Winlink - Sending Emails over Radio Frequencies (2024)

FAQs

What frequency does Winlink use? ›

2 meter packet uses the 1200 baud rate on these frequencies. 144.93, 145.01, 145.03, 145.05, 145.07, 145.09 and 145.53 MHz. Winlink is a messaging system with services that include email with attachments, position reporting, weather bulletins, emergency relief communications, and message relay.

It can also activate the transmitter on the radio and send the data from the computer out over the airwaves. When an email is posted to the Winlink outbox, the software will automatically send it out to any stations in the area set up as a gateway to the email service.

Using WinLink to Send Email

The maximum attachment size is currently 5MB per message as compared to the 100KB limitation on HF and Packet RMS stations. Refer to the information below for details about specific network settings and procedures for configuring Winlink over AREDN®.

Get on Winlink

WL2K allows hams to send and receive Winlink email using the PACTOR or WINMOR digital mode on their HF radio — or via packet on VHF or UHF frequencies. On HF, you'll need a sound card and software to send via WINMOR, or a separate communications processor that supports the PACTOR family of digital modes.

Technical protocols

PACTOR-I, WINMOR(deprecated), ARDOP, HSMM (WiFi), AX. 25 packet, D-Star, TCP/IP, and ALE are non-proprietary protocols used in various RF applications to access the Winlink network systems.

It is capable of operating completely without the internet--automatically--using smart-network radio relays. Licensed Winlink operators/stations use both amateur radio and government radio frequencies worldwide.

Data Over Radio Applications

Data over radio can be used by simple and complex machines to open and close gates, inform other machines of temperature, pressure, water levels, distance, speed, voltage change, and a multitude of other conditions in applications that are now very common and ever-present.

You load up your Google docs, websites, and email, all using radio waves to connect wirelessly to the internet through WiFi. You see, radio waves are used in many more things than the square boxes that we use to play music and listen to talk shows.

The basic principle is simple. At one end, a transmitter « encodes » or modulates messages by varying the amplitude or frequency of the wave – a bit like Morse code. At the other, a receiver tuned to the same wavelength picks up the signal and 'decodes' it back to the desired form: sounds, images, data, etc.

SYSTEM REQUIREMENTS: Winlink Express is compatible with Microsoft-supported 32- or 64-bit Windows OS, including Windows 7, 8, 10, and 11. It can also be used on Apple Mac and Linux machines using a virtual machine engine or dual boot setup.

How many CMS servers are in the Winlink system? ›

The Winlink system consists of two CMS's (presently) which are hosted in the Amazon cloud (in different Amazon availability zones). All connections to a CMS are managed by another set of servers which balance load and determine health of each CMS.

Besides using RF and Telnet modes, the system will also operate using MESH. The magic happens with Winlink Express when messages are sent using the above modes that reach the main Central Message System (CMS) or the various HF/VUF/UHF Radio Message Server (RMS) gateway stations.

Here is a very boring, but very useful list of frequencies used by the K4CJX WinLink 2000 MBO. Center frequencies: 3618.9, 3620.9, 3621.9, 7070.4, 7072.4, 7073.9, 7075.9, 7076.9, 10121.9, 10122.9, 10123.9, 10125.9, 10126.9, 14064.9, 14065.9, 14069.9, 14071.9, 14072.9, 14073.9 and 14076.9 kHz.

Because of the nature of a ham radio station, it can be set up anywhere, requires no commercial power, is relatively inexpensive, and if one station fails, the rest of the system continues without any interruption. So, the answer is: Yes, ham radio is still a thing.

NOTES: EchoLink can be used on smart phones, tablets, laptops, desktops, HTs, mobile and home station radios. Winlink Express requires a Windows operating system but can be used on laptops and desktops with relative ease.

All GPS satellites broadcast on at least two carrier frequencies: L1, at 1575.42 MHz, and L2, at 1227.6 MHz (newer satellites also broadcast on L5 at 1176 MHz).

That's called S band (2–4 GHz), but we also use X band (8–12 GHz) and the Ka band (27–40 GHz). The earliest widely used DSN frequency was S band. Later added were X band and Ka band, which can send much more data per second. In the future, the DSN will support optical communication in the infrared frequency band.

VOR operates in the 108.0 MHz–117.95 MHz band to provide aircraft avionics ability to determine the azimuth (direction/compass heading) the aircraft would have to fly to the VOR, or the azimuth the aircraft is flying from a VOR.

There are currently only 5 frequencies in 60 Meter that are open to ham radio: 5332 KHz, 5348 KHz, 5358.5 KHz, 5373 KHz, and 5405 KHz. 40 Meter ranges from 7.000 MHz to 7.300 MHz. It is considered by many to be the most reliable long-distance (DX) band, and for that reason often has a lot of traffic.
