DSMX vs DSM2: Choose the Best Protocol!

If you’re into RC’s, you must be confused between dsmx and dsm2 like everyone else. But that’s a common scenario among all RC fans. 

But don’t worry, we’ve got your back. We’re here to help you decide which is better.

So,  dsmx vs dsm2, which one’s better?

Dsmx and dsm2 are both made by the same company. They even have the same Wideband DSSS foundation. They both use 2.4 GHz technology. But, dsmx uses an advanced version of the FHSS algorithm. This lets the frequency of dsmx bounce between 23 channels every time a packet is transmitted. This makes its signal network more protected. And therefore, dsmx is better.

This is just some surface-level information. You shouldn’t decide from just that. Interested in knowing the detailed information? Read on!

This might not be enough to decide which is better. We understand that. So we’ve curated a detailed comparison for your convenience.

DSMX Vs DSM2: Detailed Differences 

When Spektrum launched its 2.4 GHz RC technology, the RC users were taken by a storm. This 2.4 GHz transmitter and receiver technology was a revolution in the world of RC. 

Both dsmx and dsm2 use 2.4 GHz technology. They’re both made by Spektrum. They even have the same Wideband DSSS foundation.

So where’s the difference you ask?

There’s only one primary difference. That is the process through which these transmitters hop from one channel to the other. The dsm2 transmitter randomly chooses two channels and gets the work done. 

Also, the dsm2 also has a special transmitter for drones. They call it DuaLink, which provides a superior RF linking between the user and the model. You’d know this if you know how drone transmitters work.

They have more similarities than they have dissimilarities. Let’s look at them now-

Wideband DSSS Foundation

The foundation of both dsmx and ds2 is built under the wideband DSSS. Unlike the wideband signal, the narrowband 2.4 GHz used by other transmitters is prone to problems. 

The dsmx is one of the pioneering products launched by Spektrum. It is the world’s one of the first Wideband, Frequency Agile 2.4 GHz signal protocols. It also has one of the most advanced spread spectrums for RC technology.

And the Wideband is under the DSSS foundation applied on all of Spektrum’s technologies. To enjoy these features to the fullest, try using them with flysky or frsky.

The possibility of suffering from major packet loss or data loss is high. Especially at times of on-channel interference. 

The coding gain of wideband is one of the reasons why it’s so strong. This basically means the frequency of these signals is stronger than your average 2.4 GHz.

Let’s state a fact, wideband signals can reach 3 times the power of narrowband signals. Not to mention, they can do that with the same amount of power.

If you want a good analogy, think of narrowband as a stream and wideband as a river. You need a lot more interference to stop a river than when stopping a stream. You should try using the dsmx with Spektrum’s dx6 or dx6e to get the best result.

The FHSS Algorithm 

You already know that both dsmx and dsm2 use wideband DSSS. But, dsmx use a more improved version. The interference of dsmx is better protected and the frequency agility’s reconnection time is faster.

But, the dsmx doesn’t only hop from channel to channel, it has an agile wideband signal. It uses a very advanced version of the FHSS algorithm to coordinate the frequency shifts. FHSS transmitters usually hop on 23 different channels in the same pattern.

But, dsmx transmitters use Globally Unique Identifier (GUID) to own a unique pattern in shifting frequency. And they use these unique patterns all throughout the 23 channels in 2.4 GHz.

This unique shift in the frequency is what provides your dsmx interference with extra protection. Also, this is what provides you with a faster reconnection time.

With these transmitters, you’ll be able to fly both 3-blade and 2-blade prop quadcopters efficiently and accurately. 

The Range of The Spectrum’s Spread

Dsmx and dsm2 use three-dimensional signal protection called MultiLink. The MultiLink feature offers a dual path redundancy. 

The combination of MultiLink and dsmx’s advanced FHSS algorithm makes the signal of dsmx very strong. 

The Winner

The winner is dsmx. Even though they have a very small number of differences, these are quite acute.

As dsm2 uses only 2 channels, other people can also be using the same channel. But, dsmx uses 23 different channels and the chances of people using the same channel are low. 

Thus, increasing the reception time of dsmx users. Also, the dsmx network is faster and far better protected.

And therefore, our winner is dsmx.


Question: Are the equipment of dsmx and dsm2 compatible with each other?

Answer: Yes, they are. You can use dsm2 transmitters with receivers of dsmx. Also, you can use dsmx transmitters with dsm2 receivers. Since they both use wideband DSSS foundation, no combination between the two will hamper the experience.

Question: Does dsmx come with Servosync and Modelmatch Technology?

Answer: Yes, they do. They also come with all the features that are already available in dsm2.

Question: Can dsm2 transmitters use an add-on from dsmx?

Answer: Yes, they can. But dsm2 users don’t usually feel the need to. After all, you’ll only need a dsmx add-on if you’re going somewhere crowded with 2.4GHz signals.


This is all there’s to know about dsmx vs dsm2. Dsmx is better than dsm2. After all, it was developed sometime after dsm2.
