Since most modern rigs have 100+ memories, some operators program in all the USA VHF/UHF repeater pairs and simplex channels.  For a list of these see URL:

Chapter 12, add D-Star Description


Some ICOM radios are coming out with the D-STAR system, In D-Star, the air link portion of the protocol applies to signals traveling between radios or between a radio and a repeater. D-STAR radios can talk directly to each other without any intermediate equipment or through a repeater using D-STAR voice or data transceivers. The gateway portion of the protocol applies to the digital interface between D-STAR repeaters. D-STAR also specifies how a voice signal is converted to and from streams of digital data, a function called a codec. D-STAR codec is known as AMBE® (Advanced Multi-Band Excitation) and the voice signal is transmitted in the D-STAR system at 3600 bits/second (3.6 kbps). For more info on D-Star, see URL’s:

And a D-Star System Map is shown at URL:

Glossary, Page G-2. Under Brick, change "linear" to "power", as most VHF/UHF amplifiers for FM are run Class C for efficiency.

Chapter 12, add WIRES II (Wide-Coverage Internet Repeater Enhancement System) From The Yaesu Site: HRI-100 URL:  

  WIRES-II uses DTMF signaling to establish a bridge, using the Internet, from your repeater or home station to another WIRES-II-equipped station anywhere in the world. At the repeater site, a personal computer is connected to the HRI-100 WIRES-II Interface Box, which serves as a command and audio-patching controller for the Internet bridge to your computer. Either a dial-up connection, or a high-speed line such as a DSL or ISDN line, may be used for connecting to the Internet. The flexibility of the WIRES-II concept allows you to configure the system to allow on-the-fly selection of linked or non-linked communications.

For fast-moving emergency communications where both local coordination and longer-distance reporting are required, WIRES-II allows local communications to be interspersed between linked transmissions. And because WIRES-II uses voice-recording technology as a buffer, WIRES-II calls will never interrupt a conversation in progress on a distant repeater. WIRES-II provides two operating network concepts.

Up to ten repeaters and/or home stations may join together to form a "Sister Radio Group" for closed-network operations, ideal for emergency, school, or sister-city groups. You can call any repeater within your SRG group using a single DTMF digit. And the host WIRES-II server also maintains a world-wide listing of repeaters operating in the "FRG" mode ("Friends' Radio Group"), any of whom you may call using a six-digit DTMF string to establish a link.  More on WIRES II  at URL:
