15W FM PLL Stereo audio 76-108 MHz frequency Digital LCD display Radio broadcast Station Receiver GP antenna

Descrtion:

Features: 15W FM 15 w FM stereo PLL FM launch module maximum 18 w FM audio frequency control up to 8 km This suite is bulk package, need buyers to welding (relatively difficult welding ch we have welding welding) without having to worry about, without any test. After welding can be used in acconce with the specifications set! Without any other debugging! While all of the materials for electronic information, buyers need to leave email after purchase we unified the hair! Or online to send! This kit includes all the components and circuit boards, but does not include the power supply, antenna, cable, audio cable and coaxial cable. A 15 w FM without any debugging. Need you're a novice or a veteran, as long as you will welding, you can 100% succeful DIY a high-quality FM Control panel components: mainly consists of 51 series microcontroller and a dot matrix LCD display screen and a keyboard. Launch plate parts: digital FM radio ch launch sc3355 + 9018 + 2 + 2 + RD15HV sc2053 level 4 high frequency power amplifier and power regulation components. suite key features: 1, DSP + PLL technology, make the frequency more stable, the frequency does not change with the environment and produce frequency drift. 2, no need any adjustment, bring the fun of DIY to beginners. 3, the frequency can be continuous adjustment within the specified . 4, with microphone input interface, and can through digital potentiometer to control the volume of the microphone. 5, audio input by digital potentiometer which can adjust the volume. 6, power can be between 0.1 W and 15 W maximum power continuous adjustment. 7, the power output network for harmonic suppreion is very good, make the output spectrum is more clean 8, set the frequency and volume of power lost protection, the next boot does not need to set up again! Suite main parameters: 1, the input voltage: dc 12 v About 2, input current 3.0 A 3, the audio signal: the maximum input Vpp is le than 1 v. 4, microphone types: cylinder microphone or microphones!!!! 5, the output power: 0.1 W - 15 W continuous adjustable! 6, the output impedance: 50 Ω 7, working frequency: 76 m - 108 MHZ Step: 8, frequency of 0.1 MHz 9, the distortion degree: 0.03% ~ 0.1% A, the board size: fire board: 117 x 70 mm (excluding fin) Control panel: 58 x 36 mm B, the launch distance: more than 8 km (premise is open field emiion) C, stereo separation degree: greater than 63 db The suite is demanded by beginners special design, basic no debugging, debugging difficulty is basic for 0. 100% as long as according to the correct welding operation can be succeful. Whether you are veteran or a rookie, all can enjoy to spend the least cost FM launch DIY fun! As for patch welding, we don't have to worry about too much, this suite USES capacitive strs are 0805 encapsulation, welding board and plug-ins is the same, Antenna must be used in this 50 ohms, frequency of about 100 m antenna, shall not be used conductor, rod antenna, 2.4 G , radio instead GP antenna 65-375MHZ

The appearance of the antenna is as shown. It is a more efficient FM antenna. It can also be placed outdoors. It can also be hung in the air. Each of the s can be pulled according to the transmiion frequency. It is more ible than the GP antenna of the currently available fixed-length , making it more effective to resonate with the transceiving frequency. Achieve higher transceiving efficiency. The length of the four s is 20 cm to 1.1 m. It is suitable for wider frequency adjustment. The working frequency can be adjusted from 65 MHz to 375 MHz. For different transmiion and reception frequencies, the length of each is (300/frequency) / 4 (meters), and the middle one is pulled up. The three surrounding ones are pulled downward by 45 degrees. For example, the transmiion and reception frequency is 107.3MHZ. Then each has to pull: (300/107.3) / 4 = 0.699 meters, When you feel that the transmiion distance of your FM or the sensitivity of the FM receiver is not satisfactory, connecting this antenna can have an immediate effect.
