 *****************
 Extension Packets
 *****************
+
+If the NGHam extension flag is set, the Payload contains NGHam extension data. Each NGHam extension packet has a separate header, describing the type and size of the following data. A payload can contain multiple extension packets, each containing information such as position, callsign, timing information, statistics, destination, repeating information and others. Below there is a figure with a diagram illustrating the format of a NGHam Extension packet.

+.. note::
+   Since the extension packets are not fully implemented and documented in the original NGHam implementation, the support for this resource is not complete yet. Some extension packet are already implemented and working, and some are not implemented because of lack of information about it. In the future, a definition of these packets are planned to be done.
