Chennai hams have now managed to go wi-fi/Hi-Tech with an Echolink connectivity via VU2 PUM-R link on the web . The node number is 492650.
Echolink was developed by HAM Jonathan Taylor K1RFD and is a computer based Amateur Radio system that allows radio amateurs to communicate with one another using Voice over IP (VoIP) technology on the Internet for at least part of the path between them. The system allows reliable worldwide connections to be made between radio amateurs, greatly enhancing Amateur Radio's communications capabilities.
Even though the interface looks simple it has taken nearly a month time to get the link become smooth and transparent. Thanks to all the stations for the excellent on the air support. The objective is to develop more user friendly options for the RF users like Time, weather etc on the air with simple DTMF code access.
