• Works Transparent with Internet E-Mail
• Callsign_at_winlink.org
• Must be registered
• Airmail is the Client User Program, by Jim
  Corenman KE6RK
• www.airmail2000.com
• Public PMBOs on HF (43)
• Special ARES PMBOs for Emergency Traffic
• Non-Public
• Using MS Outlook or MS Outlook Express, the
  Paclink mini-email server can replace a network
  of computers (behind a router) as a transparent
  substitute for normal SMTP mail.
• WL2K uses no external source for sending or
  receiving Internet email.
• It is a stand-alone function which interacts
  directly with the Internet rather than through
  any external Internet service provider.

Bulletins

• Bulletin Distribution
• On-demand from a Catalog Listing
• Over 700 available weather, propagation, and
  information bulletins, including, instructions
  for using the system, World news, and piracy
  reports
• Can contain basic text, graphic fax or satellite
  images, binary or encoded files like GRIB or WMO
  weather reports
• Local processing is used to re-process images to
  sizes suitable for HF Pactor transmission
• Prevents bulletin duplication and automatically
  purges obsolete time-sensitive weather bulletins
  and replaces them with the current version
• System also has the ability to contain bulletins
  with attachment information which is local to
  each participating PMBO
• Especially useful for the non-public ARES PMBO
  which may house valuable procedural information
  or complex instructions which may be needed by
  specific agencies in a community emergency

What is WL2K?
DCC 2003

• Introduced in 2000 (DCC 2000) WL2K is a modern
  software implementation of a Global ham message
  system capable of conventional BBS functions with
  significant extensions for the Mobile user.
• Biased toward the mobile user.
• Conventional BBS functions with routing and store
  and forward for radio and E-mail messages.
• No Home BBS designation required (global
  message mirroring)
• Optimized to capitalize on Internet forwarding
  when possible
• On demand WX products and other Web information.
• E-mail with text/compressed binary attachments
• Position reporting and request from radio and
  Internet
• Currently 4300 Users (HF Pactor, Packet, Telnet,
  Web) delivering over 150,000 messages per month
  by 36 PMBOs.

Motivation for Telpac and Paclink
DCC 2003
WL2K has been very well accepted by the mobile HF
community Many requests to expand local WL2K
coverage (VHF/UHF) Emergency communications Smal
l portable terminals Two obstacles for widespread
VHF/UHF expansion The standard PBMO
setup requires a considerable
computer, radio equipment and synchronized data
base. Telpac provides a simple Telnet to Packet
bridge The user client program has to work with
most available TNCs and interface with existing
E-mail clients. Paclink provides a user client
that meets these objectives
14
Telpac Paclink
Development Approach
DCC 2003
Leverage existing standardized interfaces
protocols Existing WL2K Telnet Servers via
Internet/Telnet Standard TCP communication
between components Standard mail format and
server protocols MIME message storage POP3
and SMTP servers Capture TNC drivers using a
standardized TCP interface AGW Packet
Engine Use modern development environment and
tools for improved productivity and reduced
support Telpac VB6, Paclink VB.NET

The AGW Packet Engine with Telpac and Paclink
DCC 2003
By George Rossopoulos, SV2AGW Standardized TCP
interface supports most TNCs Using KISS
mode. Supports sound card TNCs (1200 9600
baud) Shares TNCs across applications
Paclink, Telpac, BBS, APRS, Terminal,
Monitor Allows remote operation via TCP link
TNCs may be separated from application

Telpac and Paclink Applications
DCC 2003
Telpac as a conventional BBS for Last Mile
wireless connectivity Paclink as an end user
client for BBS access (WL2K, FBB etc) Paclink as
the an emergency radio link for Internet E-mail
Paclink provides the radio connection to a
WL2K Telpac node Emergency field operators
use their existing E-mail client but
with a radio account instead of default
account Multiple operators can share a
single Paclink and its TNCs/radios Paclink
Paclink transfers (keyboard or via E-mail
clients)
