PSKMeter - KF6VSG pskmeter page, describing the hardware, software and firmware for a monitoring device for psk31 transceivers that automatically maintains the sound card level to give maximum drive to the transmitter without introducing distortion.

A Flexible Digital-Mode Interface - One interface, all the software—here’s how to do it simplyand inexpensively. QST article by Jim Mitrenga N9ART

A new method of radio direction finding Priority listing - A method of finding radio sources with antennas based on omni-directionality (the less directional the better coverage). Uses energy levels and some sophisticated math (encompassed in a free software download on the site) to find x,y,z coordinates of the fox relative to the center of your antenna array. Can be overlayed on a GPS map to help you locate in real-time.

PI-EL - The Windows program for designing and analyzing PI and PI-L networks by Tonne Software

Tower - Windows program for analyzing vertical antennas. This program shows the resistance and reactance to be expected looking into a cylindrical metallic tower over a perfect ground. It gives a useful approximation of the values to be expected in a real-world situation.

Elsie - Filter Design - Filter design software. Elsie is an uncommon commercial-grade lumped-element ("L-C") electrical filter design and network analysis program, directed toward the engineer or technician involved in that line of work.

SVC Filter - Filter design software. A program designed to expedite the design and analysis of lowpass (and highpass) filters with nearest 5% component values. SVCfilter is 32-bit Windows electrical filter design software nicely written to help the radio amateur, technician or engineer design and analyze lumped-element lowpass and highpass filters.

Meter - This meter scale drawing program is designed to have a computer do the hard work in making a precision scale for a d'Arsonval analog meter. The resulting scales will typically be nicer-looking than those found on many commercial meters.

Helical - A graphics-intensive bandpass filter program based on the helical resonator.

Quad - from Tonne Software - This graphics-intensive program designs and analyzes active quadrature ("90-degree") networks for use in SSB transmitters and receivers.

Numerical Electromagnet Code (NEC) Archives - The unofficial Numerical Electromagnetic Code (NEC) Archives, antenna analysis software

Pizza - This program allows both great-circle (polar) and rectangular projections of the world. The great-circle map is centered on any specified latitude and longitude (the "home" location). The rectangular projection is shown with the home longitude in the middle of the screen.

BCmap - This program shows a polar-projection map of the northern part of Region 2 (Western hemisphere) with the patterns of all AM radio stations in Canada, the United States, Mexico and Cuba, on a specified frequency, with the map centered on a user-specified "home" location.

DXSpider - DX Cluster - DXSpider is a clone of PacketCluster software that runs under several operating systems including Linux and Windows compatible with the AK1A program

RX-PSK31 - Easy to use Audio Spectrum- and PSK31 decoding program specially designed for SWL's who don't need TX or for anyone who just like to monitor PSK31 or analyse signals. Adjustable DSP and Spectrum settings for audio and frequency spectrum analasys or to set it for best decoding of PSK31 signals. By ON6MU

OpenBCM - The BayCom-Mailbox is an amateur radio/citizen band AX.25 Bulletin Board System with AX.25 store and forward capabilities. The software is available for Linux, DOS and Win-NT. OpenBCM is opensource and freeware.

BPQ32 - A user group established by John Wiseman G8BPQ/GM8BPQ and Ron Stordahl AE5E (ex N5IN) for BPQ32 - AX.25 NET/ROM compatible node software for Windows.

SEP Win - VHF Propagation Analysis Software for the Radio Amateur by K9SE

N9ZLE ICOM - CIV Software - IRC is a Free Radio control program for Icom radios using the CIV CT-17 or compatible interface. This program allows the use of different skins to display just about any radio from the IC746 to a secret agent watch. The program uses the new features available with the 746 and 756 to upload or save memories from your rig

AR8200 Computer Control Software - Ar8200 computer control software jaor is the ultimate in management for the aor 8200 mki, mkii and mkiii radio scanner. the software allows full function control, memory management, configuration and remote access of the radio.

CallSign Software - HamStationExtreme, hamradiostation and scopestation makers. CallSign Software provides a variety of Radio Control Packages to drive ICOM, Elecraft, and Ten-Tec's latest DSP based Transceivers and Receivers.

Diplexer - This program expedites the design of lumped-element diplexers using both the lowpass/highpass and the bandpass/bandstop topologies.

Class E - This program simplifies the design of the single-ended Class E amplifier. Operation is intuitive and encourages "tuning" and exploration.

RevLoad - This graphics-intensive program reveals the load on the output of a matching-network, based on measurements of the components in that network. Adjust the network (tuner) for a flat input, measure or look up the network component values and you will immmediately see the R and jX values of the load on the network, presented as both a schematic with the component values and as a Smith Chart normalized to the specified system impedance.
