Description
Technical field
The present invention relates to radio field more particularly to a kind of radio Intellectualized monitoring methods.
Background technique
Radio adjustment frequency range is also referred to as adjusted covering or is called to scale.His purpose is to keep doubly-linked capacitor whole
Whole back-outs are screwed into, the received frequency range of institute is precisely entire medium wave (535~1600 kilo hertzs).He is by adjusting the machine
What the magnetic cap of oscillator coil L2 and the compensating electric capacity Cbt of oscillation circuit reached.
Radio with computer function receives the broadcast in a low side radio station, such as 640,000 when adjustment first
Conspicuous program.If the position of pointer is lower than 640 kilo hertzs, illustrate that the inductance of oscillator coil L2 is small, it can be oscillator coil
Magnetic cap precession it is some, until pointer is until 640 kilo hertzs of position receives 640 kilo hertzs of station broadcast;If pointer
Position is higher than 640 kilo hertzs, illustrates that the inductance of oscillator coil L2 is big, the magnetic cap of oscillator coil can be screwed out, Zhi Dao
Until 640 kilo hertzs of position receives 640 kilo hertzs of radio station.
Then, the broadcast in a high-end radio station, such as 1332 kilo hertzs of program are received then.If the position of pointer does not exist
It is necessary to adjust compensating electric capacity Cbt at 1332 kilo hertzs, until pointer just receives 1332 kilo hertzs of radio station 1332 kilo hertzs of position
Until program.Low side high in this way is adjusted repeatedly and can be harmonized two or three times.
