RATS has implemented Internet Radio Linking Protocol onthe W4RAT VHF repeater! Now, you can talk to repeaters all over the world any time you can access the 146.88 repeater. Open to all Amateur Radio Operators with a Technician or higher class license, you can now expand your ham radio horizons with this service. RATS encourages all hams that can access the repeaters to give this new mode a try!
IRLP is a method of using Voice Over IP to connect repeaters seamlessly throughout the world. You can connect point-to-point, or use reflectors to connect multiple repeaters together for nets or other uses.
Using IRLP is easy. You need a radio with a DTMF (TouchTone®) pad, and a node number to connect to. Node numbers can be found by going to the IRLP Project page on the web at http://irlp.net, then clicking on the “NODE INFO” link in the left menu, then on the “Connected Nodes and Reflector status” or the “List of nodes and Frequencies” links in the center of that page. Once you’ve found a node to connect to, the procedure is as follows:
And repeating: A two second PAUSE is necessary between each transmission, and a one second PAUSE is necessary after you key your mic, BEFORE you speak. If you do not pause, the other end will lose the first few seconds of your transmission, which is usually your callsign!
The Technical Committee can answer any questions you may have about IRLP usage. Please e-mail the RATS Technical Committee , we’ll try our best to help!
Our thanks to Ron McMurdy WA0OJS and Ralph Stoffel N3KZS, for their invaluable assistance in getting this new service for hams on the air. The installation was completed on September 15, 2006, and the RATS IRLP team trained with Ron and Ralph on Saturday, Sept. 16th.
