Hi Sam,
Yes, we are a network of linked repeaters so, when someone it transmitting on say the Live Oak (NE) Repeater, all the other repeaters and nodes connected to the hub are also broadcasting that transmission. You can look at our status page and see what repeaters are connected and when someone is transmitting. http://www.alamocitygmrs.com/supermon/link.php?nodes=1510,1512,1513,1680,1684
