== Introduction ==

[http://www.echolink.org/ Echolink] is a [http://en.wikipedia.org/wiki/Voice_over_IP/ VOIP] (Voice Over IP) application that allows amateurs to connect to one another using the internet. It is similar to [[IRLP]], but allows users to connect via either radio or computer. Application versions are available for [http://www.echolink.org/register_data.jsp/ PC] and [http://echomac.sourceforge.net/ Mac] computers. Echolink is not usually described as a digital mode - although VOIP is digital transmission of voice - as most operators will use an FM radio to connect to the echolink network.

VOIP connections of any sort - including Echolink - require a [http://en.wikipedia.org/wiki/DSL/ DSL] connection to the internet. A minimum connection speed of 256KBs is usually recommended for effective, clear VOIP applications.

== Using Echolink on a computer ==

As Echolink is an uses internet protocols for transmission of voice, various ports must be open in your firewall for it to operate properly, the Echolink website summarising the requirements thus:
* Allow UDP destination ports 5198-5199 between Internet and PC in both directions
* Allow TCP (source port any, destination port 5200) from PC to Internet

Because the firewalls only allow port directs to particular IP addresses - and hence computers - Echolink can in most cases only be used on one computer at a time in a particular household. Some ISP's may allow multiple unique external IP addresses, in which case echolink can be used on multiple computers.

The Echolink application presents a window such as the one below to the user.

The user selects a contact from the list and communication is carried out using the computer microphone.

== Using Echolink via a radio ==

'''Step by step process'''

* Look [http://www.echolink.org/links.asp here] to find out which nodes are available and where they are located. This list is updated regularly, and gives information about which nodes are connected to each other. If you use [http://earth.google.com/ Google Earth], this [http://www.echolink.org/node_location.kmz kmz file] will show you the connections between Echolink nodes.

* Locate a node close to you and one that you would like to contact. Repeater listings such as [http://ham.longlandclan.yi.org/ this one] for Australia, will provide useful information in your search.

* Use a DTMF microphone and dial in the node number that you wish to contact. A message will tell you if you either are successful or unsuccessful.

* There will be a delay between sending and receiving when using Echolink or [[IRLP]]. Best protocol is to wait a couple of seconds between hearing the other person and starting to talk yourself.

* When you have finished talking, use the DTMF buttons and dial in 73. This will disconnect the nodes.

===== [[|EchoLink DTMF Functions]] =====

EchoLink can be configured to accept commands through the local radio receiver using DTMF tones (TouchTones). These commands are used to enable or disable the link, or to connect or disconnect a station on the Internet.

Each command consists of a sequence of digits (or the special keys *, #, and A through D). Although a set of default sequences is assigned to each function, any sequence can be customized using the DTMF tab of the [http://www.echolink.org/Help/sysop.htm#dtmf Sysop Settings] page.

The table below lists each of the DTMF commands.

//Note:// If you have upgraded from an earlier version of EchoLink, you may need to choose “Reset to Defaults” to make all of the following commands available.

Connect

The default for the Connect command is to simply enter the 4- 5-, or 6-digit node number to which you wish to connect. To prevent interference with other DTMF functions, however, you may wish to configure a special prefix, such as A or 99.

Link Up and Link Down

No defaults are provided for these functions. To enable these functions, enter a DTMF sequence for each one, using the DTMF tab of the Sysop Settings page.

Profile Select

Profiles are numbered from 0 to one less than the number of profiles shown under File→Profiles. Profile 0 is always MAIN.

Station Shortcuts

Custom DTMF commands can be created to connect to specific stations. These commands are called Station Shortcuts, and are not shown in the table above. To manage your Station Shortcuts, click the Station Shortcuts button on the DTMF tab of Sysop Settings.

Entering Node Numbers

To enter a node number (for the Connect or Query by Node commands), enter the 4-, 5-, or 6-digit node number. If the specified node is not among the stations currently logged on, EchoLink will say “NOT FOUND”.

Entering Callsigns

To enter a callsign (for the Connect by Call or Query by Call commands), press two digits for each letter and number in the callsign. The first digit is the key on which the letter appears (using 1 for Q and Z), and the second digit is 1, 2, or 3, to indicate which letter is being entered. To enter a digit, press the digit followed by 0. When finished, end with the pound key (#).

For example, the letter “K” is entered as “52”, the letter “Q” is entered as “11”, and the digit “7” is entered as “70”.
<div class="table sectionedit2">
{| class="inline" border="3"
|- class="row0"
| class="col0 rightalign" | '''1''' Q-11 Z-12
| class="col1 rightalign" | '''2''' A-21 B-22 C-23 
| class="col2 rightalign" | '''3''' D-31 E-32 F-33
| class="col3 centeralign" | '''A'''
|- class="row1"
| class="col0 rightalign" | '''4''' G-41 H-42 I-43
| class="col1 rightalign" | '''5''' J-51 K-52 L-53
| class="col2 rightalign" | '''6''' M-61 N-62 O-63 
| class="col3 centeralign" | '''B'''
|- class="row2"
| class="col0 rightalign" | '''7''' P-71 R-72 S-73
| class="col1 rightalign" | '''8''' T-81 U-82 V-83
| class="col2 rightalign" | '''9''' W-91 X-92 Y-93
| class="col3 centeralign" | '''C''' 
|- class="row3"
| class="col0 centeralign" | '''*'''
| class="col1 centeralign" | '''0'''
| class="col2 centeralign" | '''#'''
| class="col3 centeralign" | '''D'''
|}
</div>
Callsigns need not be entered in full. If a partial callsign is entered, EchoLink will find the first match among the stations currently logged on. If no match is found among the stations currently logged on, EchoLink will say “NOT FOUND”.

Examples

(These examples assume that the default DTMF codes are configured.)
<pre> * To connect to node number 9999:
* Enter: 9 9 9 9</pre>
EchoLink responds with:

“CONNECTING TO CONFERENCE E-C-H-O-T-E-S-T”

followed by

“CONNECTED”

because 9999 is the node number of conference server ”*ECHOTEST*”.
<pre> * To get the status of K1RFD:</pre>
Enter: 0 7 5 2 1 0 7 2 3 3 3 1 #

EchoLink responds with:

“K-1-R-F-D 1-3-6-4-4 BUSY”

because 13644 is the node number of station K1RFD, and K1RFD is currently busy.
<pre> * To connect to a random link or repeater:</pre>
Enter: 0 1

EchoLink responds with:

“CONNECTING TO K-1-O-F REPEATER”

followed by

“CONNECTED”

because K1OF-R was selected at random.

== What's the actual license? ==

The current edit box states that "you are also promising us that you wrote this yourself, or copied it from a public domain or similar free resource (see Project:Copyrights for details)". I just created the "Copyright" page myself just now to try to document a bit what's going on here, but it would be important to clarify what the license is for the documentation here. I would think "public domain" would be appropriate, but there isn't such a notion legally all over the world. For the record, Wikipedia english states the following: "You irrevocably agree to release your contributions under the CC-BY-SA 3.0 License and the GFDL. You agree that a hyperlink or URL is sufficient attribution under the Creative Commons license." I consider my contributions so far to be public domain, but I would be happy to comply with CC-BY-SA or the GFDL. --[[User:TheAnarcat|TheAnarcat]] 18:22, 2 October 2010 (CDT)
