The Original Morse Transceiver!

It's a ZERO Plus! Just a ZERO with the added feature of a built-in transceiver! Does EVERYTHING a ZERO does, and 40 meters QRP as well!

Introduced in 2020, this was the beginning of the Morse Revolution! Improved numerous times over the years of its life, it continues to be popular and at a very attractive price as a transceiver and computer in a small, lightweight, and portable low power communications system running off of 12V. Based on many customer reviews, emails, and phone conversations, we can claim to have the best decoder in the universe, backed up by hundreds of hams around the world who have tested it against everything out there!

Available in new and refurbished models

Refurbished DMX-40's are in excellent "like new" condition, with any scratched panels replaced. Visible damage is essentially non-existent or difficult to find.

There is a limited supply of the refurbished DMX-40's available, and more become available from time to time. If you see "SOLD OUT" when you visit our Refurbished product page then check back another time.

DMX-40 Overview

The DMX-40 comes with its own keyboard, protective lid, touch-screen cleaning cloth, and a screw-adaptor plug for connection to a 12 volt battery. It is a mere 11 oz of integrated electronics, including three powerful microprocessors, plus a 3-watt QRP transceiver. One microprocessor is responsible for the graphical user interface (GUI), while the other handle the many tasks required to produce an amazing experience for the user. No computer required - built in! All you need is a 12V power source, an antenna, a powered speaker or headphone, and the included keyboard and you are ready to join the CW revolution!

World’s Best CW Decoder! Decodes in Noise!

We are not just blowing our own horn here: it is our customers who tell us this, based on thousands of hours with hundreds of locations and users all over the globe, who have compared the DMX-40 decoder with everything else out there! The tell us nothing beats it! The decoder is based on a combination of analog and digital signal processing to separate the signal from the noise, and can on occasion decode a signal you can’t even hear under the noise!

2 in 1: Base Station Companion & QRP Transceiver

The DMX-40 is a unique 2-in-1 product: an intelligent decoder and encoder for your base station - we call it External Mode - and a built-in QRP transceiver for 40 meters. In External Mode, augmenting your main transceiver, it can operate on any band your transceiver operates on. In QRP stand-alone transceiver mode, it works only 40 meters. The accessory External Transceiver Cable Assembly is available to simplify the connection to an external transceiver.

Powerful yet Easy to Use GUI

Equipped with over 10 unique features found on no other transceiver on the market, at any price, along with its color touchscreen GUI, extensive help menus, powerful computer automation - essentially a PC and a transceiver in a single box - and 28 different graphic screens, the DMX-40 offers you more than anything else on the market, and is still small and lightweight. It comes with a protective lid, and many accessories are available.

Learning Code? Or just Texting?

The DMX-40 is the absolute best training tool for learning Morse code. Utilizing "Cognitive Association" for learning to hear incoming code and translating each character and word automatically in your head happens after only a few months by listening and watching the code appear translated into text on the LCD. Of course you are already doing this - so there is zero work involved - just happens: your brain learns. Our customers tell us after a few months, they start thinking the character in their mind before it shows up on the screen. Effortless learning!

For sending, use the key to send to the decoder, in Receive Mode. The decoder processes this as if it is another station, and tells you what it thinks you are sending, and the speed you are sending at. Much better than just listening to your code. And of course you can hear the code as well on the DMX-40 headphone out.

Great Technicians: Get on HF!

The DMX-40 is the perfect solution for technician class licensees for getting on the HF bands, without having to learn CW first! Start out by merely texting, and using the built-in QSO automation, and grow from there, using our powerful RPL (Rig Programming Language) to customize the rig to your specifications!

Give Your Teen Something Fun!

The DMX-40 is great for teenagers! Get them off their social media, and onto World Media, via ham radio! It will train their brain from the crazy thinking today into a strong, logical thinking process, and it will be tremendous fun, looking for that contact in a distant country, or finding a friend in Europe, South America, or the tropical islands!

How About Advanced Hams?

You might think that a product like the DMX-40, which was designed for emergency situations (hams use CW to get out in emergencies because it gets through when other modes don’t) would not provide anything useful for an advanced ham operator. WRONG! Many operators can copy 15 to 20 WPM but can’t copy 30, for example. Some have tried to learn CW but have failed, for many reasons. Others have physical limitations that make it difficult to use a key. The DMX-40 provides a solution for all of these cause and more. The powerful RPL microprogramming language enables an advanced ham operator to extensively customize the automation of the DMX-40 for contests, net control, and general operation according to their particular operating style.

DMX-40 Summary

The DMX-40 has something for everyone! At a very affordable price, and an even more affordable price for an almost new Refurbished unit! You can’t get features like this anywhere else, and the price is a great inflation fighter! The DMX-40 price has survived the Biden Inflation and remains at the same price it was at in 2019!

KEYBOARD IS INCLUDED, as well as a small set of wired earbuds!  Also check out our DMX-40 accessories!

NOTE:  The DMX-40 DOES NOT SUPPORT PLUG-IN BAND BOARDS!
