At technocrat Ankur Puranik's office in Wadala East, he and his group of friends — all of whom happen to be ham/amateur radio operators — are discussing the muggy weather. Only here, it's not a conversation starter, but a subject that has kept them bonded for years. "The ham radio network works as a platform, where you meet like-minded people through a wireless radio transmitter and receiver. That's how we came together. Exchanging notes on weather conditions is one of the things that we do through it," says Puranik, chief technology officer at Om Energy Savers, a power-saving company. Now, the team is set to take their passion one step further.'
