  7. Alternate System You can also down load the software to your PC and chat with any EchoLink station from your PC.

  8. Find some node numbers

  9. Types of Connections: ZL1VK-R The “-R” means that you are connecting to a repeater at the other end. ZL1VK-L The “-L” means that you are connecting to a link, possibly a radio operating on a simplex frequency, at the other end. KC2APG No suffix means that you are connecting to a computer at the other end that does not connect to a radio.

  10. Commands (227963) Entering the node number directly connects you to that node. 08 Status is announced 09 Reconnect to last station 011 Connect to random favorite 02 Connect to random conference 03 Connect to random user (link) # Disconnect

  11. Demonstration • Tune our Radio to the 146.880 repeater • Listen for activity…… • On the TT pad, punch 01 (Random node) • The voice announces KA2TSC connected…….N2STC • You then announce {your call} listening, or call CQ • When someone answers, talk normally • When finished, hit # to drop the connection

  12. EchoLink Comments • Broadband or Dial-up Internet connections work. • Some consider computer-to-computer not “amateur radio.” • If you access the Internet through a router, you have to program the router to forward packets. At home this is OK. In big companies, a problem. • Some folks leave EchoLink software running on their computer even when they’re not around to answer calls. This isn’t polite. • There is sometimes a slight delay in the audio. It’s best to leave a longer pause on an Echolink repeater. • Callsign validation process not robust.
