Growing numbers of hams are using VoIP, or Voice Over Internet Protocol, in combination with their radios for long-distance communication spanning hundreds or thousands of miles. They're using the Internet as the relay between their base stations, handhelds and mobile transceivers.
This is a guide to the four primary VoIP systems used by hams: The EchoLink® System, IRLP, eQSO and WIRES-II. The book is designed for beginners who need information on how to set up and use these systems, but it also provides plenty of technical "meat" for those who want to dig deeper and explore how the systems actually work.
Author Jonathan Taylor, K1RFD is the creator of the EchoLink system and is one of the top experts in Amateur Radio Voice Over Internet Protocol.
