Commonly used intermediate frequencies110 kHz was used in Long wavebroadcast receivers. [1]Analoguetelevision receivers using system M: 41.25 MHz (audio) and 45.75 MHz (video). Note, the channel is flipped over in the conversion process in anintercarriersystem, so the audio IF frequency is lower than the video IF frequency. Also, there is no audio local oscillator, the injected video carrier serves that purpose.Analoguetelevision receivers using system B and similar systems: 33.4 MHz. for aural and 38.9 MHz. for visual signal. (The discussion about the frequency conversion is the same as in system M)FM radioreceivers: 262 kHz, 455 kHz, 1.6 MHz, 5.5 MHz, 10.7 MHz, 10.8 MHz, 11.2 MHz, 11.7 MHz, 11.8 MHz, 21.4 MHz, 75 MHz and 98 MHz. In double-conversion superheterodyne receivers, a first intermediate frequency of 10.7 MHz is often used, followed by a second intermediate frequency of 470 kHz. There are triple conversion designs used in police scanner receivers, high-end communications receivers, and many point-to-point microwave systems.AM radioreceivers: 450 kHz, 455 kHz, 460 kHz, 465 kHz, 470 kHz, 475 kHz, 480 kHzSatellite uplink-downlinkequipment: 70 MHz, 950-1450 Downlink first IFTerrestrial microwaveequipment: 250 MHz, 70 MHz or 75 MHzRadar: 30 MHzRF Test Equipment: 310.7 MHz, 160 MHz, 21.4 MHz

The industrial, scientific and medical (ISM) radio bands were originally reserved internationally for the use of RF electromagnetic fields for industrial, scientific and medical purposes other than communications. In general, communications equipment must accept any interference generated by ISM equipment. The ISM bands are defined by the ITU-R. {| ! Frequency range [Hz] ! Center frequency [Hz] !
