rf oscilaotrs


Recommended Posts

Your other post has replies with circuits that detect the RF oscillator in your cell phone (mobile phone) when it transmits a signal that it is on and is operational just before it rings an incoming call.

You don't need to make two posts about the same topic.
You don't need to make an RF oscillator.

what shld i do then???

Did you make the circuit which I attached in your other post? You said you made something that didn't work. Was it that circuit that didn't work?
Then list the part numbers of the parts you used and the battery's voltage. Maybe you used an ordinary 555 IC instead of a Cmos 555 IC so it will work with only 1.5V. An ordinary 555 IC needs a minimum supply of 4.5V.
