[edit] Description
In many ways remote base stations controlled by radio resemble repeaters but do offer many additional features. Remote base stations are usually run and maintained by individual hobbyists or clubs, but unlike repeaters they are not usually open to any and all amateur radio operators. A remote base station is one type of station where the primary control point is not at the station location.
[edit] Usage protocol
When using a radio link, remote control of an auxiliary remote base station consists of sending the primary signal (phone or data) along with some form of control signals, such as DTMF tones, to another station to change is operating parameters; turning it on or off, changing frequencies or transmitting power levels, rotating antenna, etc. These control signals are considered to be one form of primary control of the station, the control of those parameters for which the station licensee and/or any other control operators are primarily responsible.
[edit] Frequency sharing
Despite not being open to the general Amateur radio public, radio controlled remote base stations do not own the frequency on which their control signals are sent and they do still have to share the use of any frequency with the rest of the Amateur radio community.
[edit] Frequency allocation
In the United States, all Amateur radio remote base station auxiliary operation must occur on frequencies above 222 MHz. This means that the control link must be above 222 MHz. However, a remote base may have a down-link on any frequency. In Switzerland, remote operation of an amateur radio station via internet is legal and approved by ofcom.
