it looks good, but it would be much better if you explain why you selected these values in each component. also it would be much better if you explain what would happen in each component when power is turned on so we know the scenario of input/output of each components. thank you very much for your explanation
argh this makes me remember first year of uni Reactance of Xc of the capacitor = 1/(jwC) How much power can you get out of a simple NPN transistor design?
Thank you for the Very good question. Basically you can measure with spice the current that goes through the NPN transistor, however this is not the exact power out. Since it depends a lot in your Antenna, you will need a 1/4 lamda antenna for best transmitting power out (lamda = c/f, which c is 3*10^8, and f is your frequnecy), I will do some tests to find maximum power out, but I expect 1mW to 100mW MAX. This is not RF power transistor, but general purpose that can work in this circuit

Were i can find more details to learn how to determinate what frequency i will get ?
What software you are use sir? Thank you
How this appk using is called?
LTSpice

Another way is to use SWR meter with an antenna, which measuring the real power out
please i will like to know a way I can measure the power of the transmitter
Thanks that's observe great nice video
You said 1K resistor and you wrote 10K resistor on R3. I am confused can you please explain.
Since for RF you have a capacitor, so if you will put 1K and 10K I don't expect much change, but to be on the safe side put 1K
thanks for the video's
you are welcome!
well
Long range??? Its an oscillator !!!! Few meters range!!!
SPEAK UP CAN BARELY HEAR YOU
Sir Hindi mai batayeye
