There are only three types of control: 1. Direct (operator at the control point) 2. Remote (operator at some other point controlling via some type of link) 3. Automatic (automatic systems that enforce legal operation)
Remote control can be implemented either over wires or RF or some combination. I can't think of any other possibilities and I don't recall anything in part 97 that mentions any. Direct and Remote control are available for any amateur station, but Automatic control can only be used with certain specific types of stations (repeater and auxiliary are among them). Most repeater trustees use a combination of automatic control (usually a microprocessor based controller with appropriate time-out timers, ID timers etc.) and RF remote control (usually in the form of a separate control receiver). Some trustees are not comfortable with RF remote control and insist on a land-line for control, though it is not required. Many times, a land-line is not available or is prohibitively expensive. I know of repeater sites in use that are many miles from the nearest available land-line. In these cases, RF remote and automatic control is all you can do. -- Keith McQueen [EMAIL PROTECTED] 801-224-9460 On 11/7/07, MCH <[EMAIL PROTECTED]> wrote: > > I guess that is where it is - in all parts.
