Proxmark3 is a multi-purpose hardware tool for radio-frequency identification (RFID) security analysis, research and development. It supports both high frequency (13.56 MHz) and low frequency (125/134 kHz) proximity cards and allows users to read, emulate, fuzz, and brute force the majority of RFID protocols.

Along with the open-source tools, the Icom proprietary dsipsvd or "D-STAR IP Service Daemon" and a variety of crontab entries utilize a mixture of the local PostgreSQL and BIND servers to look up callsigns and "pcname" fields (stored in BIND) which are mapped to individual 10.x.x.x internal-only addresses for routing of both voice and data ...
PC-based vocabulary profiling software that includes the GSL: Heatley, Nation, and Coxhead's RANGE and FREQUENCY programs , including the GSL and the AWL as TXT files for vocabulary profiling Lextutor Vocabulary Profilers provided free by Tom Cobb includes several web-based vocabulary profilers, in which you can paste any text and the words are ...
Ansys HFSS (high-frequency structure simulator) is a commercial finite element method solver for electromagnetic (EM) structures from Ansys. [ 1 ] Engineers use Ansys HFSS primarily to design and simulate high-speed, high-frequency electronics in radar systems, communication systems, satellites, ADAS, microchips, printed circuit boards, IoT ...
Automatic Link Establishment, commonly known as ALE, is the worldwide de facto standard for digitally initiating and sustaining HF radio communications. [1] ALE is a feature in an HF communications radio transceiver system that enables the radio station to make contact, or initiate a circuit, between itself and another HF radio station or network of stations.
The tone spacing in frequency is 8000 Hz/256 = 31.25 Hz and the demodulator FFT has the resolution of 8000 Hz/512 = 15.625 Hz thus half of the tone separation. To adapt the system to different propagation conditions, the number of tones and the bandwidth can be changed and the time and frequency parameters are proportionally scaled.
High Frequency Data Link (HFDL) is an ACARS communications medium used to exchange data such as Aeronautical Operational Control (AOC) messages, Controller Pilot Data Link Communications (CPDLC) messages and Automatic Dependent Surveillance (ADS) messages between aircraft end-systems and corresponding ground-based HFDL ground stations.
