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.
