Propagation : Beginner's Guide
  • 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.

Propagation : Resources
  • Propagation on 630 Meters and 2200 Meters - This is a theoretical look at propagation on 630-Meters and 2200-Meters using ray tracing software. It expands on the brief discussion in the ARRL Handbooks. The Earth's magnetic field affects 630-Meter and 2200-Meter band propagation. Lower ionization reduces absorption, aiding low-frequency propagation. Differences exist between bands, limited daytime sky-wave propagation. Sunrise/sunset show promise, yet mechanisms are unclear. Ducting possible at night in specific conditions. Negative ions enhance propagation. Inefficient antennas and high man-made noise are anticipated. Groundwave propagation is significant on 2200-Meters.

Software : Logging
  • 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
