In looking over the several different digital packages available for EmCom type communication, here is a brief summary of the packages I know about. Basically, all of these are sound card based. I'm sure there are others available as well.
I have discussed several of these programs in earlier posts. I will be updating this summary as I find out more information. Anyway, here goes ...
NBEMS - Narrow Band Emergency Message System - is detailed in an earlier post. In summary, though, here are the essentials:
1. Has a Windows and Linux Version.
2. Uses Fldigi and Flarq (ARQ provides error-checking)
3. Modes - RTTY, PSK31, PSK63, PSK125, PSK250, MFSK
4. GUI is easy to use. Can send small files.
OUTPOST - Uses BBS System
1. Windows
2. Uses own program
3. Modes - PACKET
4. Excellent GUI includes a message form maker to pre-format messages. Includes NTS, Bulletins, and Private Message form.
EcomScs - Uses BBS System but provision for email
1. Windows
2. Uses own program
3. Modes - PACKET
4. GUI allows creation of message forms. BBS connection and Keyboard to keyboard messages.
5. Extended product called GateWayScs provides a temporary mail box if BBS not available and CAN BE connected to the internet for email.

Narrow Band Emergency Messaging System
Also in the April 2008 issue of QST, there was a short mention of the Narrow Band Emergency Messaging System which is based on PSK, RTTY, or MFSK rather than Packet messaging.
NBEMS was developed by Skip Teller, KH6TY, creator of DigiPan and Dave Freese, W1HKJ, creator of the Linux-based Fldigi.
In my estimation, this program suite takes direct aim at the much-touted and expensive Winlink process.
Together, NBEMS package lets you exchange text and small files in several modes using ARQ - Automatic Repeat reQuest. As you may or may not know, ARQ supports checking and resending data to provide error free transmission of data.
Everything is handled through sound card interfaces so no expensive TNC is required.
Fldigi program puts you on the air on RTTY, PSK31, PSK63, PSK125, PSK25 and MFSK. If you want to use the ARQ features, then the Flarq program interfaces with the Fldigi to make it happen.
There is a very active Yahoo Group supporting NBEMS testing on VHF and 30 meters. Good success has been had with communication between VHF FM mobiles even using vertical antennas. This opens up all kinds of possibilities due to the many hams with this equipment.
