I recently started watching NASCAR and I was wondering how the drivers communicate with the pit.

Wow. The newest radio accessory is incredible. I mean it is just so stunning so advanced. I pity those who grew up without the radio accessory.

NASCAR drivers use a unique radio system that is built in to their crash helmets. These are occasionally customized to suit the individual wearer. In addition to this, there is a push-to-talk button (exactly like the one found on a walkie-talkie), which is situated in the steering wheel. A wiring harness connects the various components together and a separate battery operates the whole thing. The signal is broadcast via a whip antenna that is attached to the roof of the car. In this fashion, NASCAR drivers are able to communicate with pit crews.

In addition to this, most cars are outfitted with a spare Motorola two-way radio that is within easy reach of the driver.

A firm out of Atlanta, Georgia named ‘Racing Radios’ provides the vast majority of the radios used in NASCAR races. Racing Radios have provided equipment to NASCAR races for 30 years or so; they are a trusted firm, creating all the standard NASCAR radio technology and also providing custom radios/peripherals for individual drivers.

According to Racing Radios spokesperson Tony Cornacchia, the majority of NASCAR drivers prefer to buy their own specialized equipment from the firm.

Because so many teams are racing and so many people are working on the race overall, it is not uncommon for NASCAR events to feature 100 FCC licensed radio broadcasts at any given time.

Racing Radios is the company that programs the individual frequencies, not only for drivers and pit crews, but also for staff, officials and security personnel. RR do such a good job, that neither drivers nor pit crews suffer regularly from interference or dead spots. Now that’s something.

According to Terry Boyce of ‘HowStuffWorks’, “Many teams outfit their entire pit and support crews with custom-engineered, hand-built headphones and two-way radios ordered through Racing Radios. Multi-car teams may choose to connect even more people through their radio communications network. Active Noise Reduction (ANR) technology helps to cancel out distracting background noise. Exceptional communication is one of the reasons a 21st century NASCAR pit crew can change four tires and refuel a race car in around 13 seconds — and do it 10 or more times in a single race”.

The Different Types of Two Way Radio

The basis of the post is to make you consider what in life is important and what does getting the new radio earpiece really mean to people

A two way radio is also known as a transceiver. These radios are used for both for sending and receiving data or signals. These radios can either work on analog technology or a digital technology. When analog technology is used in these radios, the transmission can be done clearly even for very weak signals. However, in analog technology, only one thing can be done at any given time i.e.
data can either be vent or received. When digital technology is used, data can be sent and received simultaneously and also more data can be sent.

Two way radios come in two styles. These are duplex and simplex styles. In the simplex radio, only one channel can be used at any instance of time. This means that only one person can send data at a time. The most popular type of a simplex radio is the walkie talkie.
The duplex radio is the one in which different channels are used for transmission of data. This means that any given time, the use can both send and receive data but using two different channels.
The two way radios are generally of two types. These are Family Radio service, FRS, and General Mobile Radio service, GMRS. The family radio service is mainly used as a personal radio that facilitates two way communications. The range within which these radios can operate is two miles.

These two way radios operate on very low frequencies that allow people in close proximity to communicate with each other. These radios are not suitable for a long range communication. These radios also have special bands on which they operate and are not so powerful that they can be used on a daily basis.
In addition, these radios operate the best in a line of sight. These radios cannot operate very effectively when there is an obstruction or the terrain is not plain. These types of radios cannot work well in mountains. The family radio service radios are very affordable as they mainly cater to the needs of the families.

They also have features best suited for personal needs.
The general mobile radio service radios are fast replacing the family radio service. One of the main reasons for this is the fact that the general mobile radio service radios can be effectively used for communication over long ranges. These can operate within a range of 20 miles.
These radios also operate the best when there are no obstructions and the terrain is plain. These two way radios cannot be efficiently used in hilly areas. These radios are very powerful and are best suited for use in military organizations. These types of radios are expensive and a user also requires a license to operate these radios.

These radios come with a lot of features. Most of these radios these days have a feature that tells about the weather. These also have features that can be used for navigation purposes. These 2 way radios are generally hand held and easy and convenient to use and operate.
