Channels Frequency is a popular commercial radio station based in Philadelphia, Pennsylvania broadcasting on KDSA-FM. The station is operated by VM Broadcasting, a publicly traded company that also owns a number of television stations. In addition to Channels Frequency, the same company owns XM satellite radio. The company does not own the airwaves directly but licenses the use of the airwaves to various radio channels and affiliates. This is done in an effort to generate revenue from listeners to the various programming they offer.
How does Channel Frequency get the content that it does and offer on its airwaves? It uses what is called a virtual channel number. This is a unique number that is assigned to each program and artist that will be played on Channels Frequency. If an affiliate for the station obtains a listing of songs that are being offered along with the artist’s performance time and date, it is then possible for a listener to play the song or artist without having to search for a direct recording. This is known as a real channel broadcast and is a more efficient way for a station to showcase their music and artists.
The technology used by Channel Frequency is relatively modern. It has a digital signal processor (DSP) that processes the digital information received from the online servers that provide internet access. The processor converts the information into actual sound signals and then broadcasts them over a network of satellite channels. The output from the DSP is a digital signal that can be converted back into an analog signal that can be heard through an audio amplifier. For most markets, an AM station must have a digital channel frequency that is able to reach all areas in a fifty mile radius. This is a benefit to both advertisers and consumers alike because it allows both to receive and send the same message at the same time.

Each radio station that wishes to participate in the Channel Frequency service must first purchase a virtual channel number. Once these numbers are purchased and placed into a database, a station’s slot in the Channel Frequency is immediately filled. To participate in the service, a station can choose to either maintain their own list of virtual channels, or they can submit their web site’s number to a database in exchange for a fee. In either case, stations must abide by the rules of the service in order to remain within the allotted slots on a real channel number.
Advertisers have also found this option to be very advantageous. Most people only pay attention to a single radio host during their daily commute, so paying for a spot on another radio station during their break is not usually a top priority. When a station plays a song that is popular, they can increase listenership exponentially when they submit their web site’s virtual channel number to a server maintained by the Channel Frequency service. Not only does this tactic allow them to stay within the allotted slots, but it also allows them to play any song that is popular without advertising to those who are not interested. Since more people tune into their favorite radio hosts when they are not at home listening, the more popular songs will likely find themselves playing when their favorite radio host is not around.
Radio stations that participate in the Channel Frequency service are charged on a monthly basis. Unless you are a professional DJ, it may not be worth your while to purchase more than one Channel Frequency ID (Channel Frequency ID’s) for use on multiple recording studios and radio stations. If you have a large personal radio station budget, it would probably be worth purchasing three or four Channel Frequency IDs to build a station database. However, if you only intend on using the service for a personal radio station, it would be better to purchase only two or three Channel Frequency IDs for the same amount of money.
Some professionals utilize their knowledge of the radio spectrum to direct targeted markets to their music. For example, they can often be found in crowded areas looking to promote a track. If they are able to get their song played in a busy area, they may be able to increase listenership. In order to maximize the use of the Channel Frequency service, recording artists should purchase at least two channels. The added channels could be used to promote upcoming albums, singles, or songs for the artist to promote.
There are some limitations to the usage of the Channel Frequency service that must be considered. The lower the channel width, the better chances of the station being heard by all residents of the building or apartment unit where it is located. As a general rule, the wider the channel, the better the chances of being heard by everyone in the building. If you plan on placing your radio transmitter on top of the apartment unit, the chances of it being blocked by neighbors and in some cases, the owners of the apartment units themselves, is also an issue that must be addressed. However, in the case of a shared radio ownership, if everyone shares the same band, it may not be an issue.
