I received this invitation through the Winlink-Programs-Group (Google group) and just registered successfully. It looks useful to me. First-come first-served.
Due to extremely high interest, we have scheduled a second session of our webinar entitled “Introduction to Radio Relay International and the International traffic system” to take place on Tuesday, October 13 from 1:00-PM to 3:30-PM EDT (1700Z to 1930Z).
The class covers the structure of the traffic system, its international affiliates, and the structure and topology of the manual mode net system, the Digital Traffic Network (DTN), and the Winlink-RRI Radiogram transfer process. Also included is an introduction to the radiogram and radiogram-ICS213 message formats including an explanation of the various components incorporated in their associated network management data.
A general overview of RRI management philosophy and RRI emergency response functions are also included. Training certificates will be issued for RRI Training Class TR-002.
The class is limited to 100 people. Register soon, as the first class filled up in just a few hours.
