Finite difference program - This software is able to calculate the properties of odd shaped transmission lines. Particularly good in valve amplifier design, for aiding the design of transmission line resonators.

WINRLC - Simple freeware tool to calculate several kinds of HF filters. Use to calculate L-C and R-C band filters and bandpasses, L-C, L-R and R-C highpasses and lowpasses, coils and capacitors.

atlc - Arbitrary Transmission Line Calculator. - Unix or linux programme atlc calculates the impedance of electrical transmission lines of totally arbitrary cross section.

Radio Distance Software - This is a trivial program which calculates the distance and the bearing between two points. Points are either entered as geogr. data (Latitude/Longitude) or as qth-locator in the Maidenhead format (6 or 8 digits), as used in ham radio. Output is in degrees [°] for bearings, in Kilometer [km], US statute miles [mi] or nautical miles [nm] for distance

HamGrids - Windows application that will allow you to perform calculations with the popular Maidenhead Grid Square system. This grid system is used worldwide by amateur radio operators for many aspects of ham radio.

WinGrid - Calculates grid squares from latitudes and longitudes, the reverse, and calculates distances and headings from two sets of lat/long or grid square. Convert Grid Square to Lat Log and vice versa. Freeware for Windows

iDXSpot - DX Spots announced by speech in phonetics (or plain). Connect to the worldwide DX-Cluster via the Internet easily. Calculates distance and bearing between Grid locators and sends Grid & distance. Hot buttons to see DX-Spots on specific bands. Editable Hot buttons. Easy switching between favourite DX-Clusters.

TCalc - TCalc+ analyses the Noise and intermodulation performance of radio receiver front-ends.

FT-817 Commander - The ultimate free CAT program for the Yaesu FT-817

Ham Helper - Ham Helper is a tool that will help Ham Radio operators with many tasks. Features include UTC Time display, Callsign Country lookup, internet callsign lookup, band plans, W1AW schedule, bearing/distance calculation and more.

Frees - Calculates the freespace range of a radio-link. It is useful for radio amateurs, radio engineers and for SETI signal estimations. Calulation of parabolic dish antenna-gain is included.

HAMIC - The Ham Intelligent Calculator - HAMIC, is a program designed to simplify a number of calculations commonly used by HAMs. It is designed for the HAM radio hobbyist, but may be useful to others as well. HAMIC has a simple to use, but powerful graphical interface that allows solving simple circuits such as resistors in series or parallel, or more complex circuits such as L networks or T networks. As well, other calculations such as SWR and reactance conversions are supported. Windows shareware.
