Jamming Along The Airwaves


When I hear other radio listeners complain, ‘How come this radio station not playing my favorite song?’ Well, you have to look at it under a microscope and know that each station is just trying to do what’s right for their market, and it’s scary for a radio station to add a song that they don’t know how well it’s gonna do for them.


My music taste has changed and I listened less and less to radio, because we have now our iPods and mp3 players with us, even our phones have music players. Have I been unfair to radio that my course has something to do, now perhaps the only one in the Philippines to wave the flag for alternative music? I rarely listen to commercial radio, and when I do, I’m shocked by how many ads there are, and how annoying they are, and how bad the radio station usually is.

But not JAM 88.3 because it’s not a typical radio station we get to listen to.



All I wanted to do when I was a kid was getting dropped off at a radio station – one of the ones I listened to – and watch how the shows worked. And now I really can’t believe that I was able to visit one radio station that plays good music, and that’s something.



DJ Russ Davis

At first glance, Russ looks mysterious and a bit devilish, but there’s more to him than his mischievous smile. He also knows the local independent music scene like the back of his hand. A date with him means seeing some of the country’s best obscure bands in under-the-radar bars and venues. What happens after? Let his smile take care of the rest.

Fresh Filter is on every Monday to Thursday at exactly 3-6 PM. It is quite simply the only radio program that features nothing but local independent music. With new songs premiering every week, special guests and live performances. Fresh Filter is his segment on JAM 88.3 that prides itself on being finely attuned to the independent music scene, featuring various genres and the latest local talent.




Radio Microphone


A wireless microphone is a microphone without a physical cable connecting it directly to the sound recording or amplifying equipment with which it is associated. Also known as a radio microphone, it has a small, battery-powered radio transmitter in the microphone body, which transmits the audio signal from the microphone by radio waves to a nearby receiver unit, which recovers the audio. The other audio equipment is connected to the receiver unit by cable. Wireless microphones are widely used in the entertainment industry, television broadcasting, and public speaking to allow public speakers, interviewers, performers, and entertainers to move about freely while using a microphone to amplify their voices.

There are many different standards, frequencies and transmission technologies used to replace the microphone’s cable connection and make it into a wireless microphone. They can transmit, for example, in radio waves using UHF or VHF frequencies, FM, AM, or various digital modulation schemes. Some low-cost (or specialist) models use infrared light. Infrared microphones require a direct line of sight between the microphone and the receiver, while costlier radio frequency models do not.

Some models operate on a single fixed frequency, but the more advanced models operate on a user selectable frequency to avoid interference and allow the use of several microphones at the same time.



Electronic Mixer


An electronic mixer is a device that combines two or more electronic signals into one composite output signal. There are two basic types of mixer. Additive mixers add two signals together, and are used for such applications as audio mixing. Multiplying mixers multiply the signals together, and produce an output containing both original signals, and new signals that have the sum and difference of the frequency of the original signals.

These days beatmatching and beatmixing are considered basic techniques among DJ’s in electronic dance music genres, and its standard practice in clubs to keep the constant beat through the night, even if DJs change in the middle.

Pitch and tempo – The pitch and tempo of a track are normally linked together: spin a disc 5% faster and both pitch and tempo will be 5% higher. However, some modern DJ software can change pitch and tempo independently using time-stretching and pitch-shifting, allowing harmonic mixing. This technique is referred to as beatmatching.

Radio Imaging – Beatmix or beatmixing however should not be confused with another term used in radio imaging. Radio imaging refers to any produced audio material sung or voice over used to identify a radio station.


When I was on JAM 88.3, I used to be able to talk and ask a lot of questions to Dj Russ Davis. Now, you don’t really remember the feeling of talking and asking questions and hearing the music played along the booth live, not until you’re on the radio again. I strongly encourage listening to the radio to hear something you haven’t heard before. It’s a very healthy thing to do. It’s strange: unless you reload your iPods every couple of weeks, you’re listening to and recycling the same music all of the time. I’m serious. Listen to your radio station.
