Know your event objective. If the aim of the event is to educate people then the entertainment is not the key element of the event. You would do better to use some light form of entertainment during the break to help attendees unwind and rel Music is a vast sea and there are lots of singers in the world who earn so much fame because of their singing, voice and style and Rob Thomas is one of them. He is one of the best singers whose songs become very popular and he has great fan

These types of communications are governed by the rules of each country,so what should not exceed certain limits, the omission of such limits ispunishable by fines and penalties.The miniature FM transmitter has been designed in sucha way that does not exceed such limits on their frequency of oscillation whichis comprised between 88 and 130MHz and the field generated by the irradiation,does not exceed 50 mV per meter at a distance 15cm of the circuit.If you join the rc cars circuit following thespecifications below you will not exceed these limits, since any changes madeto the pro circuit including such a variation in supply voltage, change thescope of the signal. Finally you need to solder the microphone, taking intoaccount their polarity, the antenna and connector for 9V battery respectivesprats and secure the battery holder using the screws.OperationThe transistor Q2 is the oscillator, Q1 is theamplifier to modulate the signal. The modulating signal is applied to the baseof Q2 via C2, R6. The capacitors C6 and C7 are part of the oscillator. Q2, L1,C5 form a voltage-controlled oscillator circuit, which is modulated by theaudio voltage, is amplified by Q1. C5 is used to tune the oscillator circuit bysetting the frequency of oscillation. C8 acts as a filter capacitor.Once you are sure that all rc cars components have beenassembled properly, you can proceed with the testing and calibration of the radiocar model circuit. To do this, place a FM radio near the circuit, find a pointon the dial in silence (no radio) and receiver volume up to a point where youcan hear the interference. Connect a 9V battery to the circuit and listen to theradio. Slowly and with the help of a small screwdriver, adjust the condenser(trimmer C5) until the receiver is heard a whistle or sound similar, whichmeans that at this point has been tuned to the transmitter frequency dial. Youcan then speak into the microphone and be heard on the radio the talk.If the selected frequency is not achieved goodreception, repeat this procedure at another point on the FM band. Alternatively,instead of varying the capacitor, tune the radio to find the point where youfeel better reception (silence). If after doing this, tune the rc cars transmitterfails, you can adjust the coil that forms the oscillator circuit pooling theirturns to raise the frequency, or separating them if you want to reduce it abit.
