Mystery Signals from Arabian Sea Baffle Ham Radio Buffs:

eHam.net News — Mumbai: Amateur radio operators, also known as ham radio buffs, in Mumbai were baffled by unidentified mystery signal transmissions reportedly originating from the Arabian Sea on the country’s west coast, an operator said here on Monday. Though the signals have been picked up by their VHF wireless radios since the past five months or so, they became suspicious after they tracked them down to the deep sea off Maharashtra-Gujarat coasts, said Ham Radio Operators Mumbai spokesperson Ankur Puranik. “We have written to the Wireless Advisor, Ministry of Telecommunications and IT, with copies to the PMO, other ministries, and top defence and police officials to take note and investigate these unknown signals,” Puranik told IANS. They sent the memorandum to the Centre after analysing the signals with their direction-finding equipment and antennae and were alarmed to learn they originated around 100 nautical miles in the high seas off the Maharashtra-Gujarat coast. “They are encroaching on our allotted bandwidth 144-146MHz for our two-way radio, they don’t use the compulsory ‘call sign’ by which each ham radio operator in the world can be identified and tracked, and they speak in a language we can’t understand,” Puranik explained. The amateur radio operators did not rule out the wireless signals originating from some anti-social elements or sea pirates or other groups with possible nefarious motives.
