DVOACAP-Python Wiki

Welcome to the DVOACAP-Python documentation wiki! This wiki provides comprehensive guides, tutorials, and reference materials for using and developing with DVOACAP-Python.

What is DVOACAP-Python?

DVOACAP-Python is a modern Python port of the DVOACAP HF propagation prediction engine, originally written in Delphi/Pascal by Alex Shovkoplyas (VE3NEA). This project provides an accessible, well-documented, and maintainable Python implementation of the VOACAP ionospheric propagation model.

Key Features:

  • Predicts HF radio propagation conditions
  • Calculates Maximum Usable Frequency (MUF), signal strength, and reliability
  • NEW: VOACAP-style propagation maps with Maidenhead grid overlay
  • NEW: Mode presets for WSPR, FT8, CW, SSB with proper bandwidth parameters
  • Includes interactive web dashboard for visualization
  • Integrates with modern Python scientific stack (NumPy, SciPy, Matplotlib)
  • Validated against original VOACAP reference data
