Radio reception
The antenna signal is received and fed to the antenna amplifier. In order that the antenna signal should not interfere with the heating coil power supply, the amplifier contains a filter which blocks the antenna signal. The heating coil ground side contains an antenna filter which blocks the antenna signal from ground.
