Part 97 defines several categories of station control, and automatic control versus remote control is a distinction that matters a lot more than most hams realize, especially for anyone running a repeater, a hotspot, or a remote-operated station.
What Remote Control Means
Remote control means a control operator is actively controlling the station in real time from a location other than the transmitter itself, typically via an internet or radio link, actively making operating decisions and directly supervising transmissions as they happen. Operating your home HF rig remotely from a laptop while traveling is a classic example of remote control under this definition.
What Automatic Control Means
Automatic control means the station operates without a control operator actively present or directly supervising each transmission in real time, instead relying on the station’s own built-in logic to comply with the rules. A repeater is the classic example: it retransmits whatever comes in without a human actively monitoring and approving every single transmission, following pre-programmed logic instead.
Why the Distinction Matters
Part 97 places different requirements on stations depending on which category they fall into. Automatically controlled stations, like repeaters, need to meet specific technical requirements, such as automatic station identification and certain built-in safeguards, precisely because no human is actively supervising each transmission the way remote control assumes. A station legally operating under automatic control that does not meet these specific technical requirements is not in compliance, even if it functions perfectly well technically.
Where This Gets Relevant for Everyday Hams
- Running a repeater, even a small personal one, means understanding and meeting the automatic control requirements, not just plugging in a duplexer and calling it done.
- A DMR hotspot generally functions as automatic control equipment, similarly requiring compliance with the relevant technical rules.
- Remote HF operating from a laptop while traveling is remote control, requiring you as the control operator to actively supervise the station’s transmissions in real time, the same as if you were physically present at the radio.
The Practical Takeaway
If you are setting up anything that operates unattended, a repeater, a hotspot, a beacon, understand which control category it falls under and confirm your setup actually meets the corresponding Part 97 requirements, rather than assuming any working technical setup is automatically compliant.
