• HF DXView Propagation Map - This map shows real-time radio propagation from stations operating on 11 bands between 1.8 and 54 MHz in the amateur radio service. The display shows world-wide activity from the last 15 minutes and is automatically updated about every minute. Data for the map is gathered from several online sources: WSPRnet, Reverse Beacon Network (CW, FT4, FT8), PskReporter, and DX Cluster.

• Exploring the Spectrum From HF to UHF Frequencies - During radio's early days, high frequencies were under 30 MHz due to technical limitations. As understanding grew, components improved, allowing for higher frequencies like VHF and UHF up to 3 GHz. The HF band's long wavelengths provide unique propagation challenges influenced by solar activity. VHF and UHF bands face diffraction and reflection issues but offer diverse applications, from amateur radio to 5G and GPS technologies.

• VHF APRS Propagation Map - VHF – Based on realtime APRS reports. This map shows real-time radio propagation from stations operated near 144 MHz. It uses data gathered by Automatic Packet Reporting System-Internet Service (APRS-IS) from packet stations in the amateur radio service. The map shows activity from the past hour. Paths are smoothed to create a color-coded footprint indicating the distance VHF signals are likely to be traveling.

• SWLog - Shortwave and Amateur Radio Log (SWLog) is a modern suite of applications that provide logging and remote control for amateur radio and shortwave, utility, and broadcast listening. SWLog has been continuously improved and expanded since it was first released in 1988. SWLog is a suite of products that provides logging, radio control, GPS synchronization, QSL management, reporting, and propagation prediction. Program schedules from HFCC, ILGRadio, AOKI, ADDX, SWSkeds, EiBi, and others are leveraged for broadcast reception. Call sign lookups and remote logbooks are integrated with ClubLog, eQSL, QRZ, Ham365, HamQTH, and LoTW. SWLog provides Android and iOS applications for logging on the go as well as web servers for logging and remote control from anywhere. SWLog works on Windows, Linux, iOS and Android
