Anytime this month, DZRK Radyo ng Bayan [1323 kHz] is expected to run uninterrupted and will now be covering a wider area after the installation of its brand new transmitter. The old transmitter, which is an ‘inheritance’ from an old US radio station in the country, had been causing several problems putting the station off-the-air several times for the past years.
Engineer Rico Tome, Senior Manager Engineer of the Composite Technology Equipment Harris explained that the new transmitter is more sophisticated and is electronically run unlike the old vacuum tube type, a design of the late 70’s radio stations. The new design is composed of different combiners, computers and amplifiers, which could operate the 10 kW output at full power.
“It’s possible that this transmitter could run for 10 years without any problems,” he said. He however noted some considerations needed to be rectified in the transmitter site to assure a smooth operation once it goes on-the air this June.
According to Tome, possible problems could be mainly on the mismatch of the amplifier to the antenna site power supply. He added that since the device is electronic, anything can happen. His recommendations include the need to install an AVR and Transient Voltage Suppression System (TVSS) to stabilize the voltage. This he said is a basic requirement for any electronic system.
“These devices will maintain the three phase 220 volts even if there will be fluctuation in the primary current source,” he said. When the station is operating in a full 10 kW output, Jose Rostigue Jr. Senior Operations Supervisor of DZRK, Radyo ng Bayan informed that the primary areas that the station could reach include Nueva Vizcaya, Cagayan, Ifugao, Apayao, Abra and some parts of the Ilocos Region.
