This is the schematic for an FM transmitter with 3 to 3.5 W
output power that can be used between 90 and 110 MHz. Although the stability isn't so bad, a PLL can be used on this circuit.
This is a circuit that I've build a few years ago for a friend, who used it in combination with the BLY88 amplifier to obtain 20 W output power. From the notes that I made at the original schematic, it worked fine with a SWR of 1 : 1.05 (quite normal at my place with my antenna). |

| it helps me to the final project .so that i want schematic diagram and discription of each components and ratings. | ||
| U1 7810 = LM 7810 or equivalent voltage regulator, out=10V | ||
| I think you can change the frequency of transmission by adjusting C14. Regards | ||
| The circuit seems very useful.But it will be very helpful if you clarify my following things 1. What is its working range or how to set the frequency range. 2.Will it depend on the antenna height. 3.What is the use of 7810 Regulator. | ||
| 1.WILL YOU TELL ME ABOUT "U1 7810 REGUTATOR". USE AND OPERATION 2.WHAT WILL BE THE RANGE ? 3.HOW TO SET THE FREQUENCY? THANK YOU | ||
| i want to know the range of this transmitter. | ||
| it will be allowed are not for project and how long distance it will work? | ||
| i want to build a 100 watts or greater transmitter, what i'm trying to do is to learn how to build a land mobile radio, mostly like the ones made by Midland or Vertex, is there anyone that can direct me to any informations. thank you | ||
| I wish to build 3 Watt FM Transmitter as my project, please guide me on the schematic diagram and send more detail in respect of the circuit diagram through my email omarhassan2323@yahoo.com | ||
| can you send to me FM Transmitter schematic and proposal to me as fast as possible.thx..... | ||
