Digital Training Update”Every Station a Digital Station” • NEDTM1 - Started 28 MAY 2013 • That’s the “Northeast Division Digital Training Multi-Mode Net One” • NCS Stations AFE2DM (AFA2HV), AFE3EC (AFA3RH) • Frequent contributors AFA1DI, AFA2QD, AFA2DO • The purpose of the net is to advance the digital capabilities of Northeast Division AFMARS members • Typically 10 to 15 stations per net • 17 sessions to-date • Sound card mode set-up, use of MT63, use of Winlink 2000 and modem modes covered in detail or introduced since May.
Digital Training Update”Every Station a Digital Station” • What does it mean to be a digital station on a division net? • This is the ability to relay a message to the recipient via digital modes • Almost all traffic on the nets are net summaries to AFA1VY • This requires Winlink 2000 to make the relay • This can be accomplished with a sound card mode called WINMOR or with a PACTOR modem • WINMOR (FREE!) is packaged with RMS Express (FREE!) and available on the winlink.org website • PACTOR 1 modems include many of the older Kantronics and AEA PK 232 models • PACTOR 1-4 modems are available from SCS GMBH. They cost a lot but are fast! • If you would like to take traffic on the division nets this is what you need • Hardware needed for RMS Express/WINMOR is a sound card interface (cheap!)
Digital Training Update”Every Station a Digital Station” • Recommended Level of Capability for Every AFMARS Member • Hardware: • Sound card mode interface between radio and computer • Related cabling • Software: • RMS Express (with included WINMOR software modem) for Winlink 2000 system access • MT63 capable software such as FLDIGI, DM780, MultiPSK, MixW etc (there are many) • Currently FLDIGI has the advantage in accurate reproduction of formatted iinformation spaced by tabs and keyboard spaces • Advanced Capability • Hardware: • SCS PACTOR 3 or PACTOR 4 (The Dragon) capable modem • Software: • FLDIGI with suite of helper applications
Digital Training Update”Every Station a Digital Station” • ECOM and Digital Modes – How will we use it? • Good question. Operational concept still being developed. • Likely that it will be used to send error free traffic of length unsuitable for voice communications • Images as attachments via WL2K • Spreadsheets • Other documents • ECOM nets will likely be mixed mode where initial contact is established by voice and traffic passed with a digital mode if needed. • Challenges • Interoperability with other MARS services • Navy-Marine Corp MARS = MT63 (√) • Army MARS = M110A (x) • Interoperability with ANG units M110B and other modes • Expensive modems • Potential for proprietary software issues with some hardware
