Introduction to NBEMS:
Narrow Band Emergency Messaging Software (NBEMS) is an Open Source software suite that allows amateur radio operators to reliably send and receive data using nearly any computer (Windows, Mac, and Linux) and any analog radio without requiring a dedicated digital infrastructure or specialized modem hardware. NBEMS works on both VHF/UHF FM and on HF. In this presentation you will learn the basics of sending and receiving data using Fldigi. You will see how to easily send and receive verified files and forms using Flmsg. You will learn one way to integrate NBEMS with a high-speed Broadband Hamnet mesh network. NBEMS is the standard digital emcomm package for Western PA ARES.
In this follow up to Introduction to NBEMS you will learn how to send and receive ICS-205, ICS-206, ICS-213, ICS-214, and ICS-216 forms in addition to ARRL Radiograms with Flmsg; you will learn about new high-speed modes in NBEMS; you will see how to deal with large data files using both Flarq and Flamp; you will look at real-world throughput benchmarks and we will provide recommendations for how best to send your data; and you will learn how to make a monitoring station automatically handle changes in NBEMS modes.
