COMMISSION'S RULES

Section E1C

Station Control: Definitions and restrictions pertaining to local, automatic and remote control operation; control operator responsibilities for remote and automatically controlled stations

What is a remotely controlled station?

  • A station operated away from its regular home location
  • A station controlled by someone other than the licensee
  • A station operating under automatic control
  • Correct Answer
    A station controlled indirectly through a control link

FCC 97.3(a)(38) Remote control. The use of a control operator who indirectly manipulates the operating adjustments in the station through a control link to achieve compliance with the FCC Rules.

Regarding the distractors, a station operated away from its home location is still being operated locally. When it's being controlled by someone other than the licensee that someone is still the control operator. Automatic control means that the station is controlled automatically -- with no control operator at the control point, as in the case of a repeater.

What is meant by automatic control of a station?

  • Correct Answer
    The use of devices and procedures for control so that the control operator does not have to be present at a control point
  • A station operating with its output power controlled automatically
  • Remotely controlling a station's antenna pattern through a directional control link
  • The use of a control link between a control point and a locally controlled station

Note that automatic control is not the same as remote control. With remote control, the control point (the point from which the station is controlled) is located remotely from the station and controls the station over a control link.

Automatic control is the only form of control of a station that allows operation when the control operator is not at a control point. The most common example of automatic control is a repeater. There is still a control operator, but they have configured the station for Automatic Control and it controls itself without them needing to be present at a control point. This is generally done using special devices or procedures allowing the station to control itself.

FCC 97(a) (6) Automatic control. The use of devices and procedures for control of a station when it is transmitting so that compliance with the FCC Rules is achieved without the control operator being present at a control point.

How do the control operator responsibilities of a station under automatic control differ from one under local control?

  • Under local control there is no control operator
  • Correct Answer
    Under automatic control the control operator is not required to be present at the control point
  • Under automatic control there is no control operator
  • Under local control a control operator is not required to be present at a control point

There is always a control operator when an amateur radio station is transmitting. With local control, the control operator is physically at the same location as the station and is controlling it from the control point there.

Automatic control is when the control operator uses devices and/or procedures to configure the station so that it can operate without an active control operator. There is still a control operator, but he or she is not present at the control point in all cases during station operation.

A common example of automatic control is a repeater.

When may an automatically controlled station retransmit third party communications?

  • Never
  • Correct Answer
    Only when transmitting RTTY or data emissions
  • When specifically agreed upon by the sending and receiving stations
  • When approved by the National Telecommunication and Information Administration

An automatically controlled station may retransmit 3rd party communications only if the emissions are RTTY (radio teletype) or data (such as packet).

When may an automatically controlled station originate third party communications?

  • Correct Answer
    Never
  • Only when transmitting an RTTY or data emissions
  • When specifically agreed upon by the sending and receiving stations
  • When approved by the National Telecommunication and Information Administration

The rule that confuses people on this one is: An automatically controlled station may retransmit 3rd party communications only if the emissions are RTTY (radio teletype) or data (such as packet).

HOWEVER: An automatically controlled station can never originate the third party communications.

The key word here is originate.

This question has been removed from the pool, since it was unclear.

Which of the following statements concerning remotely controlled amateur stations is true?

  • Only Extra Class operators may be the control operator of a remote station
  • A control operator need not be present at the control point
  • Correct Answer
    A control operator must be present at the control point
  • Repeater and auxiliary stations may not be remotely controlled

Except in the case of an automatically controlled station, all Amateur Radio stations must have a control operator at the control point when transmitting.

With a remote control station you might think that this is not true, but in actuality the place from which you remotely control the station is the control point.

What is meant by local control?

  • Controlling a station through a local auxiliary link
  • Automatically manipulating local station controls
  • Correct Answer
    Direct manipulation of the transmitter by a control operator
  • Controlling a repeater using a portable handheld transceiver

There are several types of control permitted for an Amateur Station. Local control is the simplest and most readily understood. It is simply control of a station directly, at the controls of that station, by a control operator.

Other types of control (for comparison, not for the answer to this question) include Automatic Control (such as a repeater) and Remote Control (such as controlling a station through an auxiliary link or controlling a repeater using a handheld.)

What is the maximum permissible duration of a remotely controlled station's transmissions if its control link malfunctions?

  • 30 seconds
  • Correct Answer
    3 minutes
  • 5 minutes
  • 10 minutes

Memory Trick: If your control link malfunctions, it cannot transmit more than 3 minutes. “3 strikes and you’re out!”

Real Answer: FCC 97.213(b)) Provisions are incorporated to limit transmission by the station to a period of no more than 3 minutes in the event of malfunction in the control link.

3M m on its side looks like the number 3. malfunction, minutes, m rotated

Which of these frequencies are available for an automatically controlled repeater operating below 30 MHz?

  • 18.110 - 18.168 MHz
  • 24.940 - 24.990 MHz
  • 10.100 - 10.150 MHz
  • Correct Answer
    29.500 - 29.700 MHz

A repeater may receive and retransmit only on the 10 m and shorter wavelength frequency bands except the following segments.

  • 28.0–29.5 MHz
  • 50.0–51.0 MHz
  • 144.0–144.5 MHz
  • 145.5–146.0 MHz
  • 222.00–222.15 MHz
  • 431.0–433.0 MHz
  • 435.0–438.0 MHz

29.500 MHz - 29.700 is the only answer that is Directly below 30MHz

What types of amateur stations may automatically retransmit the radio signals of other amateur stations?

  • Only beacon, repeater or space stations
  • Correct Answer
    Only auxiliary, repeater or space stations
  • Only earth stations, repeater stations or model craft
  • Only auxiliary, beacon or space stations

FCC 97.113(f) No amateur station, except an auxiliary, repeater, or space station, may automatically retransmit the radio signals of other amateur station.

An easy way to remember this is to focus on "automatically retransmit signals", or ARS; which happens to follow the order for (A)uxiliary, (R)epeater, or (S)pace stations.
