    hey docel....there is no such thing on bangalore robotics...only stuff abt voice recorder...... all searches on d net giv stuff abt how to buy ready made transmitter.... & d others have ready made modules...

    hey vikas load the circuit if u hav one.....i need radio frequency remote control (transmitter & receiver) to drive a 6-12 V motor..... without modules only transistors & ics n stuff...... paste d working of d circuit if u can...don't worry abt d electronics part...i hav to learn some time......

    You'll have to register!
    The power is just right for short erange communication. ( WONT specify range..)
    It is an FM Tx. use it eith any FM Radio.
    The range is min. 25Mtrs. (DONT KNOW the actual range of rentals!!

    Hi You wont get it ready.
    The circuit has the details : 12Turns, 26 gauge copper wire, 4mm dia.
    You can even try Telephone cable/hookup wire but single strand. It will still work.
    Dont change any component values, except transistor to BF494. Watch the Pin details!
    It will be good if you can avoid SMS language???
    Thank you!
