The Papakura Radio
Club operates an EchoLink conference server, *ZL1VK* (node 65001). The
Papakura Radio Club recognises the benefit for a New Zealand EchoLink conference
server for the use of all amateurs and clubs in New Zealand. This server
can be used to link computers, simplex radio links and repeater for running
local, nation wide or international nets. It is available for both open
nets or private nets. As an example the type of nets that could be run
on the conference server are … NZART, AREC, WARO, Branch Nets, etc...
For local New Zealand users on a slow dial up internet connection
the conference server can be used to speak to a number of stations in a
group which would not be possible without a fast internet connection.
Background
EchoLink is a voice over IP system that allows amateur radio operators
(only) to talk over the Internet. Users may be at a computer or using a
radio link or linked repeater.

Server Info
The *ZL1VK* conference server runs on a computer at a local club
members residence with a excellent high-speed network connections. The
conference is always up, except for occasional maintenance.
The conference server software is called the Bridge, and it comes
from the CQiNet family of free, open source programs for voice over IP.
To send a command to the server, you just type it into the message
line in your EchoLink window. The very first character you type must be
a period (.) -- that's how the server recognizes that it's a command. The
following commands are available to users:
.help
The server responds with a list of available commands.
.about <callsign>
The server responds with the info provided by the specified station.
This is the same info you'd see in the info window if you were directly
connected to that station.
.list
The server responds with a list of recorded audio files you can
play back using the .play command.
.play <item number>
The server plays back the recorded item you specified, including
both audio and text messages. While the item is playing, you are effectively
disconnected from the conference: you won't hear live audio or see live
text messages, and other users won't see you on the station list. To stop
playback, you can use the .stop command, or just disconnect from the server.
.lurk
Removes you from the visible list of stations, without disconnecting
you from the conference. This is useful if you just want to listen and
not be included in the conversation. You can still transmit if you want,
and if you do you'll automatically be added back to the list of stations.
You can also get back on the list by using the .delurk command.
.test
The server responds with an acknowledgement and then records your
next audio transmission and plays it back to you. Other users don't hear
it. Use this to test your audio set-up. Wait for the acknowledgement! If
you don't get the acknowledgement, the server isn't in .test mode and your
transmission will go out to the other users.
.stats, .uptime, and .version
The server responds with the corresponding technical data about
the operation of the conference server.
Scheduled Nets
If you run a local NZ-related net, and you have the consent of the
net manager and the repeater operator, and you want to expand your coverage
to the rest of the world, you may link your net into the *ZL1VK* conference
server. Before you do, please send email to zl1vk@nzart.org.nz with all
the details, so your net can be listed here. (See also the list of *ZL1VK*
nets on the radio.) The net controller will be given the sysop password
for the *ZL1VK* server with the addition commands and privileges to effectively
run the net.
If you're interested in establishing a new net exclusively for users
of the *ZL1VK* conference server, send email to zl1vk@nzart.org.nz.
Announcement / Recorded Information
The *ZL1VK* conference server has the ability to store bulletins
available for playback using the .play command. If you have information
that may be of use for calling in stations please send your recordings
to zl1vk@nzart.org.nz
Operating Guidelines
Usual operating practice on EchoLink is to operate just as if you
were on amateur radio. If any link station (callsign-L) or repeater station
(callsign-R) are connected to the conference, you are on the radio. Be
aware that other users may be anywhere in the world. Please use common
sense and courtesy.
Specifically, pretend you are on a busy repeater. That means:
? Identify with your callsign now and then. You don't need to ID
every transmission.
? Leave a pause of a few seconds between transmissions. This gives
others a chance to break in. It also lets linked radios and repeaters drop
out, so they don't time out.
? If several people are active in the conversation, consider turning
it over to one specific station at the end of each transmission. Don't
consider this mandatory, though. If there is a logical next person to speak,
let that person speak. If not, then a simple rule is to rotate speakers
in a fixed order. (The on-screen station list makes this easy. It is kept
sorted with the most recent speakers on top. So just turn it over to the
station on the bottom, or the lowest station who is actively participating.)
If you want to have a long conversation with one other station, and
the subject is not going to be interesting to others, consider dropping
out of the conference and connecting directly. If you talk about something
interesting, please stay on the conference!
