IRLP Node Quick Reference

The Darwin IRLP Node 6343 can be accessed via the local repeater VK8RTE on 147.000 MHz. To connect key in "Node number" to disconnect key in "73". For a guide to correct node operation read the IRLP Node Operation section below.

IRLP Node Re-Broadcasts

We now re-broadcast the following news broadcasts originating from the US on IRLP node 6343 repeater 147.000.

ARRL News - Sundays at 1400 CST (2.00pm) runs for 15 mins.
ARNL (Amateur Radio News Line) Mondays at 2000 CST (8.00pm) runs for 30 mins.
TWIAR ( This Week in Amateur Radio) Wednesdays at 2000 CST (8.00pm) runs for 2 hours

These broadcast give an update of the current happenings in the US and around the world in Amatuer Radio and related electronics issues.

Also a re-broadcast of the WIA news on Sunday evenings at 2000 CST (8.00pm) runs for 30 mins approx. with a Informal callback / chat session.

The node also automatically connects to the VK Virtual Pub Net to Reflector 9500 at 1900 CST (7.00pm) to 2200 CST 910.00pm) which is a informal net of many VK repeaters all connected together as a multi user chat session, there are no designated net controllers, just call in and have a chat.

IRLP Node Operation

The user interfaces to the IRLP Node by using DTMF signals sent over the radio. First you need to establish the node number that you wish to contact. A list of current nodes can be found on the IRLP homepage.

Once you have established the node to call go to the local node freq of 147.000 (VK8RTE), listen to ensure that the channel is clear, ask if the repeater is in use. Identify the node that you are about to call by voice and then key in the node number.

A slight delay will occur with the repeater being held open, When the connection is confirmed, the voice ID of the destination node will be transmitted back to you as well as your nodes voice ID to the other repeater.

NOTE: If your node is already connected to another node or reflector, a greeting will play saying; - "your node is currently connected to...ID of the connection") In this case confirm if anyone desires the connection to remain up before dropping by using the OFF code..

Once connected and after hearing the confirming voice ID, wait at least 15 seconds before transmitting as the following conditions may occur:
the repeater may be in use, and your entry may have occurred between transmissions.

If the voice ID of your node is longer than the voice ID of their node, and the connection is not made until the ID is fully played.

Their computer may be slower, and hence take longer to process the connection than yours.
Press and hold the microphone PTT for a second and then announce your presence and your intention such as you are calling someone specifically or just looking for a QSO with another amateur in that city.

If no response is heard, announce your call and your intent to drop the link and then touch- tone in the OFF code which is "73". Not a good idea to transmit touch-tone commands without first giving your call-sign. Not only is this courteous it is a regulatory issue in some countries who may be connected to the reflector.

Some nodes are configured so you cannot connect to them if that repeater is active. In this case you will receive the message "The node you are calling is being used locally" If you receive this message wait 5 or 10 minutes and then try again. If you stay connected to a node and there is no activity on your repeater for 4 minutes, the connection will time out and automatically disconnect with a voice ID disconnect message on both nodes.

While repeaters "A" and "B" are connected, anyone attempting to connect with either node will be told by a recording that - "The node you are calling is currently connected to callsign" however all local traffic on each repeater will be heard on the other repeater as well.

Don't forget if you require any more detailed information visit the official IRLP web site.

Echolink Node Quick Reference

The Darwin Echolink Node VK8DA-R node number 288680 can be accessed via the local repeater VK8RWI 439.975 MHz. To connect key in "Node number" to disconnect key in "#". For a guide to correct node operation read the section below.

EchoLink Node Operation

The EchoLink system is similar in many ways to IRLP and the same operating etiquette needs to used. The main variation is that you can connect to either another RF node of an amateurs computer system. The user interfaces to the EchoLink Node by using DTMF signals sent over the radio. First you need to establish the node number that you wish to contact. A list of current nodes can be found on the EchoLink homepage.

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.)

To connect to node number 9999:
Enter: 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*".

To get the status of K1RFD:

Enter: 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.

To connect to a random link or repeater:
Enter: 0 1

EchoLink responds with:

"CONNECTING TO K-1-O-F REPEATER"

followed by:

"CONNECTED"

because K1OF-R was selected at random.
