Ky-57 Vinson
KY-57 VINSON Homepage Crypto KY-57 (VINSON) Index Voice encryption unit Enigma The KY-57 was a wide-band voice encryption unit that was developed in the USA during the 1970s as a replacement of the NESTOR cryptographic products, such as the KY-38. It was suitable for use with a Hagelin wide range of military radios and telehone lines. As part of the VINSON family of devices, it was the main Fialka crypto 'workhorse' of the US Army during the 1980s. Even today, many radios and voice encryption devices are still backwards compatible with the KY-57, that is also known as the TSEC/KY-57. The Siemens airborne version of the KY-57 is called the KY-58. Philips The KY-57 uses the NSA-developed Type-1 KY-57 voice encryption unit Nema SAVILLE cryptographic algorithm. When used in combination with a radio transceiver, such as the Racal SINCGARS non-ICOM RT-1439/VRC, the KY-57 STK allows signal fades or losses for up to 12 seconds without losing synchronization. Transvertex The KY-57 was eventually superceeded by the KY- Gretag 99 that offered newer - more advanced - Telsy cryptographic algorithms, but that was still backwards compatible with the KY-57. Later Tadiran SINCGARS ICOM radios, such as the RT-1523, had built-in KY-57 (VINSON) compatibility. USA USSR Both voice and data can be encrypted with the KY-57. Voice data is digitized using Continuous Variable Slope Delta modulation (CVSD), similar to other voice crypto systems of the same era, such as the UK Philips Spendex-10 , the Spendex 50 and the Telsy TS-500. -

KY-58 (Vinson)
KY-58 (Vinson) The KY-57/58 is a member of the VINSON family. The VINSON family consists of wideband secure voice (WBSV) units developed by the National Security Agency to provide line of sight half-duplex voice and data encryption at 16 Kbps. The KY-57/58 provides security for AM/FM, VHF, UHF, half-duplex PTT combat net radios and tactical wireline systems when used with the HYX-57. Also used by non-tactical users for high-level communications in the local wideband telephone networks and wideband satellite terminals. The KY-57 is the manpack/vehicular model and the KY-58 is the airborne/shipborne version. The KY-57/58 is certified to pass data up to TOP SECRET and accepts key from the family of Common Fill Devices and also incorporates remote keying. KY-57/58 production was completed in 1993. No further production is planned. KY-58 photo by Tim Tyler Tim Tyler comments."The photo above depicts the KY-58 unit inside a USCG HH-65C 'Dolphin' helicopter taken in September 2008. It is currently configured just for use on their 225-400MHz aircraft band radio. Supposedly, they're in the process of upgrading the HH-65 helos into an MH-65 (Special Ops capable) configuration which will have APCO P-25 compliant radios (with AES crypto, for talking to other DHS agencies) as well as ANDVT / KY-100 type crypto for communicating with the military-side of USCG ops".

High-Frequency Radiowa Ve Probing of the High-Latitude Ionosphere
RAYMOND A. GREENWALD HIGH-FREQUENCY RADIOWAVE PROBING OF THE HIGH-LATITUDE IONOSPHERE During the past several years, a program of high-frequency radiowave studies of the high-latitude ionosphere has been developed in the APL Space Department. Studies are now being conducted on the formation and motion of high-latitude ionospheric electron density irregularities, using a sophisti cated high-frequency radar system installed at Goose Bay, .Labrador. The radar antenna is also being used to receive signals from a beacon transmitter located at Thule, Greenland. This information is providing a better understanding of the spatial and temporal variability of high-latitude propagation channels and their relationship to disturbances in the magnetosphere-ionosphere system .

UNIT -1 Microwave Spectrum and Bands-Characteristics Of
UNIT -1 Microwave spectrum and bands-characteristics of microwaves-a typical microwave system. Traditional, industrial and biomedical applications of microwaves. Microwave hazards.S-matrix – significance, formulation and properties.S-matrix representation of a multi port network, S-matrix of a two port network with mismatched load. 1.1 INTRODUCTION Microwaves are electromagnetic waves (EM) with wavelengths ranging from 10cm to 1mm. The corresponding frequency range is 30Ghz (=109 Hz) to 300Ghz (=1011 Hz) . This means microwave frequencies are upto infrared and visible-light regions. The microwaves frequencies span the following three major bands at the highest end of RF spectrum. i) Ultra high frequency (UHF) 0.3 to 3 Ghz ii) Super high frequency (SHF) 3 to 30 Ghz iii) Extra high frequency (EHF) 30 to 300 Ghz Most application of microwave technology make use of frequencies in the 1 to 40 Ghz range. During world war II , microwave engineering became a very essential consideration for the development of high resolution radars capable of detecting and locating enemy planes and ships through a Narrow beam of EM energy. The common characteristics of microwave device are the negative resistance that can be used for microwave oscillation and amplification. Fig 1.1 Electromagnetic spectrum 1.2 MICROWAVE SYSTEM A microwave system normally consists of a transmitter subsystems, including a microwave oscillator, wave guides and a transmitting antenna, and a receiver subsystem that includes a receiving antenna, transmission line or wave guide, a microwave amplifier, and a receiver. Reflex Klystron, gunn diode, Traveling wave tube, and magnetron are used as a microwave sources. -
