What are utility stations on HF?

This is a valid question, and one that can be answered using a bit of negative logic. If it isn't

  • Amateur Radio
  • CB
  • SW broadcast

Then it's considered a utility station.

This type of station has many different types; military, aeronautical, maritime even non-governmental organizations like the Red Cross all fall into this category.

This page represents a tiny fraction of the available services and topics. The single best reflector that covers this topic is the Utility DXers Forum reflector on the groups.io server. The Utility DXer's Forum webpage has an exhaustive set of links and pages covering a wide range of utility related topics.

This topic is covered in the Utility Listening Forum
