Preferences
Preferences lets you customize several of EchoLink's features to suit
your own taste. Choose one of the tabs along the top to view the Listing,
Connections, Security, and Signals options. Each of these tabs is
described in detail below.
Listing Tab
Items on the Listing tab control options for the station list area at
the center of the EchoLink screen. This portion of the screen
shows the callsign and location of each station currently on the system,
and whether each is Busy (already in contact with another station) or On
(ready for a new contact).

Update station list automatically: If this box
is checked, the station list will refresh itself periodically. The
box below specifies the number of seconds between each refresh.
Even while connected: If this box is checked,
the automatic refresh will occur even while you are in contact with
another station. On slower Internet connections, this may
interfere with smooth performance of the audio, so you may wish to
un-check it. If the box is un-checked, EchoLink will refresh the
station list as soon as your contact is complete, unless less than 30
seconds has elapsed since the last refresh.
Show in Index View: This set of check boxes
specifies which types of stations you wish to include in the Index View.
Un-check any types of stations you do not wish to see. For
example, if Stations Free is checked but Stations Busy is not, any
station currently in contact with another will be omitted from the list.
Alarmed Only : If this box is checked, only those
stations which have been added to your Alarms list will be displayed.
For more information, see Tools Menu.
Show Alarms in pop-up window: If this box is
checked, the Alarm Log window will automatically open each time an
Alarmed station changes status, showing the station's callsign and
status. You can also open or close the Alarm Log window from the
View menu.
Add New QSOs to Favorites: If this box is
checked, EchoLink will automatically add any stations to which you
connect (or which connect to you) to your list of Favorites.
(Favorites is one of the folders in the Explorer View). This is a
convenient way of quickly re-connecting to a station you have spoken
with recently.
Restore window size and position on startup:
If this box is checked, EchoLink (on startup) will restore the main
program window to the size and position at which you left it when it was
last shut down. Otherwise, EchoLink always starts the program with
the default size and position.
Connections Tab
The Connections tab includes controls for setting up the Conferencing
features of EchoLink, and for setting text messages that appear during a
contact.

Allow conferences: Check this box if you wish
to allow more than one other station to connect to your EchoLink
software at a time. In the box beneath, enter the maximum number
of stations you wish to allow at once (not including yourself), to a
maximum of 60.
The conferencing feature is not recommended if your PC is connected
to the Internet over a slow link, such as a dial-up modem.
Update Location entry with status: If this box
is checked, EchoLink will automatically update your station's entry in
the Station List with a notation about the number of stations which
have joined the conference. This allows other stations (who have
not yet joined) to see the status of your conference. The notation
is a number, in parentheses, added to the end of your
Location/Description entry. Note that your station will be listed
as On (rather than Busy) as long as the maximum number of connected
stations has not yet been reached.
Send station list to all
stations: If this box is checked, EchoLink will
periodically update the text screen of each connected station with a
list of all stations in the conference, with an arrow indicating the
station that is currently speaking. This takes the place of the
Station Information file, if one had been configured. This list
will also appear on your own screen, even if this option is not
selected.
Location/Description: The text in these two
boxes will be displayed next your station's callsign in the Station List
that is viewable by all stations on the system. Different text may
be specified depending upon whether your station is Free (not in
conversation) or Busy. Normally, however, these two items are the
same.
Show name of connected
conference: When this box is checked, each time you
connect to a conference, EchoLink will automatically update your
Location listing with the name of the conference, instead of your usual
Location/Description. The listing (that other stations see) will
become "In Conference XXXXX", where XXXXX is the callsign of
the conference server or EchoLink conference you are connected to.
(Note that this information will not appear in your own Station
List until the next refresh.)
Space Bar TX Control:
Choose between two options for how the space bar behaves as a TX
control. When Tap On / Tap Off is selected (the default), tapping
the spacebar once will switch to TX, and tapping it again will switch
out. When Momentary is selected, press and hold the spacebar to
TX, and release it to stop, like a conventional push-to-talk switch.
Middle Mouse Button:
If you are using a three-button mouse (or a mouse with a clickable
wheel), check this option to use the middle mouse button as a TX
control as an alternative to the space bar.
Station Information File:
EchoLink sends a text message to the other station when you
establish a connection, which appears on the other station's screen.
By default, this message is "Station XYZ", where XYZ is your
callsign. Choose "Edit..." to make changes to this
message, or choose "Choose..." to select some other file
(besides info.txt) as your Station Information File.
If "Edit..." is grayed out (not available), it may mean
that the station information file has been deleted. If this
happens, use Windows Notepad to create a new one, then click
"Choose..." to locate it so it can be used by EchoLink.
Show Alert when "Doubling":
Normally, EchoLink does not allow two stations to transmit at the same
time. However, due to Internet latency, it is possible for two
stations to double if they begin transmitting at exactly the
same moment. Enable this option to display a warning message in
the Chat window if you are doubling with another station.
Security Tab
The Security tab controls features which prevent undesired access to
your EchoLink system. This is particularly of interest in the
Sysop mode, although the Security settings work in either mode.

Allow connections with: These four
checkboxes control which types of stations you are willing to connect
with. If a station that has been excluded tries to connect,
EchoLink will immediately deny access, and make a special notation in
the Log file.
Note: Un-checking "Conferences" will block
connections only with "conference servers", and
conferences running EchoLink version 1.1 or above.
If Conferences is un-checked, EchoLink will not allow connections
with conference servers or EchoLink conferences. It is possible,
however, to be connected with a station which later becomes a conference
(when it connects with a third station). In this case, EchoLink
will immediately disconnect, but only if Dynamic conf detect
is checked.
Deny these calls: Select this option to set
up a "banned list" of stations with which you do not want to
connect. Any number of callsigns may be entered. To add a
new callsign, choose Add New, then type the callsign (including any -L
or -R suffix) into the blank space provided. To remove a callsign,
select the callsign and choose Remove. Choose Remove All to clear
all callsigns from the list. If the list is empty, no connections
will be denied based on callsign.
Accept only these calls: Select this
option to set up an "approved list" of stations with
which you wish to allow connections exclusively. If this option is
selected, no connection will be established with a station whose
callsign is not listed. As with the Deny function, all callsigns
must be fully spelled out, including any -L or -R prefix.
Note: Instead of (or in addition to) callsigns, you can also
enter IP address ranges in this list, in CIDR notation. This is
sometimes useful as a short-cut for accepting or denying several
different stations who use the same Internet provider.
International Prefixes: Use this feature to
control access to your station according to the international prefix of
the other station's callsign. For convenience, EchoLink manages
these prefixes internally, and displays only the names of each country
in these lists. This feature has been provided to help you comply
with your country's rules regarding reciprocal control-operator
privileges or third-party traffic restrictions.
The countries in the Accept list are countries with which connections
will be allowed; those in the Deny list will be denied. To move a
country from one list to the other, select the country name (by clicking
on it), then choose one of the two arrow buttons in the center.
For example, if the only country in the Deny list is "United
States", any station with a U.S. callsign prefix (AAA-ALZ, KAA-KZZ,
NAA-NZZ, or WAA-WZZ) will be denied access; all others will be allowed.
Note that the countries listed are those in the ITU Prefix list.
There is no recognition of DXCC entities for this feature, and thus no
distinction between offshore territories and their host nations.
Also, EchoLink has no way to detect when a callsign is being used
outside of its country of origin.
Apply Security settings to: Use these two
checkboxes to direct EchoLink to apply the above security settings
to connections coming in to your station, to connections initiated by
your station, to both, or to neither. For example, if both boxes
are un-checked, the Security settings have no effect, and all
connections are permitted.
Signals Tab
The Signals tab lets you change the sounds (signals) produced by
EchoLink when certain events occur. EchoLink includes a set of
default sounds, and you can silence them or substitute your own WAV
files for each. These settings apply to Single-User mode
only.

The signals are as follows:
- Connected: A station has just connected (either
at your own request or theirs).
- Disconnected: A station has just disconnected.
- Alarm: A callsign in the Alarm list has
just appeared (or changed status) in the Station List.
- Over: A station with which you are speaking
has just finished a transmission (and has turned it over to you).
- Text Msg: A station to which you are
connected has just typed a text message (in the Chat window).
To preview any of the signals, click on the small
loudspeaker button.
These signals are used only in Single-User mode.
In Sysop mode, a separate set of signals is used..
