    A07B500S manual Ground loops Sometimes connecting various ground sockets having different potentials may produce some unwanted loops, which may create hum in the modulation: in this case it is essential to firstly identify the origin of these currents, which normally spring from the antenna ground, mains supply ground or from the input low frequency signals ground.

  • Page 24 A07B500S manual All the rules concerning the radio transmitters in FM band include some limits of accuracy and stability of the output frequency. These limits usually depend on parameters of internal crystal reference, which are at the same time connected firstly to the temperature and ageing of the crystal itself.
  • Page 25 A07B500S manual On the opposite, if an external stereophonic source is already available, the LEFT and RIGHT inputs must be kept free by using the MPX input (rear BNC); in this case the transmitter must be set to MONO even if the transmission is STEREOPHONIC.

    A07B500S manual MODULATION MEASUREMENT General information The broadcast reception at frequency modulation is often made difficult because of the networks exceeding crowding; the interferences due to the adjacent channels makes the listening unpleasant.

The process is described in the IEC 244-13 standard and consists of modulating the transmitter with noise as above, with a deviation equal to 32KHz. This work condition corresponds to the maximum allowed band occupation and to a radio broadcast spreading dance-music which modulates ±75KHz.
