The CARDX is abreviation to Campina Amateur Radio DX Group. Its a group dedicated to research on DX TRX´s, propagation, build Ham system, projects, contact challengers, meetings, design antennas, equipments, devlopment and test systems.



Recently, we build an network of radios, to interlink some frequencies. Here is the project:



Using the Internet system, we connect with other cities, and all members of CARDX talks on the fix frequencies. VHF and UHF radios are CTCSS used code to close the link system. In a 10 meters, we use a Split frequencies. Me and PR7SG have devloped a mobile system. I create an interface to control Cellular phone on Radio TRX.

The system used is Freeband EQSO.

This is the window:



But we try connect to other system, called CQ100. This link enter on a network, using other dedicated server.



Well... This system have tested for long time, but still it needs to make repairs, that is, still it is in development.
