Hi All,
Planning to build my own short distance transmitter for car and home any ideas where I should start from. I'm familiar with circuit theory - may need to refresh few things, but that's the point of this project.
Also like to simulate my circuit in Pspice, if Im lucky, I would get some kind of ac/dc repsonse before buying any component that I may not use.
Transmitter initial specs:
9v battery or less (1.5v is ideal) -- low power consumption as its meant to be for a very short distance
Variable frequency (may need POT)
FM: 86-108MHz will be used..
Please help and point me in the right direction as there are many circuits already available on the internet. Selection is overwhelming. PLL or no PLL.. just a tank or oscillator?
Regards,
Raveel
