We decided to build a radio transmitter for our boarding school's hostel, its need about 100m radius indoor area to be covered.
I build this circuit on breadboard
**broken link removed**
but it is not working, by the way I changed the inductor to a 3.3uH and the capacitors to 1.8pF, which should oscillate at 92.3MHz.
I tried to test the circuit with my oscilloscope but it is caped at 20MHz so I can't test it.
Any one of you know what is wrong or know a good simple design of a PLL or even better coil less transmitter.
