Abbreviation for kilo (SI prefix for 103). See International System of Units.

1. Abbreviation for kelvin(s). See thermodynamic temperature.
2. When referring to data storage capacity, 210, or 1024 in decimal notation; however this usage of an upper case K is deprecated.

1. In tropospheric radio propagation, the ratio of the effective Earth radius to the actual Earth radius. Note: The k-factor is approximately 4/
3.
2. In ionospheric radio propagation, a correction factor that (a) is applied in calculations related to curved layers, and (b) is a function of distance and the real height of ionospheric reflection.

A patching facility designed for patching and monitoring of balanced digital data circuits that support data rates up to 1 Mb/s.

A popular implementation of TCP/IP and associated protocols for amateur packet radio systems.

A computational algorithm that processes measurements to deduce an optimum estimate of the past, present, or future state of a linear system by using a time sequence of measurements of the system behavior, plus a statistical model that characterizes the system and measurement errors, plus initial condition information.

Kilobits per Second

Kilobytes per Second

Abbreviation for key distribution center.

A unit of thermodynamic temperature, taken as one of the base units of the International System of Units (SI). The kelvin is defined by setting the thermodynamic temperature of the triple point of water at
27
3. 16 K. Note 1: The kelvin was formerly called “degree Kelvin. ” The term “degree Kelvin” is now obsolete. No degree symbol is written with K, the symbol for kelvin(s). Note 2: In measuring temperature intervals, the degree Celsius is equal to the kelvin. The Celsius temperature scale is defined by setting 0 °C equal to
