of DCG (Digital Channel Guard) or DPL (Digital Private Line) with DPL being the most widely used. The real name of that filtering feature is CDCSS (Continuous Digital Coded Squelch System). Since the word DIGITAL is in the description, it may give the impression that it is a Digital radio, but it is not.
CTCSS and CDCSS are a set of filters that reduce interference from other users when sharing the same frequencies. The CTCSS codes are an older set of filters used in the 50’s when two-way radios were just coming into use.
ANALOG only radios will just list the power rating, channel capacity, CTCSS and CDCSS as part of the selling features. ANALOG only two-way radios will never be able to work in Digital mode. They will not have the advantage of improved battery life, range, PRIVACY, caller ID and other features and functions true Digital radios have.
ANALOG and DIGITAL two-way radios of equal quality are almost equal in price and Digital radios are compatible and work with ANALOG radios. So the next time you are looking to buy two-way radios pay attention to the label and remember that if it does not say P25, DMR, NXDN, or IDAS, it is not DIGITAL.

Doing research on two-way radios will give you a lot of product information, but it just isn’t the same as hearing about a real life experience. Here we look at three different instances when professionals invested in two-way radios, the goals they hoped to achieve, and their level of satisfaction to help you learn more about what features are right for you.
A two-way radio solution for Carroll County, TN emergency services
Carroll County emergency services had been using a dated radio system to communicate that just didn’t give them access to all areas in the six hundred square miles that they service. When Terry Bradshaw saw it was time to update, they choose the DMR Tier 3 800MHz trunked network that provided them with capabilities beyond their expectations.
They were able to communicate in areas that they never had before, allowing them to respond faster and more efficiently. Plus, with encrypted communication, they were able to keep sensitive issues secured. While the Carroll County firefighters knew the product was of premium quality, they were still pleasantly surprised with the multitude of features. Click here to read more.
Synchronizing safety efforts with superior two-way radios in Kansas City
When an electrical company in Kansas City saw the flaws in their current radio system, they decided to take action. The primary issue was three crews that were regionally based were all using different radio systems, and when they would have to come together for storm situations, communication was a major problem. Coverage was also problematic because there were locations that there was little or no way to communicate.
Using past experiences and quality evaluations, they choose the DMR Tier 3 trunked network and haven’t looked back. Staff members are more confident when it comes to communication because the two-way radio system is reliable and always available. Response time became faster, and the ability to service the community improved tremendously. More details.
Premium communication for events at the University of Connecticut
The University of Connecticut has some pretty serious stadiums for sports, trade shows, banquets, and much more, and when these events were taking place, the staff wanted to find a better way to communicate. Wireless communication is essential for the arena setting, and cell phones couldn’t handle the job because of the large number of people in attendance that were also using devices.
Dropped calls were an issue until they were introduced to the Hytera products and PD7 Series. They soon discovered that they could have seamless communication, even over the noise level of the crowds. The system was cost-effective and helped them host events for tens of thousands of people safely and efficiently. Learn more here.

Let us be your communication solution, so you don’t miss a single piece of information in your day due to failed calls or locations challenges.Read More
P25 is the digital standard for public safety grade two-way radios. Offering very high levels of encryption, trunking formats, GPS and over the air programming combined in an industry wide accepted format. This format guarantees that, if the two-way radio is P25 standard, it will work with other P25 standard two-way radios even from different manufacturers. This allows Police, Fire and other public safety departments to be able to communicate with each other during an emergency, yet maintain their private networks during day to day operations.
DMR (Digital Mobile Radio) is the private industry version of a digital standard. Radios from multiple vendors designed with the DMR standard are guaranteed to work with each other. A Tait DMR two-way radio will work with a Hytera as well as Vertex Standard and MOTOTRBO. This offers flexibility as well as healthy competition when customers are trying to decide which product to purchase. Offering features such as one to one, one to all, group calls, GPS and text messaging, the DMR standard creates a new level of utility for the two-way radio.
DMR repeaters are designed to allow two users to share the same repeater at the same time without interference. This provides companies a two for one feature. Presently in analog operation one repeater is required for each group.
DMR has also opened the door for software designers to develop software products that will work with the radios. Just like smart phone applications, DMR applications are now offering value added features such as work flow reports and trouble tickets. With all these features available to the user, DMR still provides for analog communication. This guarantees a smooth migration with older legacy radios that customers may not be able to replace now.Read More
