1260-1300 MHz (amateur 23 cm band). 240-250 GHz (ham radio 12 cm band). This is a European grid. For the Russian grid, respectively, the last digit is "0".

For example, 27.155MHz - C16E, 27.150MHz - C16R.

Of the useful channels (in relation to Moscow) - ZcE, 9cE, 19cE, 21dE.

These are emergency channels, there are dispatchers who report and receive messages about traffic jams and accidents. Information about road accidents and other emergencies is best transmitted in channels ZsE ("Petrovka") or 9sE (Rescue Service).

The 9cE channel is allocated for the transmission of traffic accidents and other emergencies only. If you register with the Scream service (Petrovka, ZcE) or with the Rescue Service (19cE, 21dE, registration is free, but required), then the dispatcher can be asked to call by phone and send something or use it all as a pager (you can call control room and ask to transfer information for the person you need (of course, if he has a CB station).

The Polet-27 (9dE) service works similarly, only free of charge. And in other cases, it’s just your own connection, leaving the city, communication between cars, etc. There are channels that are occupied by a kind of interest clubs (to some extent, this is Polet-27, since it is organized by Association-27) and certain districts of Moscow.

Allowed channels (40 channels each in grids C and D) are fairly clogged, and additional grids are empty (A, B, E, F - if you really want, you can work in them, everyone pretends that they don’t notice this violation)

VHF

Amateur VHF frequencies:

  • 144-146 MHz - NFM USB CW DATA (for NFM step 25).
  • 145.025, 145.625 inverse repeater (Dmitrov).

  • 430-440 MHz - the same, part of the frequencies is sold to trunk operators.

Note. As a rule, the reception and transmission frequencies of amateur radio repeaters (repeaters) have a discrepancy relative to each other by 600 kHz. This parameter is also programmed by the manufacturer in the Kenwood TH-F7 transceiver.

Moreover, if the receive frequency of the repeater is 145.750, then its transmission frequency will be -600 kHz, that is, 145.150 MHz .. In inverse repeaters, everything is exactly the opposite.

The Kenwood TH-F7 transceiver also allows you to work with inverted repeaters; for this, the transceiver is reprogrammed from the keyboard so that the R indicator lights up on the display (see section 3.12).

Permitted VHF frequencies for radio amateurs their purpose

I often get questions from hams about frequency assignments on the VHF band. The fact is that the number of frequencies is limited and some of them are reserved for certain types of connections. Also, part of the frequencies are allocated for the needs of creating repeaters. For this reason, novice radio amateurs are afraid to take a specialized frequency and get hit on the ears. In order not to often answer these questions, I will give a table for the VHF band.

The band 144 to 146 MHz is allocated to the amateur radio service on a primary basis. Radio amateurs of the fourth category have the right to operate at these frequencies with a power of 5 W, the second and third at 10 W, and the first category at 50 W (for EME and MC communications of the first category it is allowed to use up to 500 W).

Frequency range (MHz) Bandwidth (kHz) Types of modulation and purpose (MHz)
144,000-144,110 0.5 kHz Telegraphy only. Predominantly EME telegraphy. The telegraphy calling frequency is 144.05 MHz. The frequency for MC communication without prior agreement is 144.100 MHz. Frequency band 144.0025 MHz - 144.025 MHz - primarily for space communications (space-to-Earth).
144,110-144,150 0.5 kHz Narrowband types. Predominantly digital narrowband EME modes. PSK31 activity center - 144.138).
144,150-144,165 2.7 kHz Telegraphy, OBP, digital types. Mostly digital types of EME.
144,165-144,180 2.7 kHz Telegraphy, OBP, digital types. Mostly digital types. The calling frequency of digital modes is 144.170 MHz.
144,180-144,360 2.7 kHz Telegraphy and OBP. The calling frequency of the OBP is 144.300 MHz. the frequency band for MC OBP communications without prior agreement is 144.195-144.205 MHz.
144,360-144,399 2.7 kHz Telegraphy, OBP, digital types. The frequency for FSK441 communications without prior agreement is 144.370 MHz.

It turns out that for direct communication in frequency modulation, frequencies from 145.206 MHz to 145.594 MHz are allocated. Grid step 12.5 kHz. This table was compiled in accordance with the decision of the SCRF dated July 22, 2014 No. 10-07-01.

Often in the characteristics of radio stations it is indicated as operating ranges VHF And UHF Consider what it is and what is the difference between them.

These abbreviations denote the two most common VHF communication bands.
the VHF range corresponds to the section from 136 to 174 MHz
the UHF range corresponds to the section from 400 to 512 MHz

In everyday life, radio amateurs also call these ranges "two" (VHF) And "seventies" (UHF), such names are given to these bands in accordance with the wavelength, which for VHF is about 2 meters and for UHF about 70 centimeters.

VHF- a range in which there are sections reserved for many government agencies, space communications and radio amateurs.

The main advantage of this range in comparison with UHF is a large communication range, especially outside the city. Walkie-talkies of this range work perfectly both in rural areas, in the forest, and in multi-storey buildings. The disadvantages of working in this frequency range include the absence of license-free areas, a relatively small area allocated for radio amateurs - from 144 to 146 MHz on a primary basis.

Due to the fact that these are quite low frequencies, effective antennas for this band are larger than for UHF, and in the case of walkie-talkies this is a significant problem that limits the use of VHF when working with portable radios. And of course, you can’t work on it without having a radio amateur category!

Below is a table with the frequency grid allocated for amateur radio communications. According to the decision of the SCRF dated July 22, 2014 No. 14-26-04, the range from 144 to 146 MHz is allocated to the amateur radio service on a primary basis. Radio amateurs of the 4th category have the right to operate at these frequencies with a power of not more than 5 W, the 2nd and 3rd by 10 W, and the 1st category by 50 W (for EME and MC communications of the first category it is allowed to use up to 500 W ). For voice communication with frequency modulation, frequencies from 145.206 MHz to 145.594 MHz are allocated.

Frequency range (MHz)Bandwidth (kHz)
144,000-144,110 0.5 kHzTelegraphy only. Predominantly EME telegraphy. The telegraphy calling frequency is 144.05 MHz. The frequency for MC communication without prior agreement is 144.100 MHz. Frequency band 144.0025 MHz - 144.025 MHz - primarily for space communications (space-to-Earth).

UHF- is considered a range "for the city" and allows you to get a reliable connection in high-rise buildings. Ideal for establishing communication over relatively short distances, due to the high frequency of the antennas of portable radios in this range, they are compact in size without sacrificing efficiency. But at the same time, this range is not suitable for open spaces and forests due to greater attenuation in the forest and poor ability to bend around the terrain compared to VHF.

According to the decision of the SCRF dated July 22, 2014 No. 14-26-04, the range from 430 to 440 MHz is allocated to the amateur radio service on a secondary basis. Radio amateurs of the 4th category have the right to operate at these frequencies with a power of not more than 5 W, 1st, 2nd and 3rd no more than 10 W (at frequencies from 433 MHz to 440 MHz), Also radio amateurs with 1st category is allowed to operate at 500 watts in a limited range (for EME and MC communications). At frequencies of 430.000-433.000 MHz, you can only work with a power of not more than 5 W for all categories without exception.

As can be seen from the frequency table below, there is much more free space on UHF allocated for amateur communications than on VHF, which also indirectly affects the predominant use of this range in large cities.

Also, do not forget that there are two unlicensed bands on the UHF frequency section

Information has surfaced on an agenda item for the 2023 World Radiocommunication Conference (WRC-23) that proposes consideration of the 144-146 MHz frequency band, including a possible redesignation as an application as a core band for the aeronautical mobile service, and few people objected at a meeting of the European Conference of Postal and Telecommunications Administrations (CEPT). The Team A project group where this issue was considered is responsible for some aspects of the CEPT WRC positions and the meeting was held June 17-21 in Prague, Czech Republic. The proposal submitted by France aimed at reassigning the 144-146 MHz amateur radio band will be part of a broader consideration of the aeronautical mobile bands. Another issue raised at the meeting was the sharing of the 1240-1300 MHz amateur radio band with the European Galileo GPS system.

“We have heard that only one administration (Germany) opposed the proposal to put the 144 MHz amateur band on a secondary basis – and no other,” said a spokesman for the UK Microwave Group after the meeting. Otherwise, this agenda item would have been rescheduled for the CEPT Conference Preparatory Group (CPG) meeting in August.

The International Amateur Radio Union (IARU), which was represented at the Prague meeting, expressed "serious concern" about any proposal that would include consideration of the 144-146 MHz band from an aeronautical mobile aspect in the proposed agenda item. Moreover, at the conference they intend to consider the issue of reassigning the entire 2-meter band in the 1st ITU Region. IARU is committed to making every effort to fully protect the interests of amateur radio stations and to enlist the support of the necessary regulators for their representation.

IARU Region 1 President Don Beattie, G3BJ, stated ahead of the meeting that the IARU will "vigorously promote its opposition within the Regional Telecommunications Organizations (RTOs) and the International Telecommunication Union (ITU) to ensure that that this band will remain the main one for radio amateurs.

The 144-146 MHz band in the worldwide frequency allocation is the only VHF band assigned to the amateur and amateur-satellite services on a primary basis. This widely used segment of the amateur radio bands is used by a large number of users, repeaters and satellite stations, including the ISS.

According to the minutes of the meeting, the proposal does not justify the redefinition of 144-146 MHz and the IARU considers that sharing with airborne systems is likely to be difficult and will limit the development of the amateur and amateur-satellite services in this band. The IARU recommended that alternative proposals be developed that could provide additional radio spectrum for aeronautical applications, without having to hang the “sword of Damocles” over “two” radio amateurs.

The IARU is expected to inform community members to discuss the French proposal with their governments before the August CEPT-CPG meeting. And France could try to introduce the same proposal to explore 144-146 MHz for aeronautical use in other RTOs.

In the meantime, further discussions by the preparatory group on the 23cm study proposal are expected before the meeting in August. This proposal was made following reports of interference with the Galileo navigation system, but the IARU has stated that it is aware of only "a few cases" of interference with the E6 Galileo signal at 1278.750 MHz. In the meantime, work on this issue will continue in other specialized CEPT forums.

+ Remote control of amateur radio stations - clarified by IARU

National amateur radio organizations are encouraged to make their members aware that CEPT recommendation T/R 61-01 applies to radio operators using their amateur radio call sign with the appropriate host country prefix only when the radio operator is physically located in the country. stay. The above recommendation does not apply to radio remote control. (Recommendation of the IARU Sun City Conference SC11_C4_REC_07)

Remote control is when a radio operator controls his amateur radio through a terminal that is not physically connected to the radio.

For remote control, the following conditions must be met:

Remote control must be authorized by the Communications Administration of the country in which the radio station is located, or the Communications Administration must not object to remote control of the radio station*.

1. Regardless of the location of the operator, the call sign of a radio station controlled remotely must be issued by the Communications Administration of the country in whose territory the radio station is located.

2. It should be noted that IARU Sun City Conference Recommendation SC11_C4_07 calls on national amateur radio organizations to inform their members that CEPT T/R 61-01 applies to radio operators using their amateur radio station call sign with the appropriate country prefix stay, only if the radio operator is physically located in the territory of the host country. The above recommendation does not apply to remote work.

3. Any additional requirements regarding the participation of remotely controlled amateur radio stations in competitions and award programs are subject to regulation by the organizers of these competitions and award programs. (Recommendation of the IARU Conference in Varna VA14_C4_REC_04)

* In a number of countries, including the Russian Federation (see 126-FZ "On Communications"), there is a permissive principle of access to the radio frequency spectrum. In such countries, the absence of objections from the Communications Administration is not enough; its permission is required to use an amateur radio station in remote control mode. The conditions for using an amateur radio station in remote control mode on the territory of the Russian Federation are defined by par. 2 p. 3.1. Rules for the use of radio frequencies

+ How to use the tables Decisions of the SCRF

Introduction

In the Russian Federation, the function of the regulator of distribution and use of the radio frequency spectrum is performed by the State Commission on Radio Frequencies (SCRF). The SCRF is an interdepartmental body, in which representatives of interested ministries and departments, both law enforcement agencies and civilians, take part. The commission is traditionally chaired by the Minister of Telecom and Mass Communications of Russia. The SCRF regulates, among other things, the procedure for the use of radio frequency bands allocated to amateur and amateur satellite services, defining the boundaries of amateur bands, permitted powers and types of radiation, and also setting technical requirements for amateur radio stations.

In accordance with paragraph 4. of Article 22 of the Federal Law of 07.07.2003 No. 126-FZ “On Communications” (hereinafter referred to as the Law on Communications), the use of the radio frequency spectrum in the Russian Federation is carried out in accordance with the principle of a permissive procedure for users to access the radio frequency spectrum. This means that the use of the radio frequency spectrum by amateur radio stations, which is not provided for by regulatory enactments in the field of communications, is prohibited.

Responsibility for violation of the rules for the use of radio frequencies is provided for in Article 13.4 of the Code of Administrative Offenses and provides for a fine with possible confiscation of radio electronic equipment. In addition to this measure, it is possible to cancel the call sign of the offender's amateur radio station.

Radio frequency regulation

The original international instrument is the Radio Regulations of the International Telecommunication Union (ITU RR). Article 5 of the Regulations contains a table of radio frequency allocations for radio services for each of the three ITU regions. The frequency bands allocated to the amateur service are also indicated in this table. The Regulations are regularly reviewed at World Radiocommunication Conferences (WRCs). Conferences are held once every three years, and the next WRC will be held in 2019. The interests of the amateur radio community during the preparation and holding of the WRC are represented by the International Amateur Radio Union (IARU), which is an associate member of the ITU. In turn, CPP, being a member of IARU, also participates in the preparation for the WRC. One of the most important stages of preparation for the WRC is the coordination of the positions of the CRR and the Communications Administration of Russia on WRC issues affecting the interests of the amateur service.

The national (internal Russian) analogue of the ITU RR radio frequency allocation table is the Table of allocation of radio frequency bands between the radio services of the Russian Federation (TRFC), approved by the Decree of the Government of the Russian Federation. Any allocation of frequency bands for their use by RES of the amateur service in the Russian Federation is made on the basis of the corresponding entry in this table.

If one or another radio frequency band is allocated to the amateur service, then the procedure for its use is determined by the relevant decision of the SCRF.

It should be noted that neither the ITU RR table of frequency allocations nor the TRFC specifies the conditions for the use of frequency bands in detail. For example, there are no radio frequency bands allocated by type of radiation, frequency bands for intercontinental DX communications, radio expeditions, and also for use for other purposes that are of interest exclusively to radio amateurs. At the international level, all these issues are regulated by the International Amateur Radio Union (IARU). Each ITU Region has an IARU Regional Organization. In the first Region, which includes the countries of Europe, Africa, the former Soviet Union, there is a regional organization of the first Region (IARU-R1), which publishes a frequency plan - a detailed table of radio frequency distribution. The frequency plan is adjusted once every three years at the IARU-R1 General Conference. The next conference will take place in 2017 in Germany. IARU-R1 recommends that all its members - national amateur radio organizations - when developing national regulations governing the use of radio frequencies allocated to the amateur service, be guided, if possible, by the IARU-R1 frequency plan, and in the part not regulated by national regulations, recommend that radio amateurs use the recommendations IARU-R1.

Why the radio frequency table in the SCRF Decision is not a reference

Since 2015, the radio frequency tables contained in the SCRF Decision contain only information on the basis for the use of a particular radio frequency band (primary or secondary), on the maximum allowable signal bandwidth, as well as on the maximum powers by category. No other requirements for the use of amateur radio stations are made by the SCRF Decision. For most radio frequency bands, the "Modulation Types" column says "All Types".

Is this how it should be understood that it is possible to work with all types of radio communications that do not exceed the required signal bandwidth? Not at all. This only means that government agencies do not care how this radio frequency band will be used by radio amateurs, as long as amateur radio stations using it do not exceed the power and bandwidth of the emitted signal indicated in the table. Failure to comply with these requirements will result in a fine. in accordance with Article 13.4 of the Code of Administrative Offenses (CAO). In more detail about the procedure for using radio frequencies, radio amateurs agree with each other themselves.

In the radio frequency table contained in the SCRF Decision, for example, radio frequency bands for working with DX cannot be indicated. If they were specified, then the supervisory authorities would have to fine radio amateurs for conducting intracontinental radio communications on these frequencies. This is unacceptable for government agencies. Yes, and for radio amateurs - too.

Therefore, the requirements for the use of radio frequency bands by government agencies have the minimum necessary restrictions. All other regulation is carried out at the level of IARU and national amateur radio organizations. Non-compliance with IARU recommendations is subject to public censure.

IARU-R1 frequency plan

The IARU-R1 frequency plan assumes “soft” regulation, which ensures the effective use of the radio frequency bands allocated to the amateur service in different conditions with different “loading” of the bands by stations with one or another type of radiation: when holding mass events (competitions, “days of activity”), changing radio wave propagation conditions, etc.

The IARU-R1 frequency plan assumes a grouping of modulation types according to the maximum bandwidth of the radio signal and the allocation of a specific frequency band for each group. The following values ​​are used as standard values ​​for the bandwidth of the signal spectrum in the HF band: 200 Hz, 500 Hz, 2700 Hz and 6000 Hz. The current radio frequency table in the SCRF Decision fully complies with this principle.

Our website contains tables of radio frequency bands allocated to radio amateurs and recommendations for their use. These recommendations are in line with the current IARU-R1 frequency plan and also take into account the requirements of a number of regulations governing the activities of the amateur service in the Russian Federation.

So, for example, in the radio frequency band 14125 - 14300 kHz, amateur radio stations are allowed to operate on a primary basis by radio communication modes with a frequency band not exceeding 2700 Hz, namely: telegraphy, UBP, AM, image transmission (SSTV). There are no separate frequency bands allocated to AM, but the note to the table states that AM can be used in the bands allocated by the SSB, provided that it does not interfere with users of adjacent radio frequency bands, and it is necessary to limit the use of amplitude modulation.

From the table it follows that amateur radio stations of low power should be grouped around the frequency 14285 kHz, and operators of high power stations should be especially careful near this frequency. Amateur radio stations using digital voice (DV) are encouraged to group around 14130 kHz, stations using SSTV around 14230 kHz.

In this case, it is theoretically possible to give a general call to SSTV at a frequency of 14195 kHz, which is traditionally used to work with large DXpeditions. The violator will not have any responsibility to the state authorities, but this will be a manifestation of extreme disrespect for the radio amateur community. The sanction to the violator in this case will be the condemnation of his actions by the amateur radio community.

It is necessary to understand the difference between the center of activity and the calling frequency. If the radio amateur is sure that no radio station works with this type of radiation, then it is recommended to take the frequency indicated in the table as the center of activity for a general call. At the same time, the calling frequency must remain free: after a call and an answer to it, a pair of radio stations must either end radio communication or continue it on another frequency. The use of calling frequencies is regulated by the Order of the Ministry of Communications of July 26, 2012 No. 184.

Let's take another example. Figure 2 is a fragment of the 7 MHz band table.

It follows from the table that in the frequency band 7050-7060 kHz you can use OBP, and even AM. After all, there is an entry “all types”, and we already know what it means. However, the use of SSB in the bands predominantly dedicated to digital communications can be quite limited. Everyone is well aware that many stations using digital modes of communication, allowing you to work at levels below the noise level, cannot be detected by ear. They can only be seen on a computer monitor using a special computer program. Of course, a short telephone radio contact with a distant station in this section cannot be considered a violation of the recommendations of IARU-R1, but holding "round tables" and "skeds" in these frequency bands, transferring a general call in the case when the frequencies in the upper part of the range, intended specifically for the OBP, are free, is an absolutely unacceptable practice. There are other frequency bands for this purpose.

Note 2 for the 7 MHz band reminds you that the frequency bands given in the table must contain the entire spectrum of frequencies emitted by the radio station. For SSB modulation with the lower sideband adopted for operation in the 7 MHz band, the minimum reading of the transceiver scale indicating the frequency of the suppressed carrier should be 7053 kHz. In this case, the lower limit of the frequency spectrum will be exactly 7050 kHz.

The frequency plan was drawn up on the basis of the decision of the State Committee for Radio Frequencies of July 15, 2010 No. 10-07-01 “On the allocation of radio frequency bands for radio-electronic facilities of the amateur and amateur satellite services” as amended by the decision of October 16, 2015 No. 15-35 on amending decision of the State Committee for Radio Frequencies of July 15, 2010 No. 10-07-01 "On the allocation of radio frequency bands for radio-electronic facilities of the amateur and amateur satellite services" (as amended by decisions of the State Committee for Radio Frequencies of March 10, 2011 No. 11-11-03 of July 22, 2014 No. 14-26-04) taking into account the results of the meeting of the SCRF dated July 4, 2017 (

3. Allocating radio-frequency bands of 50000.0-54000.0 kHz (or part thereof) to the radio-frequency band of the amateur service in the Russian Federation on a secondary basis.

Rationale: Currently, the radio frequency band 50000.0-54000.0 kHz is not allocated to the amateur service in Region 1. Amateur radio stations in Europe use the radio frequency band 50000.0-52000.0 kHz based on a private European table of allocation and use of radio frequencies in the band 8.3 kHz - 3000 GHz (ECA TABLE). It is necessary to initiate amendments to all normative acts regulating the use of radio frequencies - from the RR ITU to the Decision of the SCRF.

Planned terms of use: effective isotropic radiated power of about 100 W, distribution of modulation types in accordance with IARU-R1 recommendations. Use on a secondary basis, subject to obtaining an expert opinion on electromagnetic compatibility with existing and planned RES, permission to use radio frequencies and radio frequency channels and a certificate of registration of RES.
