I beleive that my neighbor is using a jammer to block my vehicle remotes to remote start my car. Is there a circuit with a signal meter or led's that i can sweep the area around my house to see if the signal is coming from his house? RF Radio Circuits – Page 3 – Circuit Wiring Diagrams by the filter circuit made of L1, C3, C2. The L2 C4 circuit is set to the fourth harmonic or 144 MHz. The signal goes to the dual gate FET driver stage before finally radiating through the transmitting antenna. The output power is from 10…40mW. The radiated signal is also modulated by the gate circuit made of U1, U2, U3, U4.
