Re: rf circuit!
Thanks , i will try it out!
Added after 1 hours 30 minutes:
Don`t mind if i ask this ...
this badly drawn schematic, i followed a 27mhz toy car transmitter circuit board to drawn out...
the circle thing is bottom right was a tesla coil with 5 pin connection.
can help me identify the tx circuit and how it actually work ?
i tried tracing out the circuit and found pin 8 and 10 of the ic linked to the circuit .
The ic was SM6136, pin9 was Vdd and pin3 was Gnd... pin 8 was where the unmodulated data came out but pin 10 was "PC" which i doesn understand what it was for even in the datasheet as it was in chinese version as made in china.
can i replace the tesla coil with oscillator, how to do that?
possible to make just the transmitter out of this circuit with a line to feed in data for transmitting ???

i came across this schematic
the transmitter part looks the same as the one i traced out above... but the connection of the transistor were kind of differents ...
can anyone help me to understand ?
