rf pll 27mhz transmitter
Hi there, I'm currently working on a project on RF tx and rx circuits. Currently building the transmitter circuit with frequency of 27MHz. We obtained the waveform and its oscillating, but the amplitude is low somehow(6V) when we're using 9V battery as our source.
This transmitting circuit aint working because the signal is not able to transmit out, unless the antenna of the transmitter touches the antenna of the receiver(remote control car).
We are not using any crystals for out tx circuit.
Any idea whats the cause of this incapability of transmitting the signal out?
Does the type of antenna plays a big role on the circuit?
