Ham Radio connect with the satellite

 

Each year, during the ham radio class, we escort the students into the field to provide them with firsthand experience of radio operations. This year, as customary, we brought them to the VU2OW Ham Station. Mr. Rajesh (VU2OW) warmly greeted us, emphasizing the importance of approaching with love whenever we reach out. Despite my last-minute request, he graciously welcomed us with the same affection.

Distinguished from other ham stations, VU2OW boasts the unique capability to both receive and transmit all satellite broadcasts, including DMR, using a valve radio box at a single location. The hospitality extended by Mr. Rajesh's family during our visits never fails to amplify the students' enthusiasm.

Mr. Rajesh, an avid homebrew enthusiast, mentioned his ongoing experiments during this visit. Of particular note was a finely crafted key port by his son, designed to endure substantial pressure. The array of antennas adorning the attic of his residence is remarkable, with more than ten antennas often observed in one location. Undoubtedly, today's visit has left an indelible impression on the students, providing them with a memorable experience.

Book on Ham Radio

The second Tamil book on Ham Radio series will be released on the "Public Service Broadcasting Day (Nov 12)" in the All India Radio, Chennai at 13 Nov 2017, 4.30 pm.

In Chennai where communications are cut off, ham radio operators chip in

Ham radio operators have swung into action in flood-hit Chennai where communication network at several places was affected. In addition to Hams who have surfaced, having been caught in the flood waters themselves, to provide the required communication to carry out relief works, many more hams from across the country are ready to travel to Chennai.

Five hams from Hyderabad, 10 from West Bengal, eight from Kerala and some from Coimbatore are coordinating with the National Institute of Amateur Radio (NIAR) in Hyderabad.

"Everyone is ready to render their services. Many more are volunteering. The Tamil Nadu government should have a monitoring agency to fully utilize the services of hams. If the government is willing to do that, many hams from different parts of the country are eager to go to Chennai," S Rammohan, director of NIAR told TOI.

On Friday morning, Rammohan who goes by the call sign VU2MYH got in touch with hams in Chennai. "Hams there are networking among themselves and providing information for relief works to be taken up," he said.

For the first time in a major way, hams are not just sticking to providing information where other means of communication are not working, like telephones and mobiles, but also helping in relief works.

VU2DH has a shipping agency with branches in different parts of the country and his work would have kept him busy otherwise. But with the deluge in Chennai, Dev Das, got into the act to be of service to the public. "Water was flowing at 12 feet at the place where I am standing now. This has been the situation in the last three to four days. Today, the water has receded a bit and enabled us to come here," Dev Das told TOI from Chennai.

Dev Das was at a locality close to Jafferkhanpet, near the airport in Chennai. Another ham, VU2GMN, is also active providing communication network.

In all 20 hams are active in Chennai. "Sadly, we do not have government support. But we cannot keep quiet because we want to be of help to the people," Dev Das said. Not only did Dev Das cook food for 50 people at his residence to take to the flood affected people, he is also collecting food packets wherever they are available and distributing where necessary.

The 20 hams in Chennai have informally tied up themselves with someone from the National Disaster Response Force (NDRF). By SUSHIL RAO,

Reaching Out on Airways: AT8LH

Add HAM radio in school syllabus -By N.Arunkumar

Users of amateur radio, also known as, HAM radio, have urged the Centre and state to include their hobby in school syllabus. They say this would take the technology to youngsters and since amateur radio often turned out to be the only mode of communication during disasters, it would help the HAM community to reach out more. In the west 70 to 80 persons in a population of one lakh used HAM radios but in India only one,in 20 lakh people used them, said Inarapan of Kalpakkam, who has been using these radios since 1985.

"The investment needed for setting up a HAM radio is not huge. The cost of a basic model is as cheap as Rs. 500. Most of the people in India are unaware of the advantages in using HAM or they are misled by people who do not know about it. These are the main reasons for the low number of HAM users in India," he said.Some of the famous HAM radio users include late Prime Minister Rajiv Gandhi, UPA chairperson Sonia Gandhi, late minister for commerce and industry Murasoli Maran and actor Kamal Haasan. During the 1999 Orissa super cyclone and 2004 tsunami HAM radio was the only mode of communication used for coordinating rescue and relief measures.

Speaking to Deccan Chronicle on Sunday on the sidelines of the International Lighthouse and Lightships Week (ILLW), Ajoy, member of the Bangalore Amateur Radio Club said, "CBSE has added HAM as a lesson in disaster management subject for classes 8, 9 and 10. The state should also follow CBSE and include HAM in their syllabus."K Rajesh, another HAM user from Chennai said, "HAM is an excellent mode of communication for people across the world. This helps us to get in touch with persons from different countries, apart from developing our knowledge in electronics. "-Deccan Chronicle 18/8/2008
