Amateur Radio Simulator

App_rpt-users

Hi,
      I am a software engineer. Needed to simulate Amature Radio over
VOIP. Below are my inquiries.

My understanding of app_rpt, is

                   Links Base Nodes, with other Base Nodes, with VOIP.
                   Links Repeaters with Base Nodes, VOIP.

I am not a hardware engineer, ok, so the repeater to Linux interface
might need some hardware. So app_rpt manages that??? Same is for Base
Nodes???

                    What is my problem here?

                   I have to build a system where users communicate
through their microphone head set, to the other receivers/transmitters
(also on the computer), like emulating an Amateur Radio environment,
through VOIP. Different users on different frequencies, all
communicating with each other, Linked through a server like Asterisk.
A typical VOIP conference call, though we have to provide frequencies
like Amateur radio.

                   Now the above problem can be done with Asterisk.
But since app_rpt is for specially Amateur Radio environments, how can
I use the functionality provided by app_rpt.

                   app_rpt links the Base Nodes/Repeaters would it be
useful as a server for managing users at their frequencies
communicating, adding it's extra capability of linking nodes.

                   I don't need the hardware support from this module,
as I am using just a microphone head set.

                    Any replies will be greatly appreciated. I have
already been through a lot of research to reach to Asterisk first,
then a client, then app_rpt. And the app_rpt site is very hardcore
technical stuff.

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.

Hi,
     I got the thing right, this time I guess. The basic concept of app_rpt is:

       To provide VOIP as a channel of communication to remote
distances where Radio Signals cannot reach, but VOIP can. Normally we
use Repeaters and Remote Bases but using Internet is cost effective
and is an alternative. After all it's for Amateur Radio's so special
equipment is needed and interfaced to the PC, there by, getting the
Radio Internet signals interchanged.

       Now in my application all I need to do is conference call at
all frequencies, between computers. No where I need a transceiver to
do the call. So no repeater controllers needed, no Remote Base Nodes
needed.

       I think this simple scenario can be done with, Asterisk
Conference Configuration. If I need to configure frequencies, the
channels of Asterisk can be used. Means channels dedicated to all
frequencies.

      Later If I needed to telecast, from computer to repeater, or
Base Station, or radio Station, there I might need app_rpt.

     Thanks for your time and help.
