Several announcements about the transmitter:

1. Transmitting distance:

The transmitting distance is mainly determined by the height of transmitting antenna, antenna gain, transmitter power, actual transmitting environment and the sensitivity of receiver. If the distance is not too far in using the transmitter, one can significantly increase the transmitting distance by enhance the height of transmitting antenna.

2. Regarding the audio input:

the volume input should not be too large, and saturation

distortion is likely to occur in the assembly. So when the audio distortion occurs, try to lower the volume input.

3,The percentage of output power is a non-linear relationship.

Therefore, the power percentage is only for the convenience of the user to adjust different power. The actual power is subject to the output test. The same voltage standing wave ratio is only a rough reference value and is not very accurate.

4,The transmitter antenna output must be connected to a standard 50 ohm transmitter-specific antennawith a center frequency that must match the transmit frequency.

The antenna must be 10 meters away from the transmitter.

Never use other non-professional antennas. Otherwise, the transmitter will not be responsible for burning it! Or it can be tested with a dummy load of not less than 100W 50 ohms.

The transmitter is protected against standing wave protection. The standing wave protection display display icon is shown in the figure below.

Appear on the map “Please Check ANT” flashes simultaneously.

He says that the antenna VSWR is too large, is protected.

Immediately remove power to check whether the antenna is connected and match.

10	106 MHz	13.8V	7.7A	57W
11	108 MHz	13.8V	7.8A	54W

Note: The above test data is for reference only. The actual test power of each device is different due to the test temperature and the parameters such as test cable and power meter. Therefore, the actual test data will be biased.
