IRLP (Internet Radio Linking Project)Links repeaters over the internet. All traffic must start on RF.
Both full duplex and simplex repeaters.
Started in 1997 to link systems across Canada
Custom hardware. Software runs on Linux.
Currently almost 3,000 nodes. 1,772 active. 38 countries. (2,191 in the US)
Lots of info on www.irlp.netSlide5
Links, Repeaters, Reflectors
Link: Simplex
Repeater: The repeaters we all know, or maybe a more local one
Reflectors: Many links and repeaters connected togetherSlide6
Using IRLPCan connect to either a repeater (
xxxx
) or a reflector (9xxx). Many repeaters can connect to the same reflector.
Find a close repeater using your favorite repeater directory.
Make a call:
Listen for activity on the repeater
Identify yourself and the node you wish to call
DTMF: 4 digit node number (i.e. 3978 for K7LHW)
Listen for about 10 seconds (the repeater might already be in use.)
Be sure to wait 1-2 seconds after pushing PPT.“73” Disconnects.
Repeater owners can change the default commands. (0 gets status, usually)Slide7
EchoLinkStarted in 2002.
More than 200,000 validated users in 151 (of 196) countries.
3 Node types:
-R: Full Duplex Repeater
-L: Half duplex
(no suffix): Software
Basically the same features as IRLP with the addition of non-RF endpoints. (i.e. PC, Mac, and iPhone and Android.)
Requires a valid license to get an account.
Can also set up conference channels. (Great way to have topic specific reflectors.)
Lots of info on www.echolink.orgSlide8
Using
Echolink
There are two different ways
Use a repeater.
Basically the same as IRLP with longer node numbers.
Might use # to disconnect
Use a computer or smart phone
Install the software
Register and valid your license
Call using the softwareSlide9
Other VoIP SolutionsAnalog Modes:All-Star: Similar to
Echolink
functionality. Uses a more modern code, open HW.
WIRES-II:
Yeasu
proprietary mode. Really only used in Japan. <100 active nodes.
iLink
,
eQSO
, CQiNET (open source)Digital Modes:D-Star: Adds callsign routing, but be careful.Fusion: Better audio than D-Star
DMR: More open standard(?)Connecting them together?Slide10
Nano-NodeEcholink & IRLP client and radio in a small package
Almost completely plug & play.
Web interface.
$495
They also make
AllStar
& D-Star/DMR/Fusion/P25 solutions.Slide11
Big Problem: Static IP, Firewalls, and VPNsAll solutions require other users to send info to your IP address
Ways to solve this:
Software routing ala
Echolink
Static IP
Firewall DMZ
VPNSlide12
Other Portable Node Options
Micro-Node (maker of Nano-Node) makes the best plug & play options
Echolink
& IRLP – No other off the shelf units. Rolling your own is complicated.
