One of the great features of FLDIGI is the ability to setup a station that can monitor Narrow Band Emergency Message System (NBEMS) messages and to then have those messages either pop-up in a FLMSG window or a browser window or both. This is useful if you are away from your station during an event .
There a number of steps to setup your station correctly and this HOWTO guide will step you through that process.
To begin with it is recommend that you download and install the latest FLDIGI, FLMSG and FLWRAP applications from http://www.w1hkj.com/download.html
If you are installing on a Windows Vista or Windows 7 machine it is recommended that you install to a folder where your logged in user has both read/write permissions. For example, installing to C:\NBEMS
Once you have FLDIGI, FLMSG and FLWRAP installed we need to configure FLDIGI to detect the different modes that may be transmitted and to then display the messages received.
1. To setup FLDIGI to detect messages sent using the Reed-Solomon ID you need to enable the RxID feature. When this is enabled and a message is sent with a Reed-Solomon ID FLDIGI will detect that message within the current passband and automatically center on that message, switch modes and start to decode the message. To send messages with the Reed-Solomon ID the TxID feature needs to be enabled. Recommend that you have both RxID and TxID enabled.
2. You may want to fine tune the settings for the receiving of the Reed-Solomon ID’s to do this select Configure | IDs from the FLDIGI menu.
3. If you want to search the entire passband for Reed-Solomon IDs check that option. When the option is unchecked FLDIGI will limit the search to +/- 200Hz of the current center frequency on the waterfall. Once you have made your changes make sure to click Save and then Close.
4. To select which modes will be detected click on the Receive modes button.
In the example above I am only interested in detecting MT63 and Olivia messages.
5. Now that you have FLDIGI setup to detect messages sent with the Reed-Solomon ID the next steps are to configure FLDIGI to extract messages that have been wrapped using FLWRAP or FLMSG and to pop open those messages in either FLMSG, your internet browser or both.
6. Select Configure | Misc from the FLDIGI menu. From the second row of tabs select NBEMS.
7. The first step is to locate the FLMSG executable file. Click Locate flmsg and navigate to the location where you installed FLMSG and select the flmsg.exe
8. Next step is to decide if you want the messages to open with FLMSG or in your default Internet browser. In the example above I have both, it’s personal preference.
9. Verify that you have the check box Enable under NBEMS data file interface checked.
10. Click Save then click Close.
Congratulations your station is now setup to detect messages (that you specified in Step 4) that are sent with a Reed-Solomon ID . If the message was sent as a wrapped message using either FLMSG or FLWRAP the message will pop up in either FLMSG or your Internet Browser or both.
