ILRP Information


Before using ILRP #

Please be considerate.
Ensure that you have a solid connection to the repeater before you attempt using the node.
Do not connect via Echolink or initiate a connection during drive time.
Do not connect to the repeater via Echolink to monitor the repeater. We can only have one type of connection at a time, and this will consume it.
Ensure that you have tested your Echolink on the Echolink test server first.
Do not use the repeater as a testing node.
Abuse will not be tolerated. Be sure to follow all FCC rules.

The Danvers repeater is very busy. When folks are commuting, we already have enough trouble with some of the more long winded talkers, so let’s not add to the confusion.

If you are connected to the repeater via Echolink, you will not be able to hear any traffic over the autopatch, even during net mode.

In order for the node to work, the following must be true:

  • The repeater must have the link enabled
  • The EchoIRLP box must be enabled.

These operations are available only to control operators, and if neccessary, the control operator may require the connection to be closed and/or disabled during certain events.

Once the above has been accomplished, you may connect to other nodes in several ways.

How to use ILRP #

Connecting to other nodes #

To use the node(s) via RF:

  1. Know the node number you want to connect to before you start!
  2. Ask if the connection is in use, be sure to wait a few moments for a response.
  3. Using your radio, key-up, say your callsign and intentions and the enter the dtmf code for the node or reflector you want. The code is the prefix followed by the node number.
  4. When you are finished be sure to announce your intentions and the enter 73 in dtmf to disconnect.

The IRLP Prefix is: A
The Echolink prefix is: *3

To connect to the repeater via echolink on a pc:

  1. Fire up Echolink
  2. Make sure you sound ok through the test reflector
  3. Connect to NS1RA-R
  4. Don’t forget to disconnect when you are done

Node information:

Repeater: NS1RA / Danvers, MA / 145.470 (-) PL 136.5
EchoIRLP: NS1RA-R / Danvers, MA / IRLP:4427 / E:314375

Tips #

  1. be patient
  2. wait
  3. WAIT
  4. If you are connected via the internet, wait about 15 seconds after the initial connect and then make a transmission, this will allow the repeater to finish its ID before you transmit avoiding confusion during the first transmission from the RF side.

Generally you will connect to a node and then wait about 15 - 30 seconds for activity. Remember, the link is half-duplex. If it is talking, you cannot talk or enter commands! When you key-up your first 50-100 miliseconds (about 1/10 of a second) or more will be truncated. So key-up, wait, then talk. After the other party un-keys, wait about 1-2 seconds before keying up.

There is an inherent delay over the internet and through any of the other links required to get it all to work. Have fun and be careful. Don’t forget all of those third party traffic rules when you connect to either a reflector or a node in another country!

Terms defined #

Node: an ILRP or Echolink station
Reflector: a special IRLP server that will allow many nodes to connect together (a party line)

Some reflectors to try #

  • A9123: Reflector 9120 channel 3. New england Network.
  • A9250: Reflector 9250 channel 0. Las Vegas reflector (many stations around the world)
  • A9990: Echo/test reflector. This will re-transmit back to you your audio, good for testing
  • *39999: Echolink echo/test reflector. Same as A9990 but uses echolink instead of IRLP.

Good Luck and have Fun!

Additional commands are available to control operators! See Lou for details.
