HF Propagation Simulation: Variation of Time on all QRP Frequencies

In this post I show some video results of my Voacap simulations for HF propagation: the time has been varied (0-23h).

Simulation Parameters

  • Antenna: isotrope
  • Mode: cw (required SNR for circuit reliability calculation: 24 dB)
  • Power: 50W
  • Transmitter location: JO40DA
  • Month: July
  • SSN: 72.8
  • Frequencies: QRP frequencies on all ham bands…
