RADIO TYPE CONVERSION RECEIVER

摘要

PURPOSE:To use a medium wave band amplitude modulated receiver as a guide receiver by converting a received FM signal into an AM signal and transmitting it to the medium wave band AM receiver through an electromagnetic coupling. CONSTITUTION:If the AM receiver 7 is stored in the AM receiver storage part of a radio type conversion receiver 1, a coil L2 in an antenna circuit consisting of the coil L2 and a capacitor C2 in the AM receiver 7 is brought into contact with a coil L1 in a high frequency output circuit 6, whereby an AM signal F0 turns into a voice signal through a detection amplitude circuit 7a and an earphone 7b in the AM receiver 7. On the other hand, a guide FM signal F1 through a guide transmitter 2 is converted into the voice signal Fa in an FM receiving part 3 of the radio type conversion receiver 1 consisting of an RF module 3a and a detector 3b, and is transmitted to an AM modulator 4. The AM modulator 4 amplitude-modulates the voice signal Fa and transmits the AM signal F0 to a high frequency output circuit 6.
