AllStar Link

A Global Amateur

Radio Community Prepared by : John Arto

What Alternatives Are There?

Echolink

Proprietary windows software

Cell phone Apps

IRLP (Internet Radio Linking Project)

Linux based

Closed source hardware and closed linking network

No EchoLink compatibility

AllStar Link

Linux based

Most open, most connectivity options

EchoLink compatible

Based on high quality audio switching technology (Asterisk)

Others app base

Third party apps which are not open license GPL/LGPL, e.g Zello, Teamspeak 3 etc

4

The EchoLink Node

My W7JCA-R EchoLink on 445.875MHz

PC running Windows and EchoLink software

Using Signalink USB interface

Motorola CDM1550 for link radio

Running windows version XP

5

The EchoLink Node Why change it?

Worked ok, but inflexible

Linked connections suffer from lag

Limited multi-conferencing

Limited in its ability to grow (no upgrades since 90s)

Based on proprietary Windows based software

One node per 1 IP address (need to use proxy if

wanted more)

Max 3 nodes per Callsign

6

The EchoLink Node

7

IRLP First radio over internet network protocol (ROIP)

Half-duplex

Node to node or node to reflector

Proprietary hardware needed to connect to radio

The AllStar Link network consists of a number of large (and small) individuals and groups who wish to provide efficient large-area communications to the Amateur Radio public in their respective local areas.

It is not perfect technology

Utilizes VoIP (Voice over Internet Protocol)

Repeater – Full Duplex

Simplex Node

Hub Node – No Radio Hardware

8

AllStar Link AllStarLink.org

What is AllStar Link?

Excellent Audio Quality (G.711µ-law)

Provides More Connectivity

Can link with any other AllStar Node or EchoLink (if enabled) node (repeaters or simplex nodes)

Individuals can uses the Web Transceiver. (no longer supported)

Any touchtone phone through the Telephone Portal

Android Smart Phones or Tablets with IAXRPT app (PTT)

Windows PC with IAX RPT app (PTT)

iPhone or Android with IAX Client app (you can use sip protocol too if you enable sip module (not recommended)

9


Why AllStar Link?

Automated announcements (Time, weather, meetings, etc)

Cheap to implement (only Rpi2-3, CM108 Soundfob and a Baofeng 888s)

It can be configured to do desired functions

Automatically link repeaters for nets, etc.

Weather Conditions, alerts and forecasts

Emergency operations modes (different courtesy tones, predefined linkages, emergency announcements)

10


Why AllStar Link? (cont.)

Implement new functions without having to visit the repeater site

Recording and archiving of all audio passing through the repeater

Remote control of node via the Internet (including but not limited to changing timeouts, PL, courtesy tones, enable, disable, DTMF functions, macros, etc) also can remote via allmon2 and supermon (web admin version)

Uses Linux operating system for stability (hamvoip rpi image)

11


Why AllStar Link? (cont.)

12

The AllStar Link Setup • Raspberry Pi 3, Node 48467 W7JCA

13

The AllStar Link Setup • Raspberry Pi 3 & URI

14

The AllStar Link Setup • Rasp Pi DMK interface

• http://www.dmkeng.com/Products.htm

http://www.dmkeng.com/Products.htm



15

Allstar Software Setup • Download Rasp Pi 2-3 image from

https://hamvoip.org/RPi2/RPi2-3_V1.5rc16_Allstar.exe

• Extract the img (image) file

• Download the Win32 DiskImager

http://sourceforge.net/projects/win32diskimager/

• Write the image into your micro SD card

• Connect your Ras Pi into monitor & keyboard, follow the

instruction. (The setup will be guided and with menu, after

setup, the keyboard and mouse will not be needed anymore)

• SSH into your Pi IP address with port 222 to configure if you

need any configuration

Connections to

Alternative Systems

ECHOLINK linked node

DSTAR linked node

WIRESX linked node

IRLP linked node

DMR linked node

25


AMBE3000 Dongle (GPIO)

To bridge to DSTAR/DMR

26


AMBE3000 USB version

to bridge to DSTAR/DMR

27


• To bridge from analog (allstar) to digital,

AMBE3000 type hardware needed to do

vocoding (transcoding)

• https://github.com/N4IRS/Analog_Bridge • Dummyrepeater for DSTAR

• There is a group that is discussing on the

development

• https://groups.io/g/DVSwitch • hb_link and hb_bridge to DMR

Real World Scenario

31


Allmon2 (simple webadmin for connect disconnect nodes)

32


Supermon (advance version webadmin for connect & disconnect

nodes and so much more, even restart the asterisk or server reboot)

33


UK HubNet, a large allstarlink HUB/nodes that linked all the nodes

together (41522, 41223, 41288, 43845) . Linked to DMR TG23526

Always know what your node is or is not linked to before connecting to another node

Never link two large systems together

When linking your node to a large system it is best to link to a HUB instead of a connected node

HUB nodes generally have a superior Internet connection and handle higher throughput

Administrators can readily troubleshoot and remedy any problems that may arise from a central point

Never daisy-chain nodes to a HUB

Never RF Link to a repeater you do not own without the owner's permission

39


Good Practices to Follow

Pause 2 seconds before speaking to allow all far end

transmitters to synchronize

Pause 2 seconds between transmissions to allow other

stations to break in

40


Good Practices to Follow (cont.)

A node assigned to you from AllStarLink.org

A Computer

Node radio or radios (simplex or full duplex)

An interface to connect your computer to your

node radio or radios (simplex or full duplex)

Broadband Internet connection
