Welcome to the High Frequency Radio Signal Documentation Effort

Dedicated to documenting and reporting all signals!

Basic rundown

The HFRSDE is an international group made up by hobbyist listeners of HF, or shortwave, radio.
HF is the frequency range between 3-30 MHz which has special propagation characteristics to allow long distance communication.
This propagation ability is used by broadcasters, amateur radio operators, weather stations, and even military or diplomatic communications.
Seems interesting?

Then get to tuning and start documenting!
