    hello all, im building this:

    Ive gotten a bit ahead of myself, as ive aready designed board layout, printed and etched traces.. and now as im waiting for flux pen to arrive tomorrow, im wondering if i made a mistake..

    Ive substituted the rca connections for a 3.5mm audio jack. Is this ok?

    I guess what im asking is, would there be any resistor value difference coming off the input. rca resistor value(22k as shown) vs 3.5mm resistor value..

    All parts have already arrived, so im hoping the 10k pot will still fit the bill.

    Thanks!

    i was hoping there was no issues, as i have done the same in the past.. but im worried the receiver was built for this scenario vs the simple circuit im building

    The RCA jacks are just more universal inputs. What are you broadcasting?

    Let us know how it works out!

    This schematic i found, is to make a stable fm transmitter for the car. Signal powered by phone via 3.5mm jack
