2 Global Radio System for EmComm usage
3 Example of EmComm usage Rescue of the Bounty by WinLink Destruction during Hurricane Sandy 140 km east of USA-eastcoast, Fall 2012 Version
4 Example of EmComm usage (II) Distress call via Maritime mobile Net (HF) and satellite phone failed Cpt. Robin Walbridge, KD4OHZ sent an E- Mail to US Coast Guard via PACTOR on HF (WinLink) 14 out of 16 crew members were rescued KD4OHZ and another crew member lost Version
5 Example of EmComm usage(iii) Hurrican Cathrina 2005 Amerikan Red Cross and Hams established a HF Network (HFLink) in split mode Mode: Automatic Link Establishment (MIL STD ) h w Version
6 Requirements of digital modes for EmComm Communication with non-ham stations (AtC, AtA) , SMS etc. Asynchron Communication Availability independent of QTH (global) Internet connection to adress non-hams Balance robust/fast/cheap Less Hardware requirements as possible Error free (error correction) Version
7 Requirements of digital modes for EmComm (II) easy to handle (intuitiv) Interoperability Adaption of international standards (eg. WRC) Redundant and decentral network structure Version
8 Systems / networks WinLink 2000 jpskmail SCSmail RFSM 2400/8000 Version
9 WinLink network for hams and sailors (HF/VHF/UHF); call@winlink.org global availability (established infrastructure) Redundant and synchron CMS (failsafe through intercontinentally redundancy) Error correction procedures Bulletins (e.g. weather, keps, broadcasts) different modes (interoperability): PACTOR,WINMOR, ALE, PR, D-STAR, (HamNet) Version
10 robust soundcard modes (WINMOR, PR) high data transfer rates (PACTOR III and IV) up to 25 on HF File-recovery Peer-to-Peer (P2P) Automaticaly forward via HF if internet loss occures (ROWN) Version
