  2. Digital Radio And Emergency Communications 2

  3. Why Digital?? Voice, Morse or Radiograms quite often will not do for complex messages 3

  4. Why Not??  Text Only  Somewhat Slow  Translation Often Required  Prone to Error  No Permanent Record 4

  5. What Do We Do??  Winlink!!  Preferred by many  Endorsed by ARRL/ARES  Accepted by many EMCOM users  Endorsed by GAARES  Proven by many years of use 5

  6. What Is Winlink??  WL2K is not a computer program itself but a system of applications compatible with email  Allows accurate transfer of messages within a reasonably short time frame  Uses internet whenever available  Uses radio when non-radio path is not available  Maintained by a team of dedicated volunteers 6

  7. Winlink  Original purpose to provide long range radio system for amateurs without access to email  First used by ham boaters and RVers also missionaries and medical providers in Third World Countries  Adopted by EMCOM for partial backup of email service during local comm outages 7

  8. Winlink Applications  Winlink Express (Client Program)  Telnet (Internet)  RMS Packet (VHF/UHF Digital Server)  RMS (Radio Message Server)  CMS (Central Message Server Internet Only) 8

  9. Winlink Express  Radio and Internet Capable Program  Less expensive alternative to Pactor  Many qualities similar to email  Requires computer, interface and radio 9

  10. Central Message Server  Four CMS Sites Worldwide  All four sites are continuously synchronized  Telnet (Internet) accessible only 10

  11. RMS Packet  Stand alone program to connect radio packet links to the internet  Gateway between VHF/UHF packet and internet  Requires radio, TNC, computer and internet for access 11

  12. RMS Relay  Serves as companion program to RMS Packet  Provides temporary storage of local traffic in the event internet access is lost  Provides local routing of messages during internet outage 12

  13. RMS Pactor  Uses Proprietary modem  Connects radio links to CMS  Utilizes radio and modem  Modem and license pretty expensive 13
