Time for quick tune up as radio stations alter frequencies

Time for quick tune up as radio stations alter frequencies

Starting from Sunday, radio listeners will have to make
adjustments when tuning into their favorite FM station, as the
stations are changing radio frequency.

The frequency shift complies with Directorate General of Post
and Telecommunications Decree No. 15A/2004 on the reorganization
of the country's radio frequency bandwidth usage. FM radio
stations operate in the band between 87.50 megahertz (MHz) and
108.00 MHz.

According to the new bandwidth allocation, the minimum
separation between FM radio station frequencies will now change
from the current 350 kilohertz (kHz) to 800 kHz, except in
Jakarta, Bandung, Semarang, Yogyakarta, Surabaya and Medan.

There are already too many radio stations operating in the six
cities, so only they are being allowed to maintain a minimum
difference of 400 kHz for a period of 10 years, before finally
being adjusted again.

The regulation is to prevent radio stations operating in the
same or too close a frequency, to avoid interference between
them, thereby resulting in broader transmission bandwidth and
better reception. The new regulation will also be useful in
anticipating future digital radio technology.

The nationwide bandwidth rearrangement was originally intended
to be effective from May, but radio stations were given a grace
period to Aug. 1 due to the technical problems they faced.

The Indonesian Association of Private National Broadcast Radio
Stations (PRSSNI) has welcomed the regulation, saying that, in
the past three years, 92 percent of 830 FM radio stations
countrywide have altered their frequency.

Some radio listeners, however, have complained that during the
transition period, reception of their favorite radio stations has
been poor and they have been confused about the channel changes.
