8-27-2012 Voice over Internet Protocol WORC  Voice over Internet Protocol Nodes Operating The WORC EchoLink node  Node# 82962 EchoLink is an Internet based computer application which allows amateur radio operators around the world to make voice contacts using Voice over Internet Protocol ( VOIP ). The programming is flexible, allowing contacts from repeaters, simplex radios, or from your home computer. There is also provision for using EchoLink to connect to amateur radio operator discussion groups. There are four types of EchoLink stations : Conferences: A node available for multiple connections, hosting a roundtable type discussion. Users: An individual using their home computer to operate an EchoLink Node without using an RF system. Links: An individuals RF based EchoLink Node operating as a simplex connection. Repeaters: An RF based EchoLink Node connected to an Amateur Radio repeater. The EchoLink Node connected to the WORC repeater system is a Repeater node operated by Ron, KJ7IY. The node uses a Windows computer with a sound card and a sound card interface board to connect the Node to the WORC trunk through an RF link. The node is running continuously. Any of the repeaters connected to the WORC system can access the EchoLink Node when that repeater is connected to the WORC  trunk. The KJ7IY EchoLink repeater node can host up to 4 simultaneous connections from other EchoLink nodes. What you hear when you connect to the WORC EchoLink node is a linked repeater system with three to five repeaters normally interconnected. At various times of the day all of the WORC repeaters will be connected to the node for local nets. Please be aware that several nets are controlled nets for serious purposes and not just rag chewing. Follow the net protocol if you wish to participate. EchoLink systems which have courtesy tones, multiple ID's and announcements may be disruptive to our local nets and may be disconnected by the WORC control operators if needed. Several times each week the WORC participates in nets on the Evergreen Intertie. At these times there may be up to 48 repeaters connected to the WORC  EchoLink Node.  Information on EchoLink is available on the Internet : The information available on this site includes an active listing of EchoLink nodes. This listing would allow you to determine what nodes you might wish to connect with to contact friends, either old or new, all over the world. The web site also includes information about the program and tips on using it effectively. Visit this site to learn about the program and it will enhance your enjoyment of EchoLink. Using EchoLink for incoming traffic: It is very easy to use EchoLink for incoming traffic on the WORC system. When you hear a non local station identifying on the repeater you are listening to, just contact the station as you would a station operating on RF. No control codes are needed. Just grab your microphone and commence communicating around the world. Using EchoLink for outgoing traffic: Using EchoLink to connect to another node over RF is a little more complicated. You need the Node number of the EchoLink Node you will be connecting, then you enter the node number for the node you wish to connect. The node address for the other system is unique for each system you connect to. That is, if your friend can access node # 12345, then when you wish to speak to that friend, you enter the access code, then 12345. Entry of the access command and the desired node address is done with your radio DTMF key pad. The disconnect code is used to disconnect the other node at the end of a contact. To connect to the PE1OTP repeater ( Node # 27666 ) in the Netherlands, these commands would be used: Key your PTT switch, enter the DTMF commands, then release the PTT switch. You'll hear the announcement for the connection if your command is correct. When you have completed your contact with The Netherlands, enter the disconnect code: Key your PTT switch, enter the DTMF disconnect code then release the PTT switch. There is no disconnect message currently. Use the EchoLink interrogate command to hear the node status. It is that easy! Have fun. Operating The WORC IRLP node  Node# 3881 IRLP is another Internet based computer application which allows amateur radio operators around the world to make voice contacts using Voice over Internet Protocol ( VOIP ). The programming allows contacts between repeaters or Reflectors. Reflectors allow multiple repeaters to connect to a single point, making contacts between multiple repeater systems at one time. The IRLP Node connected to the WORC repeater system is operated by Ron, KJ7IY. The node uses a Windows computer with a sound card and a sound card interface board to connect the Node to the WORC trunk through an RF link. The node is running continuously. Any of the repeaters connected to the WORC system can access the IRLP Node when that repeater is connected to the WORC trunk. Information on IRLP is available on the Internet : The URL for the IRLP web site is http://www.irlp.net The URL for IRLP Reflector status is  http://irlp.g4eid.co.uk/status/all_reflectors.html Using IRLP for outgoing traffic: Using IRLP to connect to another node over RF is a little more complicated. You need the Node number of the IRLP Node you will be connecting.Then you enter the node number for the node you wish to connect using DTMF tones. The node address for the other system is unique for each system you connect to. That is, if your friend can access node # 12345, then when you wish to speak to that friend, you enter the access code, then 12345. When you have completed your contact, enter the disconnect code.
