Temat: Uchwała 640 ITU

Ciekawe, czy w Polsce byłoby to do przeprowadzenia - aby w przypadku klęski żywiołowej Prezes UKE zezwalał na pracę na pasmach amatorskich - licencjonowanych stacji nieamatorskich i nawiązywanie łączności ze stacjami amatorskimi?

5.9 ITU Resolution 640

An important Resolution affecting Amateur Radio operations is Resolution 640 of the International Telecommunications Union (ITU)World Administrative Radio Conference (WARC), Geneva, 1979. Its proper title is, "Resolution No. 640, Relating to the international use of Radiocommunications in the event of natural disaster, in frequency bands allocated to the Amateur Service".

It is readily available as part of the ITU Radio Regulations edition of 1990 revised 1994, directly from the ITU.

The ITU considers that in the event of a natural disaster, normal communication systems, such as the 'phone system, TELEX, mobile phones etc. are frequently badly damaged by the disaster, for example by destruction of the telephone exchanges (on which so much depends), or the mains electricity (which powers electronic communications systems). Even if this is not so, then the system may become overloaded. This will happen because in a normal situation, much less than 5% of the users of a certain telephone exchange will normally be using it at the same time. Therefore the exchange, for reasons of economy, only has enough circuits to carry about 5% of the theoretical maximum calls. As not everyone making a call will be calling outside their town, there are only about 10% of the lines leaving a town as there are circuits provided in the exchange.

Now visualise the situation when every user tried to use the phone at the same time. Only 5% will get through. This situation is called Blocking, or overload. The situation is the same or worse for the mobile phone system, so you can see that you can't depend on the normally dependable phone system in a disaster.

Against this, rapid establishment of communication is essential to facilitate world-wide relief actions. As we shall see, arranging communications by radio is hardly rapid, it can take weeks to get the licences, frequencies, type approvals etc.

On the other hand, the Amateur bands are not bound by international plans or notification procedures, and are therefore well adapted for short term use in emergency cases. ITU considers that international disaster communications would be facilitated by temporary use of certain frequency bands allocated to the amateur service. Under those circumstances the stations of the Amateur service, because of their widespread distribution and their demonstrated capacity in such cases can assist in meeting essential communications needs. In fact there exists national and regional Amateur emergency networks using frequencies throughout the bands allocated to the Amateur service.

ITU considers that , in the event of a natural disaster, direct communication between Amateur stations and other stations might enable vital communications to be carried out until normal communications are restored. The significance of this is that normally, a radio Amateur would refuse to talk to a non Amateur station because his licence prohibits this by law. Amateurs know the law because one of the two theory papers he must sit to get his licence is on radio law. By this resolution, the Amateur is allowed to work you and traffic messages for you and from you, this is called 'Third Party Traffic'. However he may need reassuring of this because all of his transmissions must be entered into a log book, which will be inspected by a government official. Therefore you should state clearly that you are invoking Resolution 640 for the traffic, this should put his mind at rest. It is however assumed that you do have some or other licence from the host government for the Radio equipment you are using.

ITU is pragmatic enough to realise that The rights and responsibilities for communications in the event of a natural disaster rest with the administrations involved. This means that you should get permission from someone to use resolution 640 on their territory.

On the other hand, if no government exists, then they are hardly likely to send radio inspectors around to check you equipment, so in that case you can probably safely go ahead until such authority appears. The subject of 'Spectrum use in a political vacuum' is on the agenda for future conferences, but in the mean time, what you get away with depends upon how mature you are about your privileges.

ITU resolved that the bands allocated to the Amateur service which are specified in Radio Resolution 510 may be used by administrations to meet the needs of international disaster communications. Note that it is the government that has this permission not you. You don't have an absolute right to demand these privileges from the government, so you must use diplomatic language when urging them to get on with giving some kind of 'nod'.

The Resolution also states that such use of the bands shall be only for communications in relation to relief operations in connection with natural disaster. In theory this means that you can't invoke it in a war zone, but in practice that will depend as usual on the administration (or lack of it).

The Resolution goes further to state that the use of specified bands allocated to the Amateur service by non-Amateur stations for disaster communications, shall be limited to the duration of the emergency and to the specific geographical areas as defined by the responsible authority of the affected country. This seems obvious and fair. The amateur bands are highly overloaded normally, and so can't handle unnecessary traffic that could or should go by 'phone once the normal services are restored. Don't use it to save money, only if it is the only alternative.

ITU state that disaster communications shall take place within the disaster area and between the disaster area and the permanent headquarters of the organisation providing relief. This means that you can contact Amateurs in for example the UK, and ask them to relay messages to your HQ. You can even set up a station in your HQ if you can find an Amateur to operate it. Again, a reminder that such communication shall be carried out only with the consent of the administration of the county in which the disaster occurred. And that of the country where your HQ is situated.

There may already be existing networks of Amateurs to traffic information out of the disaster area, and they will be using up much of the spectrum for this. For you to duplicate this effort is very wasteful of your resources and spectrum so the Resolution makes the proviso that relief communication provided from outside the country in which the disaster has occurred shall not replace existing national or international Amateur emergency networks. The point is also made that close co-operation is desirable between Amateur stations and stations of other radio services which may find it necessary to use Amateur frequencies in disaster communications.

We disaster Relief service users may feel that we have righteousness on our side and that we should have right of way, but not so. Para 8 states 'that such international relief communications shall avoid, as far as possible interference to the amateur service networks'. Therefore you have no right to demand that another station gets off your channel. You could though ask him to move off explaining the reason by saying "QRT ( stop sending ) or QSY ( change frequency), we are a disaster Relief service working to Resolution 640", ( which he should have heard of ).

ITU then concludes by inviting administrations to provide for the needs of international disaster communications and provide for the needs of emergency communications within their national regulations. In the UK the Radiocommunications Agency (RA) does this by encouraging radio Amateurs to set up and practice emergency networks.
