LEARNING  OBJECTIVES and NOTES
2g Unattended operation
The terms of the Licence do allow unattended operation of radio equipment (including beacons) subject to certain rules.
“Unattended Operation” means the operation of Radio Equipment by the Licensee when the Licensee is in a different location to that where the Radio Equipment is located;

2g.1 10(1) 17(1)(ll) Unattended use
The Licensee may conduct Unattended Operation of Radio Equipment provided that any such operation is consistent with the terms of this Licence. Additional restrictions which apply to the Unattended Operation of Beacons are specified in Schedule 2 to this Licence.

10(2) 17(1)(ff) Unattended remote control
The Licence also allows remote control of radio equipment. For example you may have a station set up in the countryside with a good antenna system. Subject to certain rules this could be operated by you from another location, for example a flat in the middle of a city over the Internet.

Remote access is for your own use. You cannot provide general, unsupervised access to all Amateurs.

The communication link to the remote station must be secure to prevent other Amateurs and the general public using it. Security measures should take into account section 11(2). That is to say the messages transmitted by the remote equipment should not be encrypted to make them unintelligible.

The link to remote equipment must be failsafe to prevent unintended transmissions or transmission of a type not permitted by the Licence. For example if the link fails, the transmitter must not be left in permanent transmit.

10(3) Remotely controlled equipment is not for general use. Clause 10 does not permit the Licensee to install Radio Equipment capable of Remote Control Operation for general unsupervised use by other Amateurs.
As mentioned above remote operation is for personal use and should not be open for use by amateurs in general.

10(4) 10(5) 10(6) 10(7) 11(2) Remote control links

Key points about bands used for remote control of equipment:
  • They must be secure so that other amateurs cannot gain access (10.4)
  • They must be failsafe to prevent unintended operation (i.e. they should not be stuck in the transmit position if something goes wrong). They should not be able to transmit types not allowed by the Licence. (10.5)
  • Holders of Foundation and Intermediate Licences may only control the remote equipment using radio frequencies in the amateur bands above 30MHz.. The schedule provides information about restrictions in certain areas of the UK
  • Power for the link is restricted to 500mW pep e.r.p for Foundation and Intermediate Licensees. For holders of a full licence power is limited to that normally available on the band in use. This is set out in the Full Schedule.
  • Only where this Licence is a Full Licence, Full (Reciprocal) Licence, Full (Temporary Reciprocal) Licence or a Full (Club) Licence, the Licensee may make use of any communications links (including, for the avoidance of doubt, the amateur band allocations given above to establish the wireless communication links.
  • The use of licence exempt radio bands are another possible method of control. The power limitations of these bands must be observed.
