Hi Rod, The NBEMS setup uses soundcard technology. Although the TNC will provide you with packet capabilities (which can be important depending on where you are and what's available in your area), the NBEMS technology relies on various soundcard-based modes and doesn't use hardware based packet at all AFAICR.
Keep your TNC in case you want to run Airmail, but also setup a soundcard interface to use the NBEMS software and modes. Also, you might want to look at the Paclink software which will work better with your TNC than Airmail will. 73, Jeff Moore -- KE7ACY DCARES - Deschutes County ARES ----- Original Message ----- From: Rodney Subject: [digitalradio] NBEMS NBEMS - Narrow Band Emergency Messaging System Is anyone familiar with this mode? What type of equipment is needed? I have an MFJ-1250C. Will this work with this or will I need a different type of interface? Thanks! Rod KC7CJO
