How to Conduct the NBEMS Exercise
Conducting an NBEMS Exercise
Required: You should be comfortable working NBEMS Exercises, and have sufficient signal to cover the net.
INTRODUCTION
NBEMS Exercises conducted by Guest/NCS use standard ORCA NBEMS Exercise format. Exercise files will initially be generated by NCS. Exercises are designed to practice key traffic-handling tasks briskly: content is secondary, it mainly adds realism to the Exercise.
Guest/NCS will host <10 participating stations. These Active stations are easy to identify in the Roster. There are no spaces before their CALLSIGN. QNX stations have two spaces before their CALLSIGN. Your focus is <10 Active Ops ONLY.
BEFORE NET
Obtain: Exercise file from NCS, ie: ‘ex345_URCALL.txt’
Choose: 3 Modes based on condx. PSK-250R, THOR-50×1, & MFSK-32/22 are good beginning modes.
Load: Have Macro file active, ‘ORCAbasicEx.mdf’
Edit: Add 3 Modes to ‘NBEMS EX’ Macro
Prepare: pencil/paper grid to log Fill Blocks*
In FLAMP
Add: Exercise file to TX screen, ‘Transmit Queue’
Change: ‘Send to’: from QST to ORCA DIGITAL NET
Set: ‘Blk size’ to 64
Set: ‘Hdr Rpt’ to: 2
Check: ‘Comp’ OFF
*Prepare pencil/paper grid to record missing blocks & CONFIRMED stations
Paper grid has 4 columns, CALLSIGN,Mode1,Mode2,Mode3, and <10 participant rows.
Track station Reports with these characters:
Missing blocks = 1,2,3, etc
CONFIRMED = horizontal line
No Copy = NC
No Reply = NR
