3. A typical ham radio digital station is composed of simple components. E-MAIL VIA HAM RADIO Winlink Basic User Overview In order to do e-mail, it is necessary to link to a WL2K Radio Mail Server (RMS) station. The Ham computer is equipped with WL2K Client software. RMS Gateway stations must have internet connection. RMS links to the WL2K Central Mail Server (CMS) Radio Data Interface RMS Gateway Radio Data Interface Client Computer WL2K CMS On Internet

4. The WL2K system has redundant, mirror-image servers connected together on the internet. We call them CMS or Common Message Servers. They are located well-apart around the world and any one of them can easily support the whole WL2K system if one or more should go offline.

11. Winlink 2000: User Software There are currently three principal programs users can use to access the Winlink 2000 system: Airmail Paclink RMS Express

12. Winlink 2000: User Software Airmail: Original program for sending / receiving WL2K messages. Supports HF PACTOR, VHF/UHF Packet and Telnet. Supports peer-to-peer and connections to RMS Gateways. Limited TNC types supported. Simple built in e-mail interface. Setup is less straightforward than newer clients. Contains a catalog of over 700 WX Products and other related info. Contains an interface for real-time GPS reporting. Still in widespread use, especially by the maritime community.

13. Winlink 2000: User Software Paclink: Established program on 3rd generation – very stable Supports HF PACTOR, VHF/UHF Packet and Telnet Wide variety of TNC types supported including AGW packet engine Pop/SMTP e-mail server supports popular client e-mail software Provides multiple users access over a Wi-Fi or wired LAN. Setup is simple

14. Winlink 2000: User Software RMS Express: Newest member of WL2K user software family Supports HF PACTOR, HF WINMOR, VHF/UHF Packet and Telnet Supports RMS Gateways and peer-to-peer connects. Wide variety of TNC types supported, including a generic “KISS” mode. Contains template for over 700 WX and related products. Contains interface for real-time GPS reporting. Setup is simple with automatic program and frequency list updates.

15. WL2K HF MODES NOW INCLUDE PACTOR 1,2,3 – Firmware-based data modems. E-MAIL VIA HAM RADIO How do Hams do that? More expensive ($700+) SCS PTC units provide P1, P2 (up to 8X P1 speed), P3 (up to16X P1 speed.) and P4 (non-ham frequencies) Legacy multimode TNCS (KAM+, PK-232, etc.) support P1. WINMOR – New soundcard-based protocol provides up to 2.5X P1 (500Hz BW) and 10X P1 (1600 Hz BW).

16. WL2K HF MODES NOW INCLUDE WINMOR Sound Card TNC E-MAIL VIA HAM RADIO How do Hams do that?

17. WINMOR “Virtual TNC” Screen Capture: 3 Carrier 16QAM ”+” 3 Carriers decoded OK 16QAM Circular Constellation (White Gaussian Noise @ 5dB) Each pixel = 1 symbol Receive Level Tuning Offset Relative decode Quality 1 KHz waterfall

18. WINMOR “Virtual TNC” Screen Capture: 15 Carrier QPSK “M” recovery after Summation (memory ARQ) “m” no decode, Good ID (added to summation) “-” no decode, poor ID match (not added to summation) “+” decoded OK QPSK Constellation (heavy fading) Each pixel = 1 symbol Frame Type Connection State Bytes Received 2KHz waterfall
