Online propagation tools

The RSGB’s Propagation Studies Committee has a number of online tools to help you work out the best band and time to make a contact

Propagation tools available

RadCom Tools

For point-to-point monthly median HF propagation predictions to 28 different locations—some including long path—using user-defined mode, power, antennas.

• VOACAP-based
• ITURHFPROP-based

Radcom has printed predictions, based on ITURHFPROP and produced by Gwyn, G4FKH.

General HF propagation tools

For monthly median HF propagation predictions between any two points on the planet allowing full control over input parameters.
