Making A Direct Connection
This will connect our repeater to one other repeater.
- First of all listen for at least 15 to 30 seconds before transmitting Ask if the repeater is currently in use Wait for the all clear Give your call sign and the node name or number you wish to call. Example: VE3xyz for the Sydney node Press the PTT, wait one second, enter the node number on your DTMF keypad, wait one second, release the PTT The repeater should come up with a carrier as it waits for the connection to be authenticated, this can take a few seconds 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 If your node is already connected to another node or reflector a greeting will play saying that your node is currently connected Some nodes are configured so that you cannot connect to them if their repeater is active In this case you will receive the message "The node you are calling is being used locally". Wait 5 or 10 minutes and then try again Once your are connected and after hearing the confirming voice ID wait at least 15 seconds before transmitting : The repeater may be in use, and your entry may have occurred between transmissions The voice ID of your node may be longer than the voice ID of their node Their computer may be slower, and hence take longer to process the connection than ours Press and hold the microphone PTT for THREE seconds before taking give your call sign and calling node name or number Have fun...
- When you are finished, announce your call sign and your intent to drop the link. Press the PTT, wait, key in the numbers 7 and 3 on your DTMF keypad, release the PTT. You will hear a voice message confirming that you have dropped the link 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
Connecting To A Reflector
This will connect our repeater to a computer on the internet. Other repeaters can also be connected to this computer at the same time
- Follow the direct connection procedure
- Enter the reflector node number
