General Topics
What can I do with EchoLink?
EchoLink allows licensed Amateur Radio stations to connect to one
another over the Internet. You can use EchoLink to connect your station
(or your computer) over the Internet to other amateurs using the same software,
and carry on a voice QSO. This greatly enhances the range and utility of
mobile and portable VHF/UHF-FM stations, and also allows computer-equipped hams
to access distant repeaters directly.
You can access EchoLink either with a radio or a computer. If
you are in range of an FM repeater or simplex station equipped with EchoLink,
you can use DTMF commands from your radio to access the EchoLink network.
If you are a licensed amateur with an Internet-connected PC, you can access
EchoLink stations directly from your PC.
How do I get started using it?
First, download the software from this Web
site.
Then, install the software on your PC, be sure you have a good
Internet connection, and start it up to register your
copy of the software. The final step is to provide proof of license so
your callsign can be added to the system; see Validation
for details. Then, you're ready to go.
Is EchoLink a digital mode?
No. EchoLink is an extension of conventional voice modes,
particularly FM. EchoLink communicates over the Internet digitally, but does
not transmit any digital signals over the air.
Is EchoLink an Internet "chat room"?
Definitely not. EchoLink is a system designed to provide VoIP
gateways for repeaters and simplex stations. If you are interested in talking
(by voice) with other Internet users from your computer, or you would like to
participate in or set up your own Internet chat room, please use one of the
many excellent software packages designed for this purpose, such as
Skype.
Is there a separate "sysop" version of the
software?
There is only one version of EchoLink, which can be operated either
in "user mode" or "sysop mode". Switching to Sysop mode enables all of
the features needed for connecting a transceiver to EchoLink using your
computer's sound card and one of the popular interface boards offered by
WB2REM, W5TXR, or West Mountain Radio. For more information, see
Interfaces.
How does EchoLink handle security?
Each new user of EchoLink must be validated, which means providing
positive proof of identity and license, before being granted access. See
the Validation FAQ for details.
After having been validated, each EchoLink user must provide a
password, along with his or her callsign, to log in. Each time a
connection is made for a QSO, the EchoLink servers verify both the sender and
the receiver before communication can begin.
In addition, if you wish, you can configure EchoLink to accept
connections only from certain types of stations: repeaters, links, users, or
all three. You can also set up a list of any number of "banned"
callsigns, which will not be allowed access. In addition, you can block
or accept connections according to their international callsign prefix, in
order to comply with your country's rules regarding reciprocal control-operator
privileges or third-party traffic restrictions.
In Sysop mode, by default, EchoLink announces each station by
callsign when the station connects. The EchoLink software automatically
generates detailed logs and (optionally) digital recordings of all activity on
the link.
What is the difference between EchoLink
and IRLP?
EchoLink and IRLP are two separate systems that acheive a common purpose: Interconnecting Amateur stations by voice over the Internet.
The IRLP system consists of RF gateways (called nodes) and reflectors. Each node is either a simplex link or a link to a repeater (like an EchoLink Sysop node); there is no direct access from a PC. Each node supports only one connection at a time, but numerous reflectors are available (like EchoLink conference servers) to support roundtables and nets.
IRLP node owners purchase and install a custom interface board that comes with a special edition of the Linux software package on which the IRLP software runs. Each node has a 4-digit number, and one node can be linked to another using DTMF codes, similar to EchoLink. IRLP nodes can be customized by writing Linux shell scripts.
If you (or your club) are interested in setting up an RF gateway for both EchoLink and IRLP, a good choice might be EchoIRLP. EchoIRLP is a software package that can be added on to an existing IRLP node to allow it to connect to the EchoLink network. The result is a node that can connect (or receive connections) on either EchoLink or IRLP, using a single set of equipment.
What about remote control?
For enhanced remote control, EchoLink includes a built-in,
password-protected Web server which can be set up to accept commands from any
Internet-connected computer. Basic functions allow you to remotely enable
or disable the link, disconnect stations, and see who is currently using
it. The software also supports a basic and extended set of DTMF commands
for control over a radio link. For example, you can key in either the
node number or the callsign of the station you wish to connect to.
EchoLink also supports full DTMF remote control over a dial-up telephone line,
if a dedicated line is available. Is
EchoLink available for any platform other than Windows?
EchoLink is designed specifically to run under Microsoft
Windows. Currently, there are no plans to offer versions of EchoLink for
other platforms (except as noted below).
However, if you are running a Macintosh with OS X, you can use the
program EchoHam from the Mac App Store, which is compatible with EchoLink. (Support for EchoHam is not
available through the EchoLink Web site.)
Many users have also had success running EchoLink under Linux using the
Wine compatibility layer. For example, EchoLink is known to work with Fedora Core 5
and above, with a few limitations. However, Linux is not an officially supported platform for EchoLink.
Is
EchoLink available for smartphones and tables, such as an iPhone or an Android phone?
Yes! An edition of EchoLink for the Apple iPhone and iPad is available, free of charge, at the App Store.
For Android devices, please install EchoLink from Google Play.
Can I use EchoLink to set up a private link
system?
EchoLink is offered free of charge to the worldwide Amateur Radio
community for the purpose of setting up simplex and repeater links that can
be accessed by other EchoLink users. Although there are security
features that allow you to limit access to your node, the software (and the
system in general) is not intended to be used to create closed or private
systems.
How do you make any money on this?
We don't.
Do you accept contributions or donations?
Fortunately, because of the generous contributions of time and talent
by volunteers, the only ongoing expenses are Internet bandwidth and occasional
hardware and software maintenance. This is currently funded by the
Vanity Node Number program. Please consider participating in this
program if you wish to support EchoLink financially.
