    nice one vikas,
    i had it archived in my drive and forgot abt it.
    The only problem with me designing it is the inductor value design

    Default specs

    The guy said that it could support 9600 bps baudrate over 9 - 10 M with onboard batteries .. looks pretty good to me . just on ething do we get the transistor metined in india ??? or any good replace ment which is availible here

    Default Success?

    Any body succeeded in implementing this ?

    If yes, it'll be just great to get a walkthrough up on the site...

    Homemade RF ! WOW!

    Vikas;
    I am unable to find the Mpsh34 and Attiny 12 microcontroller.I have the data sheet for Mpsh34.It is a fairchild and amtel product.I searched in chennai.Both these are nowhere to be found.Any substitutes.Does anyone know of a pace in chennai where I can get them.I searched Ritchie street.The shopkeepers are very indifferent and baffled!!!!!!!Are fairchild products available in India.

    Default replacments

    Well you can replace the tiny with other series of AT90S2313 , 8515 etc
    but i can not tell you about the transistor

    Hey;
    Check this out got some equivalents for the transistors
    2N4401 = BC337a, BC637, BC639, 2N2221, 2N2222
    MPSH34 = BF199, BF224, BF311, BF373, BF497
    Is that ok.I want to cross check with you guys before implementing them in circuit.
