Superfast analyzer for audio and radio signals. Examining radio signals is the original idea of Analyzer2000. Simply connect the AF-output of your receiver to the input of your soundcard and see, what you hear. Use SSB and you will have a feeling like using an expensive IF panorama adapter. Support for this version has been discontinued.

Shareware dual channel audio spectrum analyzer for Windows 2000/XP which can provide either a scrolling time-frequency display or a spectrum analyzer scope display in real time for any sound source connected to your sound card. Can be used for MTHELL, QRSS and DFCW by R S Horne

This resource provides access to the 59+ software collection, specifically highlighting the **59+ CW** module. The software enables the generation of Morse code signals for transmission through a COM port to a transceiver, or for audio output via a computer speaker, facilitating both keying and listening practice. Users can customize various parameters, including CW speed, tone frequency, dash/dot ratios, and PTT line delay, alongside defining keyboard shortcuts for common QSO fields such as callsign, QTH, name, and RST. The collection also includes the 59+ Logbook, which operates smoothly on Windows XP according to testing notes, though the CW application experienced startup issues on the same OS. The software was originally designed for older Windows operating systems, specifically Windows 95, 98, ME, and 2000. It is noted that the original idealog.net site is no longer active, and development for the 59+ suite appears to be discontinued. Analyzer and converter modules within the collection require registration and do not function in trial mode.

AEA Wireless Director Software Series turns PC's (running Windows 95/98/2000/ME or NT) into powerful tools that expand the use and power of SWR, Return Loss and Complex Impedance Analyzers.

HamVNA presents an alternative Vector Network Analyzer (VNA) software tailored for the Hermes SDR RX/TX board, enhancing its utility for analyzing antenna systems and radio circuits. The software processes measurement data from two distinct sources: direct acquisition via the Hermes hardware, leveraging fixtures like Sam Wetterlin's Series Fixture or reflection bridge, or by importing existing TouchStone format files (*.s1p, *.s2p) from other VNA hardware. It operates on Win2000/WinXP/Vista/Win7 platforms, supporting both 32 and 64-bit architectures. The program incorporates standard Open-Short-Load calibration for reflection mode and Short Circuit calibration for transmission mode, with the capability to save and reload calibration data. A key distinguishing feature is its RLC Fit function, which automatically generates an equivalent RLC circuit matching the impedance-vs-frequency curve of the Device Under Test (DUT), a capability noted as unique among VNA software. This function allows control over circuit complexity via an 'Order' slider. HamVNA also supports remote calibration, enabling the removal of coaxial cable effects from measurements for clearer analysis, as demonstrated with an 80m vertical antenna example. The software is an open-source project, distributed under the MPL v.2.0 license, with both the installation package and source code available for download.
