Less Weight
• The small 6-channel RX only weighs 7 grams and only draws 75 mA while most standard receivers weight around 42.5 grams.
• Compact design 39 x 39 x 9mm

Completely Immune to Environmental and Model Interference
Up to this time, conventional ground radios have been operating on either the 27 MHz or the 75MHz narrow band systems. These bands are

• On a single channel
• They are a very narrow band channels - only 20 KHz apart, and are extremely vulnerable to many causes of radio interference

These causes of interference come from some one else on the same channel - like

• Another modeler on the same frequency
• The FCC allows High Power 72 MHz users to transmit on channels that are in between our RC channels. Some local businesses have been know to transmit up to 50,000 KHz on these in between channels, giving off a lot of interference to RC and in some cases have even shut down the use of certain frequencies as some clubs due to know interference issues.

• Noisy sail winches motors
• Metal on metal, such as rudder post passing thru hull
• Metal Sidestays, mast, boom, boom vangs binding and twisting when maneuvering the sails

And the 3rd type of interference on the 27 and 75MGz band is 3im and 2im issues. This is when 2 or 3 other modelers are on frequencies that create a harmonic witch then creates interference on yet another channel.

However, Spread Spektrum has eliminated all these issues. The DX6 Spread Spektrum system is a DuaLink system that operates in the ultra high 2.4GHz band. This ultra high frequency offers several advantages over conventional 27 and 75MHz systems. First, all RF interference only exists below 300MHz. At 2.4GHz (that’s 2400MHz) the operational frequency range of the Spectrum system is 8 times higher than the range of this model-generated RF noise, making the system immune to these types of interference. Secondly, unlike the 27 and 75MHz band, the FCC limits the power output in this 2.4GHz to a maximum of 1watt. So, consequently no “high power” commercial users interspersed in the 2.4 GHz band.

Third, the FCC also Mandates a function called Collision Avoidance on the 2.4GHz band - meaning anything turned on in the 2.4 range must be cognitive or aware of other things in that band. So, when the DX6 is turned on, the first thing it does is scan all 80 channels looking for a open channel to choose. Once it finds one it then locks on and then turns on the transmitter. After it does that, because the DX6 is a DuaLink system, it then searches for a second open frequency, locks into that one and then transmits on this second frequency also. Thus, DuaLink means 2 transmitters and 2 receivers and it actually transmits and receives on 2 frequencies simultaneously. Collision Avoidance prevents a system from coming on a frequency already taken and prohibits other systems from coming on and interfering

• WIFI
• Wireless routers
• Cordless phones

Anything on the 2.4 GHz band must have "Collision Avoidance".

Spektrum's "GUID"
• Each DX6 has a chip that has it's own GUID, Globally Unique Identifier. This GUID or secret code has so many digits that it is possible to have over 4.2 Billion different combinations.

• The transmitter comes from the factory with its own unique GUID pre assigned. All receivers that want to communicate with this transmitter will first have to be taught the transmitter's GUID by a process called binding. Once a receiver is bound to a particular transmitter, that receiver will only take commands from that transmitter and nothing else.
• You can bind an unlimited number of receivers to a single transmitter
• And you can bind a receiver as many times as you want
• The DX6 is sold with the receiver already bound to the transmitter - so one really only needs to bind addition receivers

No Frequency Overlaps or Crystals
• Here's the best part... no more changing crystals... no worrying about someone else on your channel.
• Simply turn the DX6 on and it scans for 2 available frequencies, then set the TX and RX. You can arrive late and even with a race going on, turn on the system, and it will not interfere with those racing... but it will set itself and your ready to go.

Excellent Range
• There was some concern about the range since the antennas are only 6" long. I personally check the range and it is excellent 500+ yards.
• I tested the Spektrum vs Futaba systems. While both systems were hooked up and operating a servo, I began to walk away holding both RX's. I kept moving both sticks while my son on a walkie talkie would let me know if the servos were functioning ok. I was also holding a GPS to be able to judge the distance I was getting from the RX's.
• At 350 yard, the Futaba system started to go crazy and was soon after out of range. The Spektrum was still operating perfectly. I then continued to 500 yards, and I was amazed the Spektrum was still showing no signs of any problems. I stopped at 500 yards not because I was out of range, but because I could not imagine ever sailing further than that.... I could just barely see a waving arm at that distance. So no worried as far as range problems.

No more Interference
• The Spektrum's DX6 sport park flyer system utilizes patent-pending DuaLink ™ technology to create a secure, reliable, robust 2.4GHz spread spectrum link!
• Because the signal is pure digital, it means that glitches are a thing of the past too. No more annoying glitches that shatter the confidence and cause you to worry about crashing. They're a thing of the past too.
Not to mention the nasty intermodulation issues that have plagued 27, 72 and 75 MHz like 2IM, 3IM and adjacent frequency. They too, can't affect DSM.

Computer Radio
