Windows RDS control software System

The software can run in demo mode without the RDS encoder connected.

Magic RDS 3 - default Windows control software
Download the Software here:

Note: The RDS encoder contains two types of memory. These are marked as RAM and EEPROM. Like any other computing system the RAM holds all operational data which are also used for transmission whilst the EEPROM is used for the data storage during power-off. By default the button Send will fill the RAM only. The button Store will fill the RAM and also stores the data into EEPROM. The Store button behavior can be changed in Options - Preferences - Buttons.

If the user forgets to store the data into EEPROM, the settings will be lost when the power is disconnected.


FM Transmitter Connection

Basic rules:
The RDS signal must be fed into modulation signal (added to MPX signal if stereo encoder is used).
If stereo encoder is used, one of its outputs (MPX or pilot tone) must be fed into the RDS encoder input to meet the synchronization requirement.
Following figures show various situations and corresponding methods of connection:

Separate stereo encoder - default connection.

Stereo encoder with only one MPX output provided.

FM transmitter with only one MPX input provided.

Both stereo encoder and FM transmitter with only one MPX connector provided - loopthrough mode. It is recommended not to use this mode if any of the other connections are possible.





FM transmitter with integrated stereo encoder.


FM transmitter with integrated stereo encoder, Only have a AUX in / RDS in / SCA in .
In case of mono transmission (no stereo encoder used) the RDS encoder input may be left unconnected (since there is no need of external synchronization) or it may be used for the audio signal injection in the case that the FM transmitter has only one input connector.

How far(long) the transmitter cover?

The transmission range depends on many factors. The true distance is based on the antenna installing height , antenna gain, using environment like building and other obstructions , sensitivity of the receiver, antenna of the receiver . Installing antenna more high and using in the countryside , the distance will much more far.

EXAMPLE 5W FM Transmitter use in the city and hometown:

I have a USA customer use 5W fm transmitter with GP antenna in his hometown ,and he test it with a car, it cover 10km(6.21mile).

I test the 5W fm transmitter with GP antenna in my hometown ,it cover about 2km(1.24mile).

I test the 5W fm transmitter with GP antenna in Guangzhou city ,it cover about only 300meter(984ft).

Below are the approximate range of different power FM Transmitters. ( The range is diameter )

0.1W ~ 5W FM Transmitter :100M ~1KM

5W ~15W FM Ttransmitter : 1KM ~ 3KM

15W ~ 80W FM Transmitter : 3KM ~10KM

80W ~500W FM Transmitter : 10KM ~30KM

500W ~1000W FM Transmitter : 30KM ~ 50KM

1KW ~ 2KW FM Transmitter : 50KM ~100KM

2KW ~5KW FM Transmitter : 100KM ~150KM

5KW ~10KW FM Transmitter : 150KM ~200KM
