HF Frequencies

shoc HF Frequencies Monitoring Results

Request Info

An example application in which a receiver scans the spectrum with go2MONITOR and the data is then published on a website using the “shoc Reporting Tool”.

Info

  • Frequencies in kHz
  • We scan with 800 kHz bandwidth and 8 decoders from 3-28 MHz (excluding amateur radio and broadcast ranges) and receive around 30,000 classifications and 2,500 decoded signals per day
  • The output of notes and decoder data is limited to a few characters to ensure data privacy.
  • We select the few published data according to our needs, as this is only a demo, other fields in the database can also be mapped to the report.
