Nodes are generic. They can be configured as repeater (full duplex) or base station
(half-duplex) operation. There is no difference in the way half-duplex and full duplex
nodes connect to each other. Multiple connections are handled by each node only limited by network bandwidth
and PC processing power. All receive audio is mixed and retransmitted to all other connected nodes. No node has audio
priority over any other node.


App_rpt can be configured as a single or multi-node system on the same PC. App_rpt usually manages a hardware radio
interface on a per-node basis, however a node can be operated "headless" as a conference server as well. One radio
hardware interface is assigned per node. Hardware radio interfaces supported are the QRV Communications LLC Quad Radio
PCI card and the DMK Engineering URI.
