Interesting resources provided here includes, Solar images, a text 3 day solar geophysical forecast, a 3-days Solar X-Ray flux plot updated evety 5 minutes, The Satellite Environment Plot, combines satellite and ground-based data

Antenna Model - Commercial software for the analysis of wire antennas. runs under most Microsoft 32-bit Windows operating systems—Windows 98/ME/NT4/2000/XP Analyze most wire antennas in free space, over perfect ground, or over real-world grounds with the conductivity and dielectric constant you specify. You describe the antenna to the program in easy-to-use spreadsheet-style input window

Beacons - The W6AMT Beacons is a Windows program which automates the collection of radio propagation data. HF data is collected by monitoring the worldwide network of NCDXF / IARU HF beacons.

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.

jLog - jLog is a modern Freeware Ham Log program that can run on all major platforms, e.g. Mac OS X, Mac OS, Linux/Unix, Windows, etc. It offers a nice, clean interface and allows efficient entry of QSOs. Import or Export of data using the standardized ADIF 2 format is possible to easily exchange data with any other decent Log program. Built-in CW Keyer, CAT control for many popular, rigs, DX Cluster tracking, call lookups

FreqTweak - FreqTweak is a tool for FFT-based realtime audio spectral manipulation and display for Linux. It provides several algorithms for processing audio data in the frequency domain and a highly interactive GUI to manipulate the associated filters for each. It also provides high-resolution spectral displays in the form of scrolling-raster spectrograms and energy vs frequency plots displaying both pre- and post-processed spectra.

The KB6IBB Utilities for Palm OS - designed for the ham radio operator or radio scanner hobbyist. It houses four databases that organize your frequency lists. EDACS Trunk - A database that houses the entire EDACS ID table. Conventional - A database that houses lists by channal number. Radio Call Log - A database that allows the user to log calls/notes. Ham Radio Repeaters - A database for ham radio repeaters.
