Description
87.5M - 108MHz 50W Maximum Up To 70W Stereo RF FM Transmitter Amplifier with Fan Radio Station Module DC 12V 13.8V 10A H4-002
Note: Long-term emission requires increased heat dissipation.
Parameters
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 antenna with 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.
