There is an interesting article in August QST, pages 73 - 74, about the NBEMS (Narrow Band Emergency Messaging System) software.
NBEMS can be used to transmit bulletins & binary files using the MT63 digital data mode over FM simplex or repeaters using accoustical coupling. There is no need for a sound-card, TNC, external modem, radio & computer interfacing, modified radios or dedicated digital radios / infrastructure. Dave, KB3FXI & Harry, W3YJ, ARRL Assistant SEC, Western Penn. section are featured in the aritcle.They have experience using NBEMS and have a group, www.wpanbems.org that uses NBEMS with MT63 & Olivia. Last winter Dave & Harry held a webinar about NBEMS. I've attached a copy of the NBEMS webinar presentation. Dave should also be able to forward a copy to you. More information about NBEMS capability is available at: www.w1hkj.com Additionlly, there is Yahoo group, NBEMSham, focusing on NBEMS available at: http://groups.yahoo.com/group/NBEMSham/ It's an interesting technology that seems very easy to use & may have some application, especially on a local basis. 73, Mark, WB9QZB Chicago, IL
