Echolink is a great system for communications between Amateurs. It combines VoIP technology combined with RF Gateways to link repeaters, simplex links and users. Those are the three types of EchoLink setups. You don't need a computer for the repeater and simplex type links. In these two types the computer is provided for you at the link site. For these two types all you need is a trasceiver (mobile, base, or handheld) with a DTMF keypad.
Node Numbers work like dialing a phone number to get someone on the other end. The KB9TMP-L node number is 7492 so if your buddy in Carjackistan wants to have a QSO with you all he has to do is enter the numbers 7492 into the link that he is using and it will connect to the KB9TMP-L link. The same thing applies to you making a connection to him, all you need to know is the node number that he is listening to. Just key up your radio, press the correct numbers on your keypad and wait for the connection to be confirmed. Remember that you can connect to any of the three types of setups, repeaters, simplex links, and PC users. Also remember that there is a small delay in the system even on the fastest of connections, but not that noticable once you get used to using EchoLink.
Is It Working? Is Anybody There?
When you hit the 08 command if there is no active connection to any nodes the computer will say 'not connected', this doesn't mean the EchoLink is not on, just that it's not connected to any links. When the EchoLink is not on you will hear NOTHING from the DTMF codes. If you want to know who all is connected to EchoLink right now you can view the Current Logins web page on the EchoLink Website.
To access the link you will need your radio set at 145.720 MHz with a PL of 136.5 Hz. I have the timeout timer (TOT) set to 5 minutes (2 minutes weekdays 6am - 3pm) and 1 minute for a 'dead key'. If your connection gets dropped because the other ham is long winded or fogets to stop transmitting, just reconnect (by pressing 09) and keep on going. If you forget what the buttons do, pressing star, eight, eight, (*88) plays the ON AIR help from the computer. ( see list below )
Where Is It Located?
The KB9TMP-L link is located on the east side of Bedford IN, near Lincoln Elementary School. The links operating area is approximately 10 to 12 miles as can be seen on the map below.

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".
To connect to node number
Enter: 9 9 9 9
EchoLink responds with:
"CONNECTING TO CONFERENCE
because 9999 is the node number of conference
To get the status of K1RFD:
Enter: 0 6 1 3 6 4 4 #
EchoLink responds with:
because 13644 is the node number of station K1RFD,
and K1RFD is currently busy.
To connect to a random link
Enter: 0 1
EchoLink responds with:
"CONNECTING TO K-B-9-O-H-Y REPEATER"
because KB9OHY-R was selected at random.
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".
