What air data rate you choose will depend on the following factors: If you choose an unsupportedĪir rate then the next highest rate from the supported list will be Potentially add it to the register tables. If yourĪpplication needs a different air rate for some reason then we can The lower you set theĪIR_SPEED the longer your range, although lowering the AIR_SPEEDĪlso lowers how much data you can send over the link. Of over a kilometre with small omni antennas. The default is 64 (which is 64kbps) will give you a range The key parameter that controls the range of your radios is theĪIR_SPEED. You may need to build a stand to hold it to Ground station antenna should be well clear of obstructions and a couple So if you have 18dB of fade margin, then you will beĪble to do roughly 8x whatever range you were at when you measured theĪnother key source of range problems is the antenna placement. Tells you your “fade margin” in decibels.

Is to subtract the ‘rssi’ and ‘noise’ numbers, then divide by 2. To determine what your range would be, a rough rule of thumb If the ‘rssi’ and ‘noise’ levels meet on the graph then you will lose If you get this, then you could try using a different Perhaps the most common source of noise with the 3DR-433 is noise from

Range I would need to move the radio further from the motor and ESC. That shows I’m getting some noise from my motor. Levels on the plane were lower, then they went up after I started the That at the start of the flight (before I started the motor) the noise In the plane are higher than the noise levels on the ground. SkyFun with a pair of 3DR 433 radios) you can see that the noise levels

the amount of noise being received in the aircraftįor the best possible range you want the two noise lines to be low, and.

the amount of noise being received on the ground.

the amount of signal being received in the aircraft.

the amount of signal being received on the ground.

Wait for the log to load, then choose the When the window pops up choose Graph Log and select a log from a To work out what sort of noise you have, open up mission planner andĬhoose the “telemetry logs” tab.

Noise from other people operating radios nearby that are on the same.

Noise from your ground station computer, especially its USB bus.

Noise from the electronics in your aircraft (such as your motor, ESC,.

There are three key types of noise that are likely to affect your Telemetry logging built in to help you diagnose the source of the noise. That interferes with the operation of your radio. Radio emissions in the same frequency range that your radio is using The most common source of range problems is noise. Then what you need to do is graph the noise and signal levels from a If you get less range than you would expect from the above information
