All along, i and some tech experts and bloggers believed that never a mobile phone could sport an AM (amplitude modulation)tuner inside it.
My vast knowledge on radio broadcasting and radio electronics support this general thought that whenever an AM radio tuner is placed near a cellphone… the radio set would sound static.
This is because, by its nature, amplitude modulation is susceptible to electronic noise pollution. Strike a spoon and a fork together near a radio set tuning the AM band and you will hear static sound.
So, how much more if you place an AM tuner inside a cellphone unit? It would sounds like suicide for the AM tuner.
I have heard about a cellphone in Europe having an AM tuner but the tuner is receiving digital signal from a digital AM broadcast. The Philippines is very far when it comes to digitalizing the AM broadcast. The television broadcasts in the country will all go digital by 2015.
But two weeks ago, our radio listeners told me about a cellphone from Sony Ericsson with an AM radio that have been promoted by Sun Cellular. I was caught flat-footed. I never knew about it.
The next day, i have read about it in the papers while i was taking my break at the USJR library. In the evening of same day, i was able to see the actual unit displayed at the lobby of the Waterfront Hotel as one of the sponsors of the opening nite of the weeklong Press Freedom Week Celebration.
To make this story short, i had able to possess a unit of the R300 radio and test it for the first few days prior to introducing it during the September 28, 2008 episode of “Hi-Tech ‘Ta Bai!”.
I have recommended the unit to those who loved AM broadcast. It would be very portable for us to bring one gadget instead of a cellphone and a radio monitor. This is more useful to radio reporters and journalists who always tune in to the AM broadcasts.Aside from the AM tuner, it has a good quality voice recorder which a reporter can use for interviews. However, it can’t record a call conversation. This feature is only available in the other cellphone radio model–R306 which is not available in the Philippines.
While i was mobiling at the mid-north of Cebu, i observed that DYAB1512 signal is static. This is true because of the high frequency assignment of DYAB at 1512khz. However, the rest of the stations at the lower frequency sound good. In Cebu City, DYAB is fine enough while i was also travelling across the city. The tuner is far better sensitive than the small radio monitor available in the market.
The R300 sports a bluetooth and can be switched to the FM radio tuner when you want music-on-the-go. It has also a VGA camera though it’s not that good in quality as the high-end cellphone camera.
Here are some of the important specs of the R300 radio:
- Dimension : 101 x 46 x12mm
- Weight : 75gm
- Colors : Antique Copper, Steel Black, White
- Screen : 65,536 colors TFT, 128 x 160 pixels
- Phone memory : 8mb
- Networks : GSM 850, 900, 1800, 1900
- Battery Performance : 9 hrs–talk time; 410 hrs–standby time
Here’s the catch–it’s only P4,499.
