Licensing Conditions for Amateur Radio Stations - text out of date


§ 1
Purpose and Extent of Validity

(1) The Licensing Conditions for Amateur Radio Transmitting Stations (henceforth only "licensing conditions") determine the conditions according to which an amateur station may be established, operated and kept.

(2) The holder of the licence is obliged to acquaint all persons who are to serve the licensed station or come into contact with it with the contents of the licence and with the licensing conditions and to ensure that these are observed.

§ 2
Licence for Establishment and Operation

An amateur radio transmitting station (henceforth merely "station") may be established and operated only on the basis of a valid licence.

§ 3

(1) The holder of the licence is responsible to the licensing body for the establishment and operation of the station in accordance with the valid licensing conditions, including ensuring the station against abuse. If the holder of the licence is a legal entity, then this responsibility is taken over by the Chief Operator (CO) entered on the licence by the licensing body.

(2) The Chief Operator must have his own valid licence, signs correspondence and ensures contact with the licensing body.

§ 4
Documents of Amateur Station

(1) In every station the following documents must be available:

  • a) licence,
    b) station logbook (there may be two, one for SW and the other for VHF bands, in each of these, however, the existence of the other must be recorded),
    c) in the stations of legal entities a list of operators.

(2) When working in a temporary (mobile) workplace the licence or a verified copy of it must be available. In the case of stations of legal entities there must also be the written permission of the chief operator, including indication of the period for which the permission is given.

(3) The holder of the licence must take the necessary measures to see that all the documents are safe from damage, loss, theft and abuse. If such a matter nevertheless occurs it must be reported immediately in writing to the licensing body. If the licence has been damaged, lost or stolen it is necessary to apply at the same time for the issue of a duplicate and to pay the administrative fee for its issue.

Operator's Classes
§ 5

(1) Operators of amateur stations are divided into for operators' classes: A,B,C,D.

(2) Operators of Class A may operate a transmitter with an output up to 750 W and work in the bands given in Table No.1, including the given types of operation. Operation with an output over 300 W must be announced to the licensing body. The provision also applies for the stations of legal entities.

(3) Operators of Class B may operate a transmitter with output up to 300 W and work in the bands given in Table No.1, including the given types of operation.

(4) Operators of Class C may operate a transmitter with output up to 100 W and work in the bands given in Table No.2, including the given types of operation.

(5) Operators of Class D may operate a transmitter with output up to 100 W and work in the bands given in Table No.3, including the given types of operation.

§ 6

(1) In a case where there occurs from some workplace interference with other radiocommunications services or radio or television broadcasting, then the licensing body may stipulate limiting conditions.

(2) In substantiated cases the licensing body may permit:

  • a) a higher output,
    b) other types of operation than those listed in the tables,
    c) other bands than those given in the tables.
Operation of Amateur Stations
§ 7

(1) Amateur stations serve for the self-education, technical studies or sports activity of radio amateurs.

(2) The intermediation of information through an amateur station may not be a source of property gain.

(3) Unless stipulated otherwise by Czechoslovak regulations for amateur stations, then the operation of amateur stations is governed by the ITU Radio Regulations which is available for inspection in licensing bodies.

§ 8

(1) Licence holders have the right to establish, operate and keep the radio transmitting and receiving equipment necessary for the activity of an amateur station.

(2) On the basis of a licence it is also possible to have other stations intended for reconstruction as amateur stations. These may not, however, be operated, even on a trial basis.

(3) Licence holders and establishers of stations are obliged to safeguard amateur stations against theft and abuse, including the possibility of their being put into operation without the knowledge of the licence holder.

§ 9

Licence holders and the operators of stations of legal entities may make connection with other amateur stations or with stations permitted contact with amateur stations.

§ 10

(1) In the list of operators of a station of a legal entity the CO will keep a list of members with their own licences or of approved operators to whom he issues permanent consent to operation of the station, including the listing of operators'classes.

(2) Operators without their own licence but recorded in the list of operators may operate the station under the supervision of the Chief Operator or of recorded licence holders only in classes C or D. The supervising operator is responsible for operation. Short-term guest operators are merely recorded in the station logbook.

§ 11

(1) Amateur stations may, with the consent of the licence holder and under his supervision, be operated in classes C and D even by beginner operators over the age of ten years. Every such operator must be entered in the station logbook, but for a maximum period of two years. The licence holder is responsible for operation and is obliged to inform the licensing body in advance of this fact.

(2) Amateur stations may, with the consent of the licence holder and under his supervision or the supervision of another licence holder, be run even by amateur station licence holders from other states within the range of their operators' class. In normal contacts they must also give their own domestic call signal after their name.

(3) Foreign nationals who are holders of CEPT licences use a call signal in accordance with the recommendations of CEPT.

Content of Transmissions
§ 12

(1) Amateur stations are allowed to be used only for the transmission of messages which, due to their significance, are not usually transmitted by a uniform telecommunications network and concern radio amateur activity and radio amateurs.

(2) All messages may be transmitted only in clear speech, possibly with the use of international codes and abbreviations. At the beginning and end of each contact the complete calling signs of both communicating stations must be used in the type of operation in which they are working during the contact. If the contact lasts longer than five minutes the operator must include at least his own call signal not later than after five minutes. When participating in radio amateur competitions, contests and expedition operation it is not necessary to give both signals.

(3) In cases of threat to human life, in natural catastrophes and for other urgent reasons of public interest it is possible to use amateur stations for the transmitting of information in order to avoid danger immediately threatening. It is, however, necessary to make a record of this in the station logbook.

(4) For Amateur Radio Direction Finding (ARDF) it is possible to transmit only the internationally recognised symbols MO, MOE, MOI, MOS, MOH, MO5 in the bands given in Table No.4. These stations may also be operated by a person instructed by a licence holder. The licence holder is, however, responsible for operation.

§ 13

It is forbidden to transmit:

  • - messages containing facts which form the subject of state, economic and service secrets or other obligation to silence set by the Law,
    - messages and programmes which are in the nature of advertisement or radio broadcasts,
    - vulgar and obscene expressions,
    - messages and information for third persons not connected with radio amateur activity,
    - without giving one's own call sign.
§ 14

All operators are obliged to observe telecommunications secrecy regarding the information which they have caught and which are not intended for them, with the exception of facts which they are bound to declare according to valid Czechoslovak legal regulations.

Station Logbook
§ 15

(1) In all amateur stations there must be kept at least one station logbook which may not be destroyed until one year after the last entry without the consent of the licensing body or must be handed over to the licensing body.

(2) The logbook must have pages numbered in advance and must be firmly bound to limit the removal of pages. It must be recorded which station it belongs to. The first page in the logbook is reserved for the records of control bodies and the chief operator in the case of the station of a legal entity.

(3) In the logbook of an amateur station are recorded in particular:

  • a) the date, frequency band used, the call sign of the other station (in the case of work through a repeater the call sign of the repeater is enough), the time each contact begins and, if it is longer than ten minutes, when it ends,
    b) the times of the beginning and end of transmission if there has been no contact for some time,
    c) when transmitting from a temporary or further workplace also the position of the station,
    d) in the operation of a "mobile" it is enough to give the time of beginning and ending operation and the route from which transmission occurred.

(4) In the logbook of a station of a legal entity there is entered, apart from the above information:

  • a) the call sign or name of the operator who made the contact recorded,
    b) the call sign of the operator under whose supervision the operator made the recorded contact.

(5) If the data given in sections 3a and 3b is recorded on some memory medium then it is sufficient to enter in the logbook instead of this data only the times of beginning and ending transmission and the date. The licence holder is obliged to keep the memory media without change of content for at least one year from the day they were established or from the day of the contact.

§ 16

In participation in radio amateur contests and competitions the following exceptions are permitted:

  • a) the logbook of a competition or a copy of it may be kept as a separate numbered appendix to the station logbook, in which case it is enough to give only the name of the competition, date, time, situation of the station while transmitting from other than the permanent location, the number of the appendix and the number of pages,
    b) in the case of a station of a legal entity it is necessary to give also the call signs or names of the operators, including the call sign of the supervising operator.
Transmitting Elsewhere than from Permanent Situation
§ 17

(1) The licence holder may permanently keep and operate a station only at the locations given in the licensing certificate, possibly in other locations approved in advance by the licensing body, with the licensing body determining the method of use of data "/p". In the case of a permanent change of the location the licence holder is obliged to apply to the licensing body within seven days for a change to be marked in the licensing certificate.

(2) The licence holder may operate the station from a temoprary location without reporting this. He then adds the information "/p" or "portable" to his call sign.

(3) The licence holder may transmit from a mobile medium, in which case he adds "mobil" or "/m" to his call sign.

§ 18

Operation on Czechoslovak ships and aircrafts must be expressly permitted and the consent of the owner of the ship or aircraft is necessary for this.

§ 20

Undesirable radiation of transmitters outside the minimal ecessary bandwidth and undesirable radiation of receivers must be kept at the lowest value achievable, in keeping with valid Czechoslovak State Norms, the ITU Radio Regulations and the recommendations of the CCIR.

§ 21

(1) All test transmission, with the exception of the adjustment of antenna circuits of the transmitter, must be made into an dummy load.

(2) During a change in transmission frequency (re-tuning) there must not be any hf energy radiated by the antenna, with the exception of satellite operation.

§ 22

Transmission equipment (with the exception of equipment with output of less than 5 W) must be ended with an assymmetrical output of impedance between 50 and 100 W. The owner of the transmitter must also own a further antenna connector foroccasional use in measurement of the transmitter by the licensing body.

(2) Operators of amateur stations classified according to the licensing conditions of 22nd January 1979 in operators' classes A, B, C and D continue to be classified in these classes. Exceptionally permitted increased outputs remain valid until 1st January 1993. The validity of certificates for defence sports ends on 1st January 1993.

(3) In the case of possible changes in licensing conditions licence holders are obliged to make any changes to the equipment of amateur stations at their own expense.

(4) The Licensing Conditions for the Establishment, Operation and Keeping of Amateur Radio Stations, issued as a supplement to Measure No.30/1979 of the Bulletin of the Federal Ministry of Communications No.7/1979, are abolished.
