User's Guide

Getting the control prefix

A control prefix (or "access code") is required for controlling the IRLP/Echolink connection on this repeater and is available to you if you are a current UARC member.

The current prefix is in the PRINTED version of the most recent Microvolt (but not the online version) on the inside front cover.  If you didn't get the Microvolt  - but should have - OR if you have chosen not to get a printed copy of the Microvolt but you are a member, contact the secretary. 

Once you get the code:

  • Please, do not give it out over the air!
  • Do not give it to non-members
  • Out-of-town visitors or occasional guests may use the node, but a UARC member should be operating the node and monitoring during this time.
Note that the code will change occasionally, but there will normally be an overlap period where both codes will work

Welcome to UARC's IRLP and Echolink Node!  This node is part of the IRLP network, the Internet Radio Linking Project, linking many radio systems across the globe connected via the internet.  With this network this repeater may be connected to one or more other linked radio systems providing access to these other places via 2 meters.

This node is also connected to Echolink as well, a system similar to IRLP, but with a different philosophy and emphasis:  Where IRLP is intended to be used only for RF-connected links, Echolink offers a wider variety of connection options.  For more information on the differences between IRLP and Echolink, see the IRLP and Echolink Wikipedia pages.

Please be aware that while the 146.76 repeater itself is available for all amateurs to use, its autopatches and the node are reserved for UARC members only and out-of-town guests.  Why is this done?  It seems only fair that those using the system help support it.  Also, restricting access to members only can help prevent abuse of the system.

Before going any farther, please read IRLP/Echolink Operating Guidelines.

This is a common-sense guide that briefly explains hows, whys, and etiquette of IRLP/Echolink operation.

Talking on the node:

"Speak up - they can't hear you!"

If you have listened to the radio for very long, it has probably occurred to you that a number of people seem to be afraid of their microphones and hold them quite some distance from their mouth!  This causes their transmitted audio to sound very quiet, making it extremely difficult for the station(s) on the other end to even hear you.

Remember:  Microphones for mobile radios and HTs are designed to be held only an inch or two from the mouth.  Why?  If they were more sensitive, they'd pick up too much vehicle or room noise and be unusable!

Pauses are important:

Using and IRLP node is much like using a linked repeater system - and there are three things to remember:

As with any linked system, it takes a short amount of time for the system to come up and "turn around" between transmissions, so pausing a bit is absolutely necessary to prevent having your first several words cut off and/or preventing "doubling" amongst parties. Don't hog the channel!

Like on any linked system, there may be a lot of people listening - and a lot of people who would like to talk as well.  Try to avoid long-winded transmissions and excessively long QSOs - especially on reflectors!

Don't carry on "local" QSOs when linked!

Be courteous to others when the system is linked (especially when it is linked to a reflector or conference) and avoid "local" chatter:  It is of no interest to the ham in Australia that you have just picked up groceries and the kids and are headed home!

If you need to make such an exchange, please move to another repeater (or go to a simplex frequency) or disconnect the node!

Soliciting contacts:  Saying "Monitoring" doesn't mean that you want to talk...

Often one hears someone get on the air to report that they are "monitoring."  This would seem to be pointless as one need not tell the world that he/she is "monitoring" - you don't even need a license to "monitor" let alone make a transmission!

If, what you really wish to do is make a contact, say so - and "CQ" is recommended.  It is perfectly appropriate to make a short CQ to announce that you are looking for someone to talk to!  It is true that some repeater operators don't like CQ's, but IRLP etiquette permits a short call like "This is W7XYZ calling CQ" to let others know that you are looking for a QSO.

How to tell if the transmission came from the internet link - the courtesy beep:

Any transmission that comes from the internet (via IRLP or Echolink) will end with a special "beep" just before the repeater drops and if you listen carefully, you can tell whether the person that just talked was coming over Echolink or ILRP.

If the transmission came from IRLP:

You will hear a "di-dit" (two "dits" - the letter "I" in Morse code) just before the repeater drops.

If the transmission came from Echolink:

You will hear a "dit" (just one "dit" - the letter "E" in Morse code) just before the repeater drops

Note that ONLY those listening to the 146.76 repeater will be able to hear this:  No-one on the internet can hear it or the repeater's Morse ID.

If you do NOT hear either a "dit" or "di-dit" just before the repeater drops, the transmission was local, via '76 and not from the internet!

Be responsible for your connections:
If you bring up a node, you are responsible for taking it down again when you are done - or at least handing it off to another responsible party.

Using the node:

"Nodes" versus "Reflectors" versus "Conferences - what's the difference?

Sending commands:

It is required that all commands be preceded with an ID of the station and announce their intention.  The following is recommended:

The control operator may wait until he hears a legitimate ID before he presses the 'Authorize' button and lets the sequence go through.  If the command did not go through, wait a few seconds and try your ID and the sequence again.

If this still doesn't work, it may be because of one or more of the following:

Putting the repeater in IRLP/Echolink Mode:

By default, the repeater is always in the "IRLP" or "Echolink" mode - that is, it can, at any time, accept incoming connections or allow local user to "dial out" to other places in the IRLP network. Note that a few people (control operators, "official" UARC repeater monitors, etc.) have the code required to disable the node - but this should be the exception rather than the rule.

Please note that it is possible to disable just the IRLP portion, only the Echolink portion or both!  Again, this would be the exception rather than the rule.

To check the current IRLP node status, look at the Node 3352 Status Page and look at the line that says "Current Node Status" - if it says "Idle" then the node is awaiting a connection.  If it says "Online" it is already connected to another node or reflector.  It is only if it says "Offline" that the node is not available for IRLP connections.

To check the current Echolink node status, look at the Echolink Status PageThe status of the "W7SP-R" node should be at or very near the top of the list.

Connecting to an IRLP Node or Reflector:

The sequence for connecting to a IRLP node or reflector is as follows:

Connecting to an Echolink Node or Conference:

The sequence for connecting to a Echolink node or conference is as follows:

Disconnecting from an IRLP or Echolink Node, Reflector or Conference -  the "73" command:

The sequence for disconnecting from either an IRLP or Echolink node is as follows:
