Everything You Need to Know About DAB Radio

What exactly is a dab? It stands for "aido dabble" in the jargon of radio hams.dab+ digital broadcast receiver It is one of several new innovations aimed at improving the quality of digital transmissions being sent from the typical transmitter to the receiving antenna on a handheld device, such as a mobile car radio. By replacing the dipole antenna with a much wider bandwidth-efficient multi-mode carrier capable of transmitting digitally, many believe this is already being used on many amateur radio stations and by the general public.

Dabblers consist of a transmitter and its associated antenna that are tuned to the same frequency.dab+ digital broadcast receiver dab+ digital broadcast receiver In order for the transmitted signal to be received, both the transmitter and the antenna need to be tuned to the same frequency. Because the signal strength is inversely proportional to the applied frequency, the more the transmitter is tuned to a lower frequency (in the case of dabblers), the weaker the audio quality will be once the transmitter is within a few feet of the receiving antenna. However, when the transmitter is within hearing distance, it creates a superheterodyne effect, which increases the perceived audio quality.

DABblers are used in many circumstances where only one station is being transmitted, such as an FM station transmitting over the air or a conventional AM station.dab+ digital broadcast receiver dab+ digital broadcast receiver Such devices are sometimes used as station monitoring systems, enabling regular citizens to tune into a specific station for background information. Some companies have adapted the dabbing concept to include computer software that allows people to tune into a broadcast, such as a news ticker or weather forecast. Some enthusiasts enjoy tuning into the audio portion of an aircraft for a personal enjoyment of the broadcast and/or to learn something new.

Some countries, including the United States and United Kingdom, allow dabblers for private use. In the United States, dabblers must be registered with the FCC, which requires them to pay a fee based upon the perceived value of the audio transmission, in addition to covering their own expenses for equipment, transmission, and power use. Additionally, the FCC requires that the transmission be encoded with a digital code, which ensures privacy and prevents the same number of people from tampering with the signal. The transmission can be decoded by another receiver using a digital receiver, but this type of service is not widely used.

Most countries, including the United States and United Kingdom, have laws limiting who can transmit the digital signal. For example, the UK's Audio Visual Industries Authority (AVI) controls who is allowed to receive and use digital transmission. In the United States, individuals are only allowed to use dabblers that are purchased from AVI-approved dealers. The Federal Communication Commission also has issued regulations that govern the amount of money a person may pay for dabblers and the amount of times they may record their reception.

DAB Radio may provide a useful service for people interested in curbing unwanted radio noise, but the cost of acquiring a dabber and maintaining a working connection can be very expensive. There are solutions that make it possible for people to keep their own DJ accounts, which work much like mobile phone plans in that a subscriber can pay to have a signal periodically updated by the radio station. The subscriber can then choose whether to have the signal forwarded to their personal computer or the primary receiver at home. A person can even have their subscription upgraded to include their home radio station if they so desire.
