Hierarchical levels of the Winlink System
1. Common Message Servers (CMS) - Winlink backbone
2. Internet
3. Nearby Radio Message Server (RMS) - Radio Gateway
4. Client System - Radio, computer with Winlink Express, TNC (or sound card), and you, the end-user

Hierarchical Levels without the Internet

1. Nearby Radio Message Server (RMS) - Radio Gateway, require three which are linked
2. Client System - Radio, computer with Winlink Express, TNC (or sound card), and you, the end-user

Southern US Gateways

The nearest gateways to Sumter County are the three in Marion County (145.030 and one in Citrus County (145.630) which provides us access to the Internet. To the South of us, there is Tampa (145.050) and Orlando (145.070).

Winlink Peer-To-Peer Radio Only

This is the method that has a lot of potential for Sumter County and can be done via simplex or utilizing a local repeater to connect end-users who must be on the same frequency and both are using Winlink Express.

The Internet is not used, all communications by radio
Only the two client stations are involved
100% error-free transmission and file attachments

Winlink Connection Modes

Telnet (Internet)– Non-radio connection through the Internet. Good for training (no radio equipment required) and use if radio is down or network is busy.
VHF/UHF Packet (Local LOS propagation)-

9600 baud – Fast, reliable, range limited and requires
1200 baud – Slower, but can use inexpensive

HF WINMOR - “Poor man's Pactor” Not as good as Pactor, but operates with inexpensive sound card device (SignaLink) speed between Pactor 2 and 3.
HF Pactor 1,2,3, and 4 – Fast and reliable but requires an expensive modem ($1500+).
