The W8FY-R EchoLink Node is configured to accept commands through the local 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 and B).
The 0 used after an A is a zero.
The table below lists each of the DTMF commands.
| Command | Description | Input |
| Connect | Connects to a station on the Internet, based on its node number. | A+num |
| Connect by Call | Connects to a station on the Internet, based on its callsign. | AB+call+# |
| Random Node | Selects an available node (of any type) at random, and tries to connect to it. | A00 |
| Random Link | Selects an available link or repeater (-L or -R) at random, and tries to connect to it. | A01 |
| Random Conf | Selects a conference server at random, and tries to connect to it. | A02 |
| Random User | Selects an available single-user station at random, and tries to connect to it. | A03 |
| RandomFavNode | Selects an available node (of any type) at random from the Favorites List, and tries to connect to it. | A001 |
| RandomFavLink | Selects an available link or repeater (-L or -R) at random from the Favorites List, and tries to connect to it. | A011 |
| RandomFavConf | Selects a conference server at random from the Favorites List, and tries to connect to it. | A021 |
| RandomFavUser | Selects an available single-user station at random, and tries to connect to it. | A031 |
| Disconnect | Disconnects the station that is currently connected. If more than one station is connected, disconnects only the most-recently-connected station. | # |
| Disconnect All | Disconnects all stations. | ## |
| Reconnect | Re-connects to the station that most recently disconnected. | A09 |
| Status | Announces the callsign of each station currently connected. | A08 |
| Link Down | Disables EchoLink (no connections can be established). | (none) |
| Link Up | Enables EchoLink. | (none) |
| Play Info | Plays a brief ID message. | * |
| Query by Call | Looks up a station by its callsign, and reads back its node number and status. | A07+call+# |
| Query by Node | Looks up a station by its node number, and reads back its callsign and status. | A06+num |
| Profile Select | Switches to a different stored set of configuration settings (0 through 9). | AB#+num |
| Listen-Only On | Inhibits transmission from RF to the Internet. | A0511 |
| Listen-Only Off | Restores normal transmission from RF to the Internet. | A0510 |
Connect
The Connect command is to use the `A' key, then enter the 4- 5-, or 6-digit node number to which you wish to connect.
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. We currently don't have any defined shortcuts.
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".
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.)
Enter: A 9 9 9 9
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*".
Enter: A 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.
Enter: A 0 1
EchoLink responds with:
"CONNECTING TO K-1-O-F REPEATER"
followed by
"CONNECTED"
because K1OF-R was selected at random.
