Clubul Competitional Bavarez cu privire la decizia CQ WPX

Ca urmare a deciziei CQ WPX de a limita participarea la concursuri, Chris, DL1MGB a postat o declaratie pe pagina BCC - Bavarian Contest Club prin care anunta decizia de a nu mai participa la sponsorizarea plachetelor WPX.

Mai jos este traducerea, originalul il gasiti aici.

Este greu de găsit cuvintele potrivite pentru situația actuală la care asistăm Ucraina în aceste zile. De multe ori rămânem într-o dispoziție de furie, tristețe și anxietate. 

Mulți dintre noi trăim departe de evenimente. 

Suntem îngrijorați pentru persoanele afectate și ne întristăm împreună cu ei pentru pierderile lor. 

Dincolo de donațiile noastre pentru a ușura o mică parte din suferință, opțiunile noastre de a ajuta sunt limitate. 

Embargourile economice, boicoturile și declarațiile politice care sunt concentrate să lovească guvernele și persoanele responsabile, sunt cu siguranță necesare, dar nu întotdeauna satisfac așteptările.

De curand, CQ Communications, Inc., a decis să limiteze participarea radioamatorilor din Rusia, Belarus și regiunea Donbas la concursurile CQ World Wide DX și WPX pe care le organizeaza. 

Jurnalele din aceste regiuni vor conta doar ca jurnal de verificare (check log), iar contactele cu acestea vor număra zero puncte pentru noi toți.

Clubul de Concurs Bavarez consideră această decizie ca fiind inadecvată și fara utilitate  pentru comunitatea de radioamatori care participa la concursuri.

Printre alte principii nobile, Radioamatorul este de natură apolitică.

Radioamatorismul este un hobby, o activitate de timp liber. 

Radioamatorii a fost întotdeauna mândri că au conectat diferite țări, culturi și oameni cu opinii diferite. 

Radioamatorismul nu a fost niciodată conceput ca aplicare a presiunii politice.

Clubul de Concurs Bavarez consideră că nu este o deturnare a competiției oferirea de plachete ca premiu atunci când sunt exclusi un număr mare de concurenți în același timp. 

A exclude un grup de concurenți doar pentru că sunt conduși de un regim care în prezent este disputat și acuzat puternic nu este ceea ce noi intelegem prin Ham Spirit.

Prin urmare, clubul de concurs bavarez va opri temporar sponsorizarea plăcii pentru viitoarele concursuri CQ World Wide WPX SSB și CW. 

Aceasta include si cele patru plăcuțe pentru categoriile Rookie și Youth. 

Clubul de Concurs Bavarez este, de asemenea, sponsor al altor patru plăcuțe în Concursul CQWW DX și Concursul CQWW RTTY DX. 

Această sponsorizare va fi evaluată ulterior.

Please!

Amateur radio can help rebuild bridges between PEOPLE after the voice of the weapons goes out. 

Wars are horrible and the principles of amateur radio can help us preserve our humanity by being able to see in the other beyond its religious, political, economic or social class choices. 

How many conflicts have existed on the Globe since the beginning; if we had let them prevail, now we would not have had amateur radio. 

There are a lot of other options through which you can get involved on one side or the other, just let amateur radio remain one of the bridges on which peace can come.

Russian AZART R-178 in Ukraine War

Despite the rumors, the Russian are not using Baofeng Two Way radios in Ukraine invasion.

They are using more modern and advanced communication systems, many of them head to head to NATO ones and even better than the Motorola DP4801 used by Ukraine forces.

They are also use MotoTrbo radios like SL-1600 but these are supposed to be captured and used for eavedropping to enemy comms.

The most interesting of all is the AZART system.

AZART R178 is a sixth generation SDR radio able to do almost every waveform.

The tactical radios communicate on frequencies between 27-520MHz at ranges up to 4 kilometres. The MoD states they can also communicate with mobile phones and can receive modulated signals – the turning of digital data into radio signals.

The AZART-P1 (designated R-187) appears to have entered service in 2017, with deliveries continuing intermittently thereafter. It is designed to provide secure, jam-resistant communications for the Russian armed forces.

Due to implementation of a unique algorithm of pseudo-random operational frequency readjustment (FHSS) that becomes impossible for the enemy's EW assets to suppress the radio channels, intercept or input falsified data.

Integrated navigation means provide self-positioning with accuracy of 25 m in latitude/longitude and 40 m in altitude. It is possible to exchange data on positions of subscribers in automatic and manual modes.

The R-187-P1E portable radio station has an inbuilt IR port and USB interface to plug in the PC.

The radio station has:

►an automatic relay mode and
►a time division multiplex mode.

Inbuilt means of packet switching ensure interconnectivity of the Azart system with data transfer networks and civil cellular radio telephone networks. This advantage can be used by Special Forces units when conducting missions in urban areas.

Algorithms integrated into the radio stations' software allow realization of network solutions with properties of self-organization and self-recovery.

It enables establishment of distributed digital networks in the combat area using only two types of radio stations in portable and vehicle-mounted versions.

 The software supports all existing and future communication standards. The radio station is made exclusively on the domestic element base. The basis of the PC Azart P1 is a domestic microprocessor with a frequency of 1GHz, the manufacturing technology corresponds to the 65nm process. The time of continuous operation of the product from one battery is from 6 to 12 hours. Provides data transfer at speeds up to 7.2 kbps. "Azart" allows you to determine the coordinates of GLONASS / GPS with an accuracy of 25 m in latitude and longitude and 40 m in height. Portable radio stations of the 6th generation R-187P1 (previously called "Azart" P1) were successfully used to ensure the security of the XXII Winter Olympic Games and the XI Winter Paralympic Games in Sochi. The decision to use the R-187P1 radio stations was made following the results of a positive experience of use in providing security measures at the Universiade in Kazan. Representatives of the Ministry of Defense of Russia developed and implemented, together with the specialists of NPO Angstrem, a complex scheme for organizing radio communications, which made it possible to organize stable and continuous control of units of the group of troops throughout the territory of the areas of responsibility (taking into account the complexities and features of the terrain) and complete all tasks in full. In the process of organizing radio communications using the R-187P1 during the Olympic Games, the necessary number of radio networks was organized, several relay points were deployed, both ground and air, which made it possible to significantly increase the range of radio communications (ground - up to 18 km, air - up to 70 km). It is worth noting that R-187P1 were also used as repeaters. This is a radio station with programmable radio standards. The radio station operates in a wide range of bands and is capable of providing communication between all existing types of telecommunication technologies - satellite, cellular, Internet, FM radio or digital TV, etc. It alone is able to replace the entire existing fleet of radio stations, while configuring the desired frequency ranges and types of communication is done programmatically. Besides, the device is highly resistant to electronic countermeasures. “I would like to note the Azart radio station of the Angstrem company with a frequency response rate of 20,000 jumps / s. Although not everything worked out in this project, but a bold idea and a non-trivial approach to its solution deserve praise,” said Yuri Sofyannikov, director of the YURION STC. The hopping frequency of 20,000 jumps / sec, such "escape" guarantees resistance to suppression, even if the interference generator hangs overhead under the wing of the UAV or is located several hundred meters away. If there is none, then Azart-P1 is able to operate at fixed frequencies. but a bold idea and a non-trivial approach to its solution are commendable,” said Yuri Sofyannikov, director of the YURION STC. The hopping frequency of 20,000 jumps / sec, such "escape" guarantees resistance to suppression, even if the interference generator hangs overhead under the wing of the UAV or is located several hundred meters away. If there is none, then Azart-P1 is able to operate at fixed frequencies. but a bold idea and a non-trivial approach to its solution are commendable,” said Yuri Sofyannikov, director of the YURION STC. The hopping frequency of 20,000 jumps / sec, such "escape" guarantees resistance to suppression, even if the interference generator hangs overhead under the wing of the UAV or is located several hundred meters away. If there is none, then Azart-P1 is able to operate at fixed frequencies.

Letter from hams of Russia

 Letter: Union of Radio Amateurs of Russia

Dear colleagues!

On behalf of Russian radio amateurs, we appeal to all radio amateurs in the world and their leaders – heads of national organizations.

Since its formation in 1992, the Russian Amateur Radio Union has consistently adhered to the national legislation in the field of communications, the principles of ham spirit, and since joining the IARU in 1994, the IARU Constitution.

Over the past decades, the world has experienced a series of military conflicts involving the United States, NATO and their allies in Yugoslavia, Iraq, Libya, Afghanistan and a number of other countries. And never, no matter which side the Russian state is on in this or that conflict, the Union of Radio Amateurs of Russia did not allow itself any unfriendly steps towards radio amateurs and amateur radio organizations of the countries participating in the conflicts.

And now we expect from radio amateurs and national amateur radio organizations the same responsible approach that they themselves have taken during these three decades.

Each of us off the air can give his own assessment of what is currently happening in Ukraine, but today we can and must demonstrate to the public that radio amateurs are a community of people who treat each other with respect, regardless of political beliefs, religion and nationality. The amateur radio service promotes mutual communication and friendship between people, IARU is out of politics. This is what the IARU leadership emphasizes in their appeal dated February 28, 2022.

World history, including the history of amateur radio, knows many examples when unfriendly steps, various boycotts only aggravated conflicts. At the same time, it was radio amateurs who many times came to the aid of victims of disasters and emergencies, providing communication, and thereby saving people’s lives.

In connection with the events in Ukraine, the Russian Amateur Radio Union invites radio amateurs and amateur radio organizations – members of the IARU to remain true to amateur radio traditions: to refrain from rash emotional acts using Amateur Radio in any of its manifestations for this, not to lose contact with each other, to show wisdom and mutual respect and thereby contribute to the speedy settlement of the situation.

Union of Radio Amateurs of Russia.
