Hai all friends,
Does anybody know about a walkie talkie circuit diagram which uses 3 transistors (npn rf - can't remember the name:-() for boosting the signal, 3 nos 10.7 mhz ceramic filters and 1 capacitor and 1 resistor for oscillators receiver.
The transmitter uses a IC with Nand gates (quad nand -2 input) with 1 no. of 10.7mhz .
I used the circuit in my childhood ( 8 - 9 years back). I don't have the circuit with me. Can anybody help ?:?:
I remember the schematic very hardly. but i uploaded how it looks. http: / / obrazki.elektroda.pl /67_1283847861.jpg
I am 100% sure, both transmitter and receiver does not have any coils, and it worked.
