RF Exposure Calculator This program uses the formulae given in FCC OET Bulletin No. 65 to estimate power density in the main lobe of an antenna, with use of the EPA-recommended ground reflection factor as an option. This program is intended for approximate far-field calculations. It may overestimate the actual field strength of high-gain antennas in the near field (within several wavelengths of the antenna). However, it may also underestimate the strength of fields that may be encountered in hot spots in the near field. No computer program can accurately predict where wiring or reflective objects may create hot spots in your particular installation.

FDLog Software This site is the home for the FDLog Field Day Logging Software. This program interacts with each Field Day station operator and synchronizes the log database across multiple computers via the (usually wireless) network. It cohesively ties the whole Field Day site together and facilitates not only logging but coordinating operations and band occupation. It runs on Windows, Linux and Macintosh using Python.
EchoLink EchoLink® software allows licensed Amateur Radio stations to communicate with one another over the Internet, using streaming-audio technology.
