How to Conduct the NBEMS Exercise

Conducting an NBEMS Exercise

Prerequisite: Experienced & comfortable with ORCA  NBEMS Exercises, sufficient signal for general coverage.

INTRODUCTION
ORCA NBEMS Exercises conducted by Guest/NCS use standard ORCA Exercise format.  Exercises are designed to practice key traffic-handling routines briskly. NBEMS Exercise files will be provided.

Only Active stations participate; they’re easy to identify in the Roster.  There are no spaces before their CALLSIGNs.  QNX stations have two spaces before their CALLSIGN.  Your focus is Active stations ONLY.  NBEMS Exercises are limited to 12 stations. When more than 12 stations ck-in Active, we add an * to their CALLSIGN*.  You only work the 12 Active stations. Stations w/CALLSIGN* DO NOT participate.
