Speedometers SWR Meters and Smith Charts
- Have wondered why a Smith chart has such strange grid lines. Believe it or not, there is a logical progression from Speedometers to Smith charts that will make the Smith grid crystal clear.

- Input (grid or cathode) and output (plate) tube resistances calculation according to its electrical characteristics, frequency, mechanical dimensions and working conditions.
- Inductance calculation for single layer, air-wounded coils and helixes up to about 800 MHz. Inductance calculations accuracy is around 1%. Also, coils with maximum Q for given inductance, resonant RF chokes, PI and T resistive attenuators calculations are provided. Skin effects, radiation losses and other minor side effects are not accounted in maksimum Q factor coils calculations. Program assumes using copper (Cu) enameled or silver (Ag) plated wire. Program is writen bilingual in English and Serbian by YU1AW
- Free program that interfaces most ICOM radios with the ILG radio frequencies database and lets you click a station in the database to tune your radio to the station, or scan the list looking for stations that are on the air.
- Ham Log Mapping software freeware for Windows,
displays a map showing the amateur radio grid squares contacted and logged in using a third-party logging program by: Bertrand Zauhar, VE2ZAZ
FREQ DB Icom
- Program that interfaces with a text file of frequencies plus other data and tunes your ICOM radio. You create this data yourself, and can use almost any data you wish. You use the program by clicking a station in the file to tune your radio to the station or net, or scan the list looking for nets that are on the air.
