India's The Print reports Chandana Basu and Sabita Roy, two friends in Tripura who parted ways in 1981, were brought together again by the Tripura Ham Radio Club set up by police officer Biswajit Saha VU2LJB 

The newspaper says:

The two women grew up in the staff quarters for the Agartala airport personnel and attended the Bani Vidyapeeth School and later a women’s college in the city together. Basu’s father was, however, transferred to West Bengal in 1981 and the two were separated.

Basu, who now resides in West Bengal’s Barrackpore, recently got in touch with members of the Tripura Ham Radio Club and provided them with Roy’s Agartala address since she did not know her friend’s current location.

The club’s members then dug up information on who resided in the Agartala airport quarters around 1981 and was able to trace Roy to Udaipur, where she now lives with her family.

A video conference was subsequently arranged between the two friends by the Tripura Ham Radio Club and the Calcutta Ham Radio Club.
