The AN / USC-55 commander's tactical terminal ( CTT ) is a multiservice-developed, special application, UHF satellite communications receiver that can be dedicated to receive critical, timesensitive intelligence by commanders and intelligence centers at all echelons, in near-real-time, at GENSER or SCI levels.

Communications receivers may have more complex AVC systems, including extra amplification stages, separate AGC detector diodes, different time constants for broadcast and shortwave bands, and application of different levels of AGC voltage to different stages of the receiver to prevent distortion and cross-modulation.

But if you would be dissapointed if you can't receive amateur stations very well you should consider spending just a few hundred dollars more to buy a good second hand communications receiver . talk ) 17 : 38, 14 May 2008 ( UTC)

Their use is limited to low signal amplitudes to avoid obvious distortions as the capacitance would be affected by the change of signal voltage, precluding their use in the input stages of high-quality RF communications receivers, where they would add unacceptable levels of intermodulation.
45.
They are used in systems such as radio broadcasting, broadcast television, two-way radio, communications receivers, radar, cell phones, and satellite communications, as well as other devices such as garage door openers, wireless microphones, Bluetooth-enabled devices, wireless computer networks, baby monitors, and RFID tags on merchandise.

The difference between the two is that broadcast receivers only receive broadcast bands, such as the medium wave and / or longwave AM broadcast bands and the VHF FM broadcast band, while a communication receiver receives a wider part of the radio spectrum not used for broadcasting, that includes amateur, military, aircraft, marine, and other bands.
