Wfview is a program that allows many modern Icom ham radio transceivers (such as the IC-7300, IC-9700, IC-7610, IC-R8600 and many others) to be controlled via a computer. wfview shows the gorgeous spectrum display on whatever display is connected, including projectors, touch screens, and TVs. wfview allows for full radio control from a computer keyboard and basic control from a numeric keypad. It works under Windows, Linux and MacOS
The standard J-Pole antenna is a end fed 1/2 wavelength antenna, in this article is explained also how to build an expanded Super J Pole that provides about 4.5 dbd gain. These antennas can be built from EMT electric conduit pipe
Transmission lines have many uses other than simply transferring RF power from one point to another. Impedance matching, baluns and filters are probable the most common of these.
Calculate distance, bearing and more between Latitude/Longitude points. This page presents a variety of calculations for latitude/longitude points, with the formulas and code fragments for implementing them.
Antenna most often used by Hams around the world. Inexpensive, effective and easy to build, what more could anyone ask for in a home made antenna.
A simple and effective sleeve type balun is easily built. This Balun can be adapted to any band. While the dimensions are not critical ( +/- 10%), it is still basically a mono band device
A log utility for WSJT-X and JTDX Provides functionality missing from WSJT-X and JTDX and more
