Narrow Band Emergency Messaging

FLDIGINarrow 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.

FLDIGI

Fldigi is the modem program and is used for keyboard to keyboard communications using a wide variety of modes including the popular PSK31 plus RTTY, DominoEX, MT63, Olivia, MFSK, Hell, Contestia, Robust PSK (PSKR) and others. Fldigi may be used for casual operating or, with several complementary applications, it may be used for emergency communications. For NBEMS, Fldigi is used with the following applications:

FLMSG

FLMSG is a simple forms management editor for the amateur radio supported standard message formats.
These current include:
• ICS-203 - Organization Assignment List
• ICS-205 - Incident Radio Communications Plan
• ICS-205A - Comms List - special USCG Plan
• ICS-206 - Medical Plan
• ICS-213 - emergency management report
• ICS-214 - Unit log
• ICS-216 - Radio Requirements Worksheet
• Radiogram - NTS message
• Plaintext - generic message format
• Blank - very simple text format with no preset fields
• Drag and Drop - target control (widget) that accepts either a data file (.203 etc), a wrapped data file (.wrap), or the text associated with a data file. The later may be a copy and paste from another application such as fldigi or a text editor.

It's data files are pure ASCII text that can be sent from point to point using the internet, amateur radio, or other electronic link. The data files are designed to minimize the transfer size. This is particularly important on amateur HF. The data file and the transfer file are one in the same, but can be further encapsulated using either flarq or wrap for the purpose of confirming the received file integrity.

FLWRAP

FLWRAP is a program that is used to apply a checksum and optionally compress messages and files for transmission by Fldigi. The checksum is used to confirm the accuracy of the transmitted message. Received messages are automatically saved to a file directory along with a timestamp.
