50W 87.5M－108MHz Maximum up to 70W Stereo RF FM transmitter
In order to protect his design, the engineer has erased the transistor model. Please feel free to contact us if you have any questions during use. Please leave your email when placing your order. We will send you a detailed instruction manual. Thank you
Note: Long-term emission requires increased heat dissipation.

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 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.
