Multi-Band QRP Portable Computer Plus Transceiver!
Check out the MMX Bundles below!
NOTE: while the receiver in the MMX can tune outside of the amateur radio bands, the transmitter is restricted to the frequencies allocated by the FCC for amateur radio operation. In addition, by entering your license, the frequencies may be additionally limited based on the available frequencies allocated for your license level.
The MMX Multi-band Morse Code Transceiver is the evolution of the DMX-40 Morse Code Transceiver,and includes the keyboard and a small pair of wired earbuds! It has the same industry-leading decoder, the same high sensitive SDR receiver, 10 frequency memories per band, RPL microprogramming for custom automation, and more. However, what is added is a band board plug-in system that supports up to 3 bands. Currently, the supported bands include 80, 40, and 20 meters. You can purchase a single band MMX, and add other bands later, purchase a dual band MMX, and add the third band later, or even get all three bands on your initial order!
Specifications are similar to the DMX-40+, such as receiver sensitivity of -119 dBm. Power output is highest on 40 meter, and slightly lower on 80 and 20 meter bands, as listed in the Specifications tab in the right column.
Better, Easier, Relaxing QSO's at Higher Speeds!
Do you need help decoding those fast senders? Do you want a less stressful QSO? Not only do we help you decode with the best decoder in the industry, but you will gradually learn to do so as well by way of cognitive association! For sending, you can use a straight key, the built-in keyboard to Morse system with automatic station ID's and hand-offs, auto-CQ and station calls, automatic capture of the other station's call sign, plus the powerful RPL language for microprogramming to customize of the automation or create your own automations. And, you can get help and practice sending using the build-in decoder to listen to your keying in receive mode. It will treat you as "just another station" and decode your signal, give you your speed, and tell you what other stations would think you had sent. Great key training! And don't forget to start by pressing the Space Bar to restart the decoder before you begin keying!.
Another stress reducer! The built-in typing speed test function sets your maximum transmit speed to match your typing speed! This means that - even if the other guy can type or send at 35 WPM, but you can only type at 22 WPM, that is how fast you will go, enabling you to have time to partially fill the type-ahead buffer so you can relax and edit your keyboard mistakes, and have a little time to think about what you want to say next. A great stress reducer. Of course if the other station is sending at a lower speed, your MMX will match them so they can decode you!
Talk about stress reducing, the automatic capture of the other station's call sign is a great one! It automatically appears in the CCS button (CCS is Captured Call Sign), and is used for the automatic station ID's and hand-offs. No more quick scribbling to write down their call sign! Or typing station ID's over and over. Even a Handle, QTH, Rig, Antenna macro built-in so you can send that info with a single keystroke!
If you want to use a paddle or iambic key, an external keyer is required to convert your key to straight key or "pure Morse" output to feed into the MMX.
So, up your game! Get an MMX to go with you for a great experience in QRP with a lightweight powerful computer plus QRP transceiver! Great for POTA, SOTA, etc. Or, get an MMX attached to your station using our External Transceiver Cable Assembly to make it easy and neat to connect and integrate your station and the MMX as your decoder and encoder. You can also just use the MMX as a decoder, with no keyboard by pressing the status line to restart the decoder

Below are two video links. The first is a long open box to QSO live demo via Coffee and Ham Radio on YouTube. Note that the MMX is accidentally placed into CTX mode during much of the session (and thus can't decode human code, or HCW). I finally noticed that, and after that, things went a lot better!
And here is a look inside the MMX. Note: What comes with the MMX is misrepresented in this video. Only the keyboard, cleaning cloth, and power adaptor come with the MMX, but otherwise, pretty accurate:
Also, for more information, read the DMX-40 description. The MMX has all the same functions and features, but 3 band capability!

Add Bands to your MMX!
If you purchased an MMX Morse Code Transceiver with less then its full complement of bands, you can always add a band board at a later time.
Each band board contains the specialized frequency-sensitive components and control circuitry for the band it was designed to operate on. The band board is automatically sensed and the band is automatically added to the available bands via the Frequency Button on the Main Screen. When you select the band for the card, it is automatically connected into the circuitry of the SDR receiver and the transmitter, and ready to use instantly.
Each band board also contains protection components to prevent overload of the final power amplifier (PA) of the transmitter in adverse circumstances. The protection circuit is automatically resettable in most circumstances. While it is very unlikely to cause interruption of the ability to transmit on its band due to a failure of the protection components, a backup band card is not a bad idea in cases where getting one repaired is difficult.
Currently available are 80 meter, 40 meter, and 20 meter band cards.
Mini-Keyboard for PreppComm Transceivers
The Mini Keyboard is a lightweight and compact keyboard for the MMX or DMX-40 Morse Code Transceiver, as well as future PreppComm Morse Code transceivers. It weighs a mere 0.7 lb, and uses very little power.
NOTE: You do NOT need to order a keyboard when ordering a DMX-40 or an MMX. One keyboard is included in your kit!
Backup Keyboard
Of course the keyboard will work with most computers as a keyboard, as well, such as when your keyboard batteries are dead, and you don't have time to recharge or you don't have any AAA or AA batteries handy.
DMX/MMX High Power Solar Battery System
USA SHIPPING ONLY!*
The High Power Solar Battery System
The High Power Solar Battery System includes the following items:
1. A compact, 4 panel 11 watt solar panel with >22% efficiency for full 5V 2A USB 2.0 charging power. This is a very nice, compact unit that feels like a small book when folded up. This is the most compact design for charging just one device at a time, or two devices at a slower rate.
2. Our Solar Battery, a 20 Amp-Hour battery with a great flashlight and a compass built in. This is a very powerful battery, only 29% less power than our Super Power Solar Battery System.
3. A 5V to 12V cable to power your MMX or DMX from the battery bank
4. A USB A female to C cable to connect the solar panel to the battery for charging at the maximum rate.
Our Super Power Solar Battery System provides additional features and more power.
About Amp-Hours
Batteries based on multi-cell Li-Ion batteries are normally rated at the voltage of a single cell, typically 3.6 volts. This is true of this battery, as well. However, there is a power conversion circuit to up the voltage to 5V for the USB outputs. Because of the higher voltage and the loss of energy in the conversion process, typical output at 5 volts is around 12 - 13 Amp-Hours, and at 12V, after being converted a second time, is about 4.8 - 5,0 Anp-Hours. Compare this to. typical Gel Cell 12V battery, rated at 7 Amp-Hours. Sounds like the Gel Cell - at 3x the weight - wins, right? WRONG, because you are not supposed to discharge the Gel Cell more than 50% of charge - that is, only 3.5 Amp-Hours! So this High Power battery, which has over 4.8 Amp-Hours of actual usable power, is significantly better, and ⅓ the weight and size.
In addition, all of the components can be packed into the included zipper canvas bag, shown in the image. Weight is less than 2 lbs!
Performance
The total package provides all you need to power your MMX or DMX off grid, either for a short period, or for an extended period. Your MMX or DMX will operate in receive mode for over 30 hours from a fully charged battery without recharging. A typical usage pattern allows you to operate continuously for 8 hours a day both transmit and receive on only 2 hours of sun per day. A complete battery recharge takes about 6-7 hours of sun.
IMPORTANT: The 5V to 12V cable that connects your MMX or DMX to the battery provides 12V with current limited. This prevents damage to your PA (power amplifier) when under stress from high SWR. This is a very valuable safety feature.
*Batteries cannot be shipped internationally. You can request a refund via PayPal after you receive your product for the cost of the batteries in that case.
The Right Speaker
for your MMX or DMX-40!
There are a lot of variables in the modern self-powered speaker products. Finding the right one that works for the application in mind - allowing you to hear the audio from the DMX-40 or MMX without using headphone.
It turns out that most of the critical functions are not published, so you find out the hard way that the speaker does not work for you. For example, I have a speaker that "forgets" it is plugged into the MMX after having been turned off and back on. So, I have to unplug the audio cable, and plug it back in every time. Nuts. Who would have thought even to ask?
And then there are the speakers that claim to have AUX capability, but when you get them in your hot little hands, hey, where is the AUX input jack? Oh, it's an auxiliary input from a USB source...??
So we took the time to find a suitable speaker to go with your MMX or DMX-40. It is not as small as I would have liked, but it works correctly. And, it has a lot of ofher features you may like:
1. Ability to be charged from our solar battery system
2. FM radio built-in
3. Bluetooth 5.3 connection to your phone
4. Built in microphone for clear phone calling
5. Play MP3 from a USB plug-in
6 Play MP3 from micro SD card plug-in (TF format)
7. Two 5W speakers with stereo sound, 45mm drivers
It also supports TWS, has auto shut-off, It talks to you. It makes coffee! No, forget that. So don't let your teenager get ahold of this! Keep it with your gear and it will remain in excellent condition, no sand in the works. Well, OK, it is also splash proof, whatever that means, so maybe no sand in the works.
The important thing is, plug it in and turn it on, and adjust the volume on the MMX or DMX-40. With typical radio signals and tone signals when transmitting, the speaker should last a day of operation. Charges in 4 hours via an included USB cable into a standard USB power source. Additional cables and USB power bricks available in our Accessories section.
It comes with a manual, but you will need your reading glasses.
The STX-2 Stand is a MAJOR upgrade from the original S2X stand, which did not work very well. While they both share a similar design, the new S2X-2 is much wider and has a better clip on that grabs and holds very nicely. The stand consists of two pieces that snap onto the bottom of the transceiver, so the top panel sits at a 45° angle to the surface, for perfect viewing and operating. The four rubber no-skid feet keep It steady on your desktop when you are pressing on-screen graphical buttons. Extremely lightweight, at about 0.02 Lb. Does not add shipping cost when added to any other product.
*Stand is not compatible with DitStorm Cypher*
Note: Photos are without rubber feet.
