HF receivers are used to support which type of communications?

Explanation:
High frequency receivers are used to pick up signals that carry two broad kinds of information: voice and data. Voice is common on HF through modes like SSB, enabling real-time spoken conversations over long distances. Data transmissions use digital modes and HF modems to send computer-based information, emails, and files over long ranges. Morse code (CW) is a traditional mode on HF, but the question aims at the general types of communications supported, and voice plus data covers the common, modern use.
