APRS is not required to participate in SKYWARN nets, but spotters are asked to turn it on if available. CCARES will use APRS at the discretion of an NCS to help manage the position of spotters. Members are encouraged to consider developing equipment that can perform both APRS and WinLink functions (not necessarily at the same time).

For safety reasons, CCARES discourages net participants from using a laptop and smart phones in their vehicles during nets.

The D/FW area contains a heavy concentration of APRS users. In order to keep the system from being overloaded, all APRS users are requested to use the following settings:

APRS Settings
