Overview

MMX ZERO...

The MMX ZERO is loved by many current users. However, time moves on. The ZERO was specifically "just" a Morse code encoder/decoder, with no transceiver inside. Thus, no bands, and the name ZERO.

MMX ZERO was one of our best sellers for quite some time. But again, times change.

We introduced the DitStomr Cypher™ at HamCation in February, 2026. It was our most exciting new product introduction, and we ended up selling out our first production run in 2 days. We more than doubled the production run, and followed it by another of the same size. We started shipping in early April, with Release 1 of software. This was replaced with Release 2 in early May, and will again be replaced with Release 3 in late June. Each release increased the power of the decoder and added planned features as well as customer requested features.

The Cypher is the best alternative to the MMX ZERO, and is less expensive, and much smaller.

However, there are still some situations where you might want to consider a different alternative, the DMX-40. Yes, it does have a 40M QRM transceiver inside, along with the same guts as the MMX ZERO. Turned on, it operates like an MMX ZERO, until you turn on the internal transceiver. So if you want that package, with a built-in LCD rather than using an external divice to host the Cypher GUI (a PC, a tablet, a phone), then the DMX-40 is for you. Only slightly more expensive than the MMX ZERO.

Summary: ZERO discontinued, replaced by:

  1. DitStomr Cypher™, with full color graphical user interface (GUI) hosted on a browser on your device, with extraordinary decoding, audio scope, powerful band pass filter (BPF), and much more.
  2. DMX-40, with built-in LCD, good decoding/encoding, self-contained.

MMX Zero and IC-705

Great build and will also work well according to the recenties, but I can't get it to work with the Icom IC-705. Copied the method of operation with the IC-7300 but it does not work. Someone told me the function 'BK IN' must be 'ON' in the transceiver but I can't find that anywhere in the description of the Icom and the MMX Zero (IC7300). So the zero is on the side unfortunately.

Dick, I am sorry you are having problems making it work with the Icom 705. Unfortunately, I don't have one, and thus, can't give you instructions. However, I do know that customers do use the ZERO with the 705. Break In is simplly the method where the transmitter automatically turns on when you press on the key. The other setting is getting the offset to 1300 Hz, with a combination of the tone setting and the receiver offset. The sum of these two must be 1300. So, if your tone setting is 600 Hz, then you need to set RIT or receiver offset to 700 Hz, to the total is 1300. Then, you are golden. Let me know if you have problems with these settings. Help can also be found on the PreppComm Community, at preppcomm.mn.co.

it works ok for rx but i cant get it to tx on my yaesu 710

MIke, I hope our conversation on getting the settings correct for your Yaesu work out. It has to be in CW mode, and it has to be set to single channel paddle aka straight key for input. I could hear the tone in the bacfkground over the phone - the MMX is sending out just fine.

Eric is awesome ; product is awesome ; There were some small learning curves , me being a nwbe , i just need to learn the abr in cw and adjst ing the nobs . FYI Yaesu RIT is CLAR

Thanks, Mike. Mike IS a verified buyer, but due to our POS terminal not working correctly, the system did not recognize him. Note that it is difficult for us to convert our settings based on the IC-7300 to other products - a Yaesu transceiver in this case. We now know Yaesu uses Clarify rather than RIT (Receiver Incremental Tuning) as the terminology for ofsetting the receiver frequency.
