Within a few years, Collins had introduced additional S/Line components, including the 30S-1 kilowatt power amplifier, the 30L-1 desktop power amplifier, and the 62S-1 transverter, which provided coverage of the 6-m (50 MHz) and 2-m (144 MHz) amateur bands. The KWM-2 transceiver replaced the KWM-1 using many of the S/Line's design features and ...
The Collins 75A-4 amateur radio receiver. The 74A4 and KWS-1 is an amateur radio receiver and transmitter pair made by the Collins Radio Company of Cedar Rapids, Iowa that were introduced in 1955. They were designed to operate using the then new single-sideband (SSB) voice modulation as well as CW and AM modes. They were influential in ...
The R-390A is a general coverage radio receiver capable of receiving amplitude modulated, code, and frequency shift keying signals. Its tuning range is from 500 kHz to 32 MHz, in thirty-two 1 MHz bands.
The last Signal/One radio was a re-engineered ICOM IC-781. Information available indicates there were 1152 Signal Ones built: 850 CX7, 112 CX11, 168 MS1030 (number of "C" versions is not known), 6 MilSpec1030C, 15 MilSpec1030CI Icom IC-781 conversions and 1 Milspec1030E DSP Icom IC-756 Pro conversion.

John Francis Rider (1900–1985) was an American radio engineer best known as publisher and author of over 125 books for radio and television servicing. He founded John F. Rider Publisher Inc. and was responsible for annual volumes of the Perpetual Troubleshooter's Manual from 1931 to 1954.
[1] Modifications requested by the Signal Corps were performed by Hallicrafters' engineers working with U.S. Army technicians at Fort Monmouth . They made a new version of the HT-4, which was known as the BC-610 transmitter, a part of the SCR-299 mobile communications unit, and production began in 1942.
A number of aircraft have been produced with relatively sophisticated integrated standby systems which may include additional functions. For example, the Rockwell Collins Pro Line 21 flight deck, which is fitted to aircraft such as the Cessna Citation XLS+ business jet, features a standby navigation display and engine gauges.
The 207B-1 was capable of 35 kilowatts of RF output in amplitude modulation mode, and 50 kilowatts in continuous wave mode. The transmitter was designed for land-based operation within the frequencies of 4 to 26 MHz and was contained within five sheet metal cabinets bolted together to form a single unit with a weight of 16,800 pounds.
