R-187-P1   Azart
Military HF/VHF/UHF software defined radio - wanted item

R-187-P1 (Russian: Р-187-П1), 1 also known as AZART-P1, is a military-grade HF/VHF/UHF two-way handheld radio, developed around 2012 by the Russian MoD in cooperation with NGO Angstrem 2 (Ангстрем) in Moscow (Russia). It is the successor to the R-168 Akveduct (Акведук) family (2000-2016). Part of the AZART (АЗАРТ) family of devices, this sixth-generation digital tactical Software Defined Radio (SDR) can be used from 27 to 520 MHz with full encryption on VHF and UHF. It offers a selection of analogue and digital waveforms, including AM, FM, and SSB.

The radio supports the digital TETRA standard, which has two modes of operation: TMO and DMO. In TMO it allows digitally encrypted com­mu­nication, but only when a suitable repeater (base station) is present in its vicinity. In DMO, direct digital communication is possible between mobile stations, but without encryption. Instead it offers audio masking, which is probably a time and frequency domain (F/T) voice scrambler.

As a powerful counter-countermeasure against eaves­dropping and jamming, the radio offers a sophisticated Frequency Hopping (FH) mode.

With FH enabled, the radio can make up to 20,000 frequency jumps per second. FH also reduces the chance of being located by means of Radio Direction Finding (RDF). To allow FH at this rate, the radio used GPS and Glonass for synchronisation. 3 It is backwards compatible with previous generation Akveduct devices, which offer a frequency hopping rate of 100 jumps per second.

The R-187-P1 (AZART) was first used by public safety organisations in 2014, during the XXII Olympic Winter Games in Sochi (Russia). The Russian Armed Forces started using it in 2015. The device was also used during the Russian invasion of Ukraine, but in limited quantities, which led to public speculation about its quality. Although the device was completely designed in Russia, it was rumoured that it was manufactured in China and that the build quality was sub-standard. This has since been refuted. During the Russian invasion of Ukraine [9], some R-187-P1 radios were captured and analysed by Ukranian Forces, who managed to put them to their own use.

The export version of the device — which probably offers less secure encryption — is known as R-187-P1E. A mobile version of the radio with a wider frequency range and a higher output power, is known as R-187-VE. The AZART R-187-P1 is expected to be succeeded during the course of 2023 by AZART-2, which offers enhanced performance and less power consumption.

PLEASE HELP — At present we have no further information about the Russian R-187-P1 (AZART) radio. Any further information or documentation would be greatly appreciated. We are also looking for a working AZART R-187-P1 radio for a reasonable price. If you think you can help, please contact us.
  1. The Russian word АЗАРТ (AZART) means Excitement or Passion.
  2. Also written as Angstrom or Angström.
  3. If the GPS or Glonass channel is jammed, the radio looses its high-speed Frequency Hopping capability.

The radio supports the digital TETRA standard, as defined by the European Telecommunications Standards Institute (ETSI). TETRA has two modes of operation: Trunked Mode Operation (TMO) and Direct Mode Operation (DMO). In TMO it allows digitally encrypted communication, but only when a suitable repeater (base station, or network mast) is present in its vicinity. In DMO, direct digital communication is possible between mobile stations, but no encryption is available. Instead is offers audio masking, which is probably a time and frequency domain voice scrambler.

Counter-countermeasures (CCM)
In the military scene, mobile radio sets commonly provide Frequency Hopping (FH) as a counter-counter­measure (CCM) against eavesdropping, jamming and locating by means of Radio Direction Finding (RDF). in the case of the R-187-P1, the frequency can be altered up to 20,000 times per second, in a pseudo-random pattern determined by a secret proprietary algorithm. To achieve this high hopping rate, the radio relies on GPS or GLONASS for synchronisation. When the GPS or GLONASS signal is jammed, the high hopping rate cannot be used.

The device is backwards compatible with previous generation Akveduct (Акведуцт) devices, which offer a frequency hopping rate of 100 jumps per second.

Channel frequencies and modes of operation can be programmed directly on the radio using the built-in keypad and the colour LCD display. Alternatively, all features can be programmed via a separately available data cable and a Windows software application, although this application is reported to be rather buggy. By default, the output power of the radio is only half of what is advertised. To get full power, the push-to-talk (ptt) button must be pressed twice in quick succession at the start of a transmission.

Password protected radios can be unlocked with the master password 52867061.
