On the frequency shown above, key down and dial the 4 digit number of the node you wish to connect to, then un-key and wait for the a message.  If your connection was successful you will hear the other node's greeting message.  If the other node is busy, you will receive a message stating so.

Once connected to another node wait at least 5 seconds after the greeting message before keying down to make sure there is not conversation already in progress on the node you connect to.  Sometimes you'll be connecting to a repeater, other times you may be connecting to a simplex station.  It depends on the equipment at the node to which you connect.

When the QSO is handed back to you, wait 5 seconds again before transmitting. This is particularly critical when connected to a reflector. No station can disconnect while someone else is transmitting on a reflector.  Waiting 5 seconds gives others time to disconnect.

After you key down, wait at least 1 second before talking. This allows time for the internet to key the other node's transmitter.

To disconnect simply key down, dial 73 and un-key.  You will then hear the other node's disconnect message.
