NEW EMCOMM SOFTWARE FOR WINDOWS
The NarrowBand Emergency Messaging System (NBEMS) development team announced earlier this week that a Windows NBEMS software suite for beta testing is now available. NBEMS for Windows is a suite of software programs designed for point-to-point, error-free emergency messaging up to or over 100 miles distant.
According to developers Skip Teller, KH6TY and Dave Freese, W1HKJ, the NBEMS system is designed primarily for use on VHF and up, or on HF with Near Vertical Incidence Skywave (NVIS) antennas. The system uses the computer soundcard as the modem. Other than a simple interface connection between the computer and transceiver, no additional hardware is needed. Composing and sending emergency messages on NBEMS is no more difficult than sending e-mail via the Internet. All forwarding is done by stations manned by live operators on both ends who can confirm that a frequency is clear locally, or negotiate a frequency change to avoid causing interference.
The NBEMS software can also be used for daily casual communications on PSK31, PSK63, RTTY or MFSK16 and is capable of sending flawless, high resolution, passport photo-sized color images in less than 10 minutes over any path that can sustain PSK250 without excessive repeats.
