The incident first came into light in June after amateur Ham radio operators picked suspicious radio signals and unauthorised radio communications in coded Bengali and Urdu in Basirhat and Sunderbans region. Alarmed over the incident, the operators informed the Centre following which they were called to an international monitoring centre (radio) and asked to track the signals. A team of 23 Ham radio operators are now on round-the- clock duty trying to track the exact location of radio signals. Biswas said after the incident came into fore they had written to the Union ministry of communication and information technology, highlighting the strange signals and the suspicious mode of coded communication.
