WebbYour station may receive signals from your vehicle’s noisy emitters such as ignition sparks, motors, or other electric devices. Your own transmissions, emitted very nearby from your mobile antenna, can also create RFI issues. Electrical ground loops and “common mode” currents can impose noise on your signals, both received and transmitted.
