Basic NBEMS Exercise

How to Conduct our Basic NBEMS Exercise

Conducting a Basic NBEMS Exercise

Required: You should be comfortable working the Basic and Advanced NBEMS Exercises, and have sufficient signal to cover the net.

Basic NBEMS Exercises conducted by Guest/NCS use standard ORCA Exercise format. Content will be News stories relevant to radio, digital operating strategies, tactics, and tips, or station redundancy. Exercise files should be +/- 2min/MFSK-32. Summarize the topic and provide URL/Reference. Exercises are designed to practice key traffic-handling tasks briskly: content is secondary, it mainly adds realism.

Guest/NCS will initially have 8 participants. Those stations are easy to identify in the Roster. There are no spaces before their CALLSIGN and no *, ie: CALLSIGN*. CALL* Ops do not participate. QNX stations have two spaces before their CALLSIGN. Your focus is up to 8 Active Ops ONLY.

Choose: Topic, Name file in sequence, ie: ‘ex123B_URCALL.txt’
Choose: 3 Modes based on condx. PSK-250R, THOR-50×1, & MFSK-32/22 are good beginning modes.
Load: Have Macro file ready, ‘ORCAbasicEx.mdf’
Edit: Add 3 Modes to ‘NBEMS EX’ Macro
Prepare: pencil/paper grid to log Fill Blocks*

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
