Introduction to RTTY: A Guide to Getting Started

Introduction

What is RTTY?

Radio Teletype, or RTTY, is one of the oldest digital modes in amateur radio, allowing for the transmission of text over the airwaves. Developed in the early 20th century, RTTY was originally used in telegraphy and military communications before becoming a staple in amateur radio. It is a simple yet reliable way to send and receive messages using a combination of two tones to represent binary data, making it accessible to operators of all levels.

Why Choose RTTY?

RTTY has stood the test of time, remaining popular among amateur radio operators for several reasons. First, it’s easy to set up, even for those who are new to digital modes. Unlike voice modes, RTTY cuts through noisy environments and works well even when conditions aren’t ideal. If you enjoy contesting or DXing (chasing long-distance contacts), RTTY is a great mode to explore. Its straightforward operation and reliability make it a go-to choice for casual operators and competitive contesters alike.

Who is This Guide For?

This guide is designed for both beginner and intermediate ham radio operators who want to get started with RTTY. Whether you’re setting up your first RTTY station or looking to fine-tune your setup for contests, this guide will walk you through the essential equipment, setup steps, and operating procedures. By the end, you’ll be ready to jump into the world of RTTY and enjoy its many benefits.

Understanding the Basics of RTTY

What is RTTY?

RTTY, or Radio Teletype, is a mode of communication that transmits text via radio waves by encoding characters into binary data. It was originally used for telegraphic communication in the early 1900s, but today, it’s widely embraced by amateur radio operators. RTTY works by sending two distinct tones—known as “mark” and “space” frequencies—that represent binary 1s and 0s. These alternating tones allow the transmission of characters, making RTTY one of the simplest and most reliable digital modes available.

How RTTY Transmits Data

RTTY uses a method called Frequency Shift Keying (FSK) to transmit data. This technique shifts between two frequencies—mark (high tone) and space (low tone)—to represent binary code. Each character typed is converted into a series of bits, typically 5 bits using the Baudot code (an early form of digital text encoding). Each bit is either a mark or a space, and when transmitted, the receiving station decodes these tones back into characters. This is what allows RTTY to transmit text messages over long distances, even in noisy conditions.

Key Terms:

• FSK (Frequency Shift Keying): The modulation method that shifts between two tones to represent data.
• Mark & Space: The two frequencies used in FSK; mark is the higher frequency, and space is the lower.
• Baud Rate: The speed at which symbols are transmitted. Standard RTTY uses a 45.45 baud rate, which corresponds to about 60 words per minute.

RTTY Frequencies

RTTY signals are commonly found on the HF bands (High Frequency). Here are the key frequencies where RTTY activity is popular:

• 80 meters: 3.58–3.62 MHz
• 40 meters: 7.04–7.06 MHz
• 20 meters: 14.08–14.10 MHz
• 15 meters: 21.08–21.10 MHz
• 10 meters: 28.08–28.10 MHz

These are starting points, but actual frequencies can vary depending on the region and propagation conditions. When searching for RTTY signals, tune around these frequencies and listen for the distinct high-pitched tones that characterize RTTY transmissions.

Why RTTY?

Many operators favor RTTY because it is resilient. Unlike some digital modes that may drop out under noisy conditions or require a lot of bandwidth, RTTY remains reliable in most scenarios. It also operates without requiring as much power or complex modulation as other modes like Single Side Band (SSB), making it ideal for contesting or when working in areas with poor propagation.

Understanding the basics of how RTTY works and where to find it on the bands will prepare you for setting up your station and making your first contact!

Equipment and Software You Need

Essential Hardware

To get started with RTTY, you don’t need a lot of specialized equipment, but there are a few key components you’ll need to get set up properly:

• Transceiver: A radio capable of transmitting and receiving RTTY signals is your most important piece of equipment. Many modern transceivers have built-in digital mode capabilities, including RTTY. If your radio doesn’t have built-in RTTY support, it will still work as long as you have a way to connect it to your computer.
• Computer: Almost all RTTY operation today uses software on a computer to decode and encode the digital signals. Your computer will act as the interface between your radio and the digital world. Any standard desktop or laptop will work as long as it meets the basic requirements of the software you choose to run.
• Modem (TNC) or Sound Card Interface: If your transceiver doesn’t have built-in RTTY functionality, you’ll need a device to convert the digital signals from your computer into audio signals that the radio can transmit and receive. There are two main options:
  • Terminal Node Controller (TNC): A specialized piece of hardware that handles encoding and decoding digital signals.
  • Sound Card Interface: An external sound card or digital interface (like a Signalink USB) that connects your radio to your computer’s sound card. Many operators use this option because it’s more versatile and affordable than a dedicated TNC.

Choosing the Right Software

There are several software options available that make operating RTTY simple and efficient. Below are some popular choices, along with the platforms they support:

• FLDIGI (Windows, Mac, Linux): One of the most popular and versatile digital mode applications. It supports multiple digital modes, including RTTY, and is free to use.
• MMTTY (Windows): This is a dedicated RTTY software program that has been around for years. It’s widely used in contests and is known for its simple, efficient interface.
• Ham Radio Deluxe (Windows): A comprehensive software package that includes digital mode support, logging, and rig control. It is a paid program but offers a lot of functionality in one package.
• MultiPSK (Windows): Another option that supports multiple digital modes, including RTTY. It’s highly customizable but may be a bit more complex to set up.

Each of these programs allows you to connect your radio to your computer and start decoding RTTY signals. Most of them are free or offer free versions, making them accessible for any operator.

Optional Accessories

While you can get by with the basics, a few accessories can enhance your RTTY experience:

• CW Interface: If you’re planning on using other digital modes, having a CW interface may be useful for faster operations, especially in contests.
• External Sound Cards: Many operators use external sound cards, like the Signalink USB, for improved audio quality and better isolation between your radio and computer.
• RTTY Filters: Some transceivers come with built-in digital filters that can help narrow down the signal and reduce interference. If your transceiver doesn’t have these, you can add an external filter for better reception.

Setting Up Your RTTY Station

Basic Setup Steps

Setting up an RTTY station involves connecting your transceiver, computer, and either a modem (TNC) or a sound card interface. Here’s a step-by-step guide to get everything connected and running smoothly:

1. Connect Your Transceiver to Your Computer
   • If your transceiver has a USB port for digital modes, you can simply connect it to your computer with a USB cable. Many modern transceivers, like the Icom IC-7300, have built-in sound cards, so the USB connection is all you need.
   • If your radio doesn’t have built-in digital capabilities, you’ll need a sound card interface, such as a Signalink USB, to connect your radio to your computer. This will convert the audio signals between your radio and computer’s sound card.
2. Install Your RTTY Software
   • Once your hardware is connected, install your chosen RTTY software (such as FLDIGI or MMTTY). Most software options have clear setup wizards to guide you through the process.
   • Make sure your software is configured to use the correct audio input and output devices. If you’re using a USB sound card interface, select it in the software’s settings under the audio options.
3. Connect the Radio to Your Software
   • In your software, select the correct mode for RTTY (also called Baudot in some software). Set the baud rate to the standard 45.45 baud, which is typical for most RTTY communications.
   • Configure the software to control your transceiver, if you’re using rig control (CAT). This allows your software to automatically tune your radio, change frequencies, and transmit.

Tuning for RTTY Signals

Once your hardware and software are connected, it’s time to tune into an RTTY signal:

1. Set Your Radio to Upper Sideband (USB)
   • Unlike most voice modes on HF, RTTY uses Upper Sideband (USB), even on bands like 40 meters where voice typically uses Lower Sideband (LSB). Double-check that your transceiver is set to USB before attempting to decode any signals.
2. Tune to a Known RTTY Frequency
   • Use the band plan to find active RTTY frequencies. Start by tuning to frequencies where RTTY is commonly found, such as 14.080 MHz on 20 meters.
   • Look for the characteristic “warbling” sound of an RTTY signal. It’s distinct and easily recognizable once you hear it.
3. Fine-Tune the Signal
   • Use your software’s waterfall display (if available) to fine-tune the signal. This display will show the RTTY signal as two vertical lines—adjust your frequency so those lines are centered.
   • If your transceiver has an RTTY or narrow filter option, engage it to reduce interference from nearby signals.

Adjusting Transmit and Receive Levels

Proper audio levels are critical for clear RTTY communication, both for transmitting and receiving:

1. Receive Levels
   • Start by adjusting the audio levels in your software so that incoming signals are strong enough to decode but not too loud. Many programs have an audio input meter—aim for a level that’s in the green but not peaking into the red.
2. Transmit Levels
   • When transmitting, you’ll want to avoid overdriving your signal, which can lead to distortion and make your signal difficult to copy. Adjust your output levels in the software to ensure a clean transmission.
   • A good way to check your levels is to monitor your signal with a second receiver or ask another operator to give you a signal report.

With everything connected, tuned, and adjusted, you’re now ready to start making contacts using RTTY! Up next, we’ll dive into the operating procedures to get you on the air smoothly.

RTTY Operating Procedures

Calling and Answering CQ on RTTY

One of the most important skills to master when using RTTY is how to call CQ and respond to other operators. Let’s break it down:

1. Calling CQ
   To call CQ (which means you’re seeking a contact), use a simple and clear message. In RTTY, you typically use macros, or pre-set messages, to simplify the process. A common CQ message looks like this:

css

Copy code

CQ CQ CQ DE [YOUR CALLSIGN] [YOUR CALLSIGN] CQ CQ CQ K

1. CQ CQ CQ: This is the call for any station to respond.
2. DE [YOUR CALLSIGN]: “DE” means “from,” followed by your callsign. Repeat your callsign to make sure the other operator copies it correctly.
3. K: This means you’re inviting a response.
4. Responding to a CQ
   When you hear a CQ, the response follows a similar structure. Here’s how you reply:

css

Copy code

[THEIR CALLSIGN] DE [YOUR CALLSIGN] [YOUR CALLSIGN] K

2. Start with the other station’s callsign to indicate you’re responding specifically to them.
3. Use “DE” followed by your callsign, then send your callsign again for clarity.
4. End with “K” to let them know it’s their turn to respond.
5. Repeat If Necessary
   Due to poor band conditions or interference, signals can sometimes be weak or garbled. Be prepared to repeat key information like callsigns or signal reports if needed. It’s better to repeat a few times to ensure the contact is successful.

Exchange Formats

RTTY exchanges typically include your callsign, a signal report, and your location. Let’s break down a basic QSO (contact) exchange:

1. Your Signal Report (RST)
   • The standard RST (Readability, Signal strength, Tone) reporting system is used in RTTY, with the tone part usually omitted (since RTTY doesn’t use a variable tone). RST reports on RTTY are typically something like “599,” where:
     • 5 indicates perfect readability.
     • 9 indicates a strong signal.
     • The third “9” represents tone, but it’s usually not relevant for RTTY, so it’s often left as “9” by default.
2. QTH (Location)
   • You’ll often exchange your QTH, which is the shorthand for your location (usually your city or grid square). This is common in non-contest exchanges where operators enjoy learning more about where others are operating from.
3. Additional Info
   • In casual conversations, operators may also exchange names, weather conditions, or station details (like transceiver model or antenna type).

Here’s an example of a typical RTTY exchange:

css

Copy code

[YOUR CALLSIGN] DE [THEIR CALLSIGN] UR 599 599 QTH [YOUR CITY] NAME [YOUR NAME] K

Using Macros

Macros are a key feature of most RTTY software, allowing you to send pre-written messages with the click of a button. This makes communication faster and more efficient, especially in contests or busy band conditions.

1. Setting Up Your Macros
   • Most RTTY software allows you to customize macros for common exchanges like calling CQ, sending your callsign, giving a signal report, or saying 73 (best regards).
   • Set up macros for:
     • CQ Call
     • Exchange of Callsigns and Reports
     • Closing the QSO with “73”
2. When to Use Macros
   • Use macros to speed up repetitive parts of the conversation, but don’t rely on them entirely. Be ready to manually type if conditions require flexibility or if a conversation becomes more detailed.

RTTY Contesting

RTTY contesting is a fun way to sharpen your skills and rack up contacts quickly. The exchange format in contests is often shorter and more standardized. Here’s how it typically works:

1. Contest CQ
   • You call CQ, and stations respond quickly with their callsign and report. A typical contest exchange might include:
     • Signal Report (RST)
     • Serial Number (a unique number you assign to each contact, starting with 001 and increasing by one with each new QSO).
2. Quick Exchanges
   • Contest exchanges are brief to maximize contacts. You may only exchange RST and serial numbers before quickly moving on to the next contact.
3. Logging Contacts
   • During a contest, log each contact carefully using contest logging software. Be sure to include the other station’s callsign, signal report, and serial number.

Common RTTY Mistakes and Troubleshooting Tips

Even though RTTY is a straightforward mode, there are some common mistakes that operators encounter, especially when starting out. Here are some typical issues and tips on how to troubleshoot them effectively.

1. Overdriving Audio

The Issue:
One of the most common problems in RTTY operation is overdriving the audio signal when transmitting. This happens when the audio input level to the radio is set too high, leading to a distorted and unreadable signal on the other end.

How to Fix It:

• Adjust Audio Levels: Use your software’s audio output settings to lower the audio going to your transceiver. Most RTTY software, like FLDIGI or MMTTY, has audio meters that help you monitor your levels.
• Monitor Your ALC (Automatic Level Control): Many transceivers show an ALC meter when transmitting. If the ALC is showing high levels, you need to reduce your audio input. The ALC should show only minimal movement during transmission.

Prevention Tip: Always do a test transmission and ask for a signal report from a fellow operator or use a second receiver to monitor your own signal.

2. Incorrect Baud Rate or Mark/Space Settings

The Issue:
RTTY relies on specific baud rates and mark/space frequencies. If these settings are incorrect in your software or radio, you won’t be able to properly decode the signals, or your transmissions may not be readable by others.

How to Fix It:

• Set Baud Rate Correctly: For most amateur RTTY operations, the standard baud rate is 45.45 baud. Double-check this setting in your software.
• Mark and Space Frequencies: The standard mark/space frequencies for RTTY are 2125 Hz for mark and 2295 Hzfor space. Make sure your software is set to use these frequencies, or manually tune them if needed.

Prevention Tip: Always check your baud rate and mark/space settings before a QSO. Most software will allow you to save these as default settings to avoid having to configure them each time.

3. Interference Issues

The Issue:
Radio Frequency Interference (RFI) can cause unwanted noise in your RTTY signal, leading to difficulty in decoding signals or poor transmission quality.

How to Fix It:

• Use Proper Grounding: Ensure your station is properly grounded to reduce RFI. This includes grounding your transceiver, computer, and any other equipment.
• Reduce Power: Sometimes reducing your power output can help minimize interference, especially in areas with a lot of electrical noise.
• Check for Sources of Interference: Common household devices like power supplies, computers, or even LED lights can generate RFI. Turn off unnecessary devices or move your radio equipment away from sources of interference.

Prevention Tip: Use ferrite beads or RFI filters on your cables to minimize interference and keep your station as electrically isolated as possible.

4. Decoding Issues

The Issue:
Sometimes, RTTY signals will be garbled or difficult to decode. This can be caused by a variety of issues, including weak signals, improper tuning, or poor software configuration.

How to Fix It:

• Fine-Tune the Signal: Use your radio’s tuning features to precisely dial into the RTTY signal. Most software will have a visual waterfall display that helps you zero in on the signal. Adjust the tuning until the signal is centered in the mark/space lines.
• Use Filters: If your radio has digital filters, activate them to reduce noise and narrow the bandwidth around the RTTY signal. This will help focus on the signal you want to decode.
• Adjust Software Settings: Ensure that your software’s mark and space frequencies are correctly set, and adjust the software’s squelch or noise reduction features if needed.

Prevention Tip: Before jumping into a QSO, monitor the band for a few minutes to practice tuning into different RTTY signals and adjusting your filters.

5. Poor Propagation Conditions

The Issue:
Poor propagation can make RTTY signals weak or fade in and out. This is especially common during solar storms or when the bands are not in great shape.

How to Fix It:

• Be Patient: If propagation is poor, sometimes all you can do is wait for better conditions. Signals may fade in and out, and it can take time to make a solid contact.
• Try Different Bands: If one band isn’t working, try switching to another. Higher frequencies (such as 15 or 10 meters) work better during daytime, while lower frequencies (such as 40 or 80 meters) are often better at night.

Prevention Tip: Always check propagation conditions before operating. Websites like DXmaps or solar activity monitors can give you a good sense of band conditions for the day.

Advancing Your Skills in RTTY

Once you’ve mastered the basics of RTTY and gained some experience, it’s time to take your skills to the next level. RTTY has many advanced techniques and opportunities for you to explore, from experimenting with new methods to participating in community groups and earning awards. Here’s how you can advance your RTTY operating.

Experimenting with Advanced RTTY Techniques

As you become more comfortable with RTTY, you can start experimenting with advanced techniques to improve your performance and expand your understanding of the mode.

1. Split Operation
   • What It Is: Split operation is when you transmit on one frequency and listen on another. This is especially useful when trying to work a busy DX station (a station in a distant location) that is receiving numerous calls.
   • How to Do It: To use split operation, you’ll need a transceiver with split mode capability. Set your transmit frequency slightly higher or lower than the calling frequency to avoid interference. Many software programs also support split operation, making it easier to manage.
   • Why It Helps: Split operation allows you to make contacts in busy situations and helps you avoid competing with multiple stations on a single frequency.
2. Using RTTY on VHF/UHF
   • Expanding Beyond HF: While RTTY is most commonly used on HF bands, you can also experiment with VHF/UHF for local contacts or even satellite communications. The principles remain the same, but propagation and equipment requirements change.
   • Getting Started: You’ll need a VHF/UHF transceiver capable of digital modes, and the setup will be similar to HF RTTY, except you’ll be working with different frequency bands.
3. Faster Baud Rates
   • Exploring Higher Speeds: While most RTTY communication uses a baud rate of 45.45 baud, some operators experiment with faster baud rates (such as 75 baud) to increase the speed of transmission.
   • Considerations: Faster baud rates can make communication quicker, but they require better signal conditions and may not be as reliable as the standard 45.45 baud. Test out higher speeds in good conditions and during casual QSOs to see if they work for your setup.
