The Crosley Corporation of Cincinnati, Ohio manufactured the Signal Corps Set, Complete, Radio, 284 (SCR-284) that consists of the Basic Component 654 (BC-654) and associated support equipment. [ 4 ] The SCR-284 was introduced in Africa during Operation Torch and was the first radio set used for communications from the beach to the U.S. Fleet ...
Enigma is one of the Graphical user interfaces developed for digital satellite receivers DBox-2 during the TuxBox project [1] in 2000-2001. The development was then continued by Dream Multimedia for their receivers. In 2006 Dream Multimedia released a new open source version of the software called enigma2. Around that time many receiver ...
Those that include VHF or UHF can be termed wideband receivers, whereas those without HF would be termed scanners, or surveillance receivers. Receivers without controls, that are operated or implemented in computers are in the list of software-defined radios .
The receivers were tuned at the pilot's control box by electrical cables and long mechanical tuning shafts, allowing remote control of power, mode, frequency, and volume. AN/ARC-5 set composition and control differed markedly from the earlier systems. Three-unit receiver racks were still predominant, but the receiver line-up was quite different.
PrimeStar was an American direct broadcast satellite broadcasting company formed in November 1990 by seven cable television companies including Comcast Corp. and TCI Communications Corp.

Modern decoders are typically compliant with the MPEG-4/DVB-S2 standard and formerly the MPEG-2/DVB-S standard, while older FTA receivers relied on analog satellite transmissions which have declined rapidly in recent years.
A receiver circuit that used larger amounts of regeneration in a more complicated way to achieve even higher amplification, the superregenerative receiver, was also invented by Armstrong in 1922. [ 11 ] [ 5 ] : p.190 It was never widely used in general commercial receivers, but due to its small parts count it was used in specialized applications.
