The Utah Amateur Radio Club IRLP Node #3352 Echolink Node #703269  On the Lake Mountain 146.760 repeater   -600 KHz offset, carrier squelch

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:

• PAUSE
• PAUSE
• PAUSE

• After keying up, wait at least one second before saying your first word.  If you begin speaking immediately, your first second or so may be cut off.  This can be especially annoying if the first thing you say is your callsign!
• Before replying to someone, wait at least two seconds!  Remember:  There may be other stations that wish to get in, or the other station may have dropped out briefly.

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?

• A Node is another radio system to which you can connect.  Connecting to another node is much like making a two-party telephone call in that the only ones connected are you and the distant node:  Anyone on another node that tries to connect to you or the to the node to which you are connected will get a polite message saying that the node is busy as a "Node-to-Node" connection involves those two nodes only.
• On IRLP, a Reflector is not connected directly to a radio system but is more of a "party line."  Multiple nodes can connect to a reflector and all nodes connected will hear everything that is going on with the other connected nodes.  Please note that while many can listen, only one can talk at one time.
• On Echolink, a Conference is similar to a reflector in that a number of different users may connect at once.
  

Sending commands:

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

• "This is <your callsign> for IRLP/Echolink Node #" followed the name/number of the node you are calling, the DTMF (tone) sequence - including the prefix code - and the node number.
• For IRLP nodes, you simply enter the node number after the prefix, as in:
• "This is KZ7PDQ for IRLP node #9999" followed by the prefix followed by the digits "9999"
• For Echolink nodes, you must enter a "*" (star) just before the node number, as in:
• "This is KZ7PDQ for Echolink node #9999" followed by the prefix followed by the digits "*9999"

• When you wish to disconnect from either an IRLP or Echolink node, say "This is <your callsign> disconnecting from IRLP/Echolink" followed by the prefix code and the digits "73"
  

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:

• You didn't speak loudly enough and your ID wasn't heard.  A lot of amateurs (especially newer ones) seem to be afraid to speak into the microphone and because of this, their audio sounds very low on the other end.  This is not a good thing!  Having very quiet audio makes it difficult for others to even hear you - including the control operator!

• You entered the wrong control code.  It is possible that you have mis-remembered the control code, or it is simply the wrong one, having been changed.  If your UARC membership is current, you can obtain the current code from the secretary.

• Your signal may be poor.  If your signal into the repeater is noisy and/or dropping out, you may not be able to issue the command sequence.  Remember that if your signal is too poor to send the control sequence, it's probably too poor to carry on a conversation, anyway.

• Maybe you unkeyed during the sending of the tone sequence?  You should stay keyed up from the beginning of your voice announcement until after you send the last digit of the tone sequence!  If you unkey at any time during this sequence, the computer will try to make sense of the digits it received and if it can't, your request will be ignored.

• Did you take too long to send the digits?  If you pause for more than a few seconds between any digit, the computer may "time out" while waiting for the next one.  If you need to do so, write down all of the needed digits - including the prefix, the "star" (for Echolink connections) and the node number before dialing.
  

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 Page.  The 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:

• You must say "This is <Your Callsign> connecting to IRLP node ####" followed by the control prefix followed by the Node Number.

Example:
If your callsign is "W7XYZ" and the control code were "123" and you wanted to connect to node "5678" you would do:
"This is W7XYZ connecting to node 5678" followed by the digits " 123  5678 "
• If you are successful in sending the command, you'll hear a voice status return.  This status could tell you that:
• You have successfully connected to the node.  Sometimes you'll also hear a short informational message about the node.
OR
• The node is currently busy.
• If you hear nothing at all, either the repeater is not in IRLP node or your command did not go through.  Remember to stay keyed up from the beginning of your voice announcement until after you send the last digit!
  

Connecting to an Echolink Node or Conference:

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

• You must say "This is <Your Callsign> connecting to Echolink node ####" followed by the control prefix followed by the "*" (star) key followed by theNode Number.

Example:
If your callsign is "W7XYZ" and the control code were "123" and you wanted to connect to node "5678" you would do:
"This is W7XYZ connecting to Echolink node 5678" followed by the digits " 123 * 5678 "
• If you are successful in sending the command, you'll hear a voice status return.  This status could tell you that:
• You have successfully connected to the node.  Sometimes you'll also hear a short informational message about the node.
OR
• The node is currently busy.
• If you hear nothing at all, either the repeater is not in Echolink node or your command did not go through.  Remember to stay keyed up from the beginning of your voice announcement until after you send the last digit!

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:

• You must say "This is <Your Callsign> disconnecting from the node" followed by the control prefix followed by the " 73 ".

Example:
If your callsign is "W7XYZ" and the control code were "123" you would do:
"This is W7XYZ disconnecting from the node" followed by the digits " 123  73 "
• If you are successful in sending the command, you'll hear a voice status return telling you that you have disconnected.
• If you hear nothing at all, either the repeater is not in IRLP node or your command did not go through.  Remember to stay keyed up from the beginning of your voice announcement until after you send the last digit!
