    These are the VHF frequencies use in air traffic control in Sri Lanka
    118.700 BIA Tower
    121.900 Ground Operation -Katunayake
    119.100 Ratmalana Tower
    124.900 Colombo Radar - Having its centre at Ratmalana Airport premises. Antenna fixed at Piduruthalagala mountain
    132.400 Colombo Director – Operation centre at Katunayake
    As soon as an aircraft reaches (South East sector) approximately 200 NM (VHF communication is not capable beyond this range) Colombo radar hands it over to HF. This centre (Colombo Radio) and the Colombo radar (124.900 MHz) are sharing the same building at the Ratmalana airport premises.
    These are the main frequencies use in Colombo Radio
    11285/6556 (11.285MHz 6.556MHz) You can listen to this ratio by tuning these frequencies in your short wave radio. As these channels use (single side band) you need a BFO (Beat frequency oscillator) or a radio with SSB. However, in a short wave radio still you can listen without having SSB BFO facility but hard to understand clearly as it uses different modulation
    CPDLC – will be used as an alternative to HF (High Frequency) But some aircrafts doesn’t have this facility onboard. They rely on HF. Some prefer to use HF to cut their operational costs (CPDLC is a commercial service and need to pay)
    I admire your work and thankful to every one of you for attempts taken to take aviation another step closer to Sri Lankans.
