FM TX + VCO

Post by ericyeoh »

Hi all,

I'm new to FM and i'm currently doing FM project. The project required to use "ISA" band which is 40.6xMhz for the TX. Besides, it also required to include with VCO in the TX design.
DO you guys have any info regarding to my design?

I got this circuit in web and the picture is bad, however i cann't even obtain the value.

If you are designing this you shouldn't be asking this kind of questions, it looks like you are way over your head in this.

ARRL handbook is a good start to get educated on these things.
