IRLP - Internet Radio Linking Project
146.775- (88.5 PL) Raleigh Node 4260 (reflector)
441.725 + (100.0 PL) UHF Hub Node 4270 (point-to-point)

IRLP stands for the Internet Radio Linking Project. The KD4RAA Repeater Group sponsored- KD4RAA 146.775 and K4JDR 441.725 repeaters are now linked to hundreds of participating repeater nodes throughout the United States, Canada, and internationally. We are the first in North Carolina to have a linking node into the IRLP project. 

The IRLP uses Voice-Over-IP software and the power of the Internet to link your radio site to the world. The system has its own custom interface board and software -- the interface board handles the DTMF encode/decode, PTT and carrier squelch to the local link radio that "talks" to the local repeater. In turn the local CTCSS encoded link radio hears your signal from the repeater and samples your message into the internet at our node control station.  

We're glad that so many people have discovered the IRLP. We have received many inquiries about using the IRLP and are pleased local hams we have never heard before are checking out the new system.  We encourage the use of this new method of global repeater linking system, but IRLP requires a little different operating procedure.  Before operating on IRLP, please read through the KD4RAA Repeater Group Node User Guidelines. 

. 

Please remember to leave a two second pause before you key to allow control operators to sign on and bring down their individual nodes and to give time for internet delays, and then to pause two seconds after you key up to give time for the global connections to come up. Also make sure you have a good signal, not only so people can copy what you're saying but so you can ensure that you are able to close any connection that you've brought up.

User Access:

  • The 146.775 repeater (Node #4260) is dedicated to continuous IRLP reflector connections, so any ham can tune in almost anytime and work DX.  You are welcome to jump in and join a conversation or start one yourself. If you don't hear the courtesy tone on 146.775, the node has been disconnected overnight while unattended or for maintenance or service upgrades.  Please do not kerchunk or key up without speaking -- this causes major problems with all of the other nodes connected to the reflector. Because the system has global coverage, please avoid local ragchews on 146.775.  Remember: anything you do on an IRLP reflector can be heard on the participating linked repeaters around the world.
