V07 is the Spanish language flavor of the Russian 7 operator.

Null format:

661 661 661 000
3-figure transmission ID  
Repeated for 2 minutes

Traffic format:

Preamble Message Outro
845 845 845 1 333 77 92034 90836 61109 ... 12243 000 000
3-figure transmission ID Message count 3- or 4-figure group Group count 5-figure single groups  
Repeated for 2 minutes Repeated twice    

If more than one message is to be sent, the message count in the preamble is greater than "1", and, at the end of each message, instead of "000 000", the transmission ID and the amount of messages are spoken again, repeated for one minute, then the standard message procedure follows for the next message.

Operation habits

V07 operates in regular schedules of three identical transmissions, spaced 20 minutes apart. The schedules usually start at either the full hour or 10 minutes later, but can start any 10-minute interval within an hour. The third transmission does not take place if a null message was transmitted. The frequencies of the subsequent repeats always descend.

The transmission ID and the frequencies used for the three transmissions are related. Putting together the hundreds digits from each frequency used for the transmissions, starting from the first, gives the ID.

History

V07 was first noted as early as 1995, using a male voice. Initially it was targeted at Europe, with schedules on Monday & Friday starting at 20:00, and Tuesday & Thursday starting at 06:00, as of 1999.[1] On 6 February 2001, V07 gained a new female voice; the voice of its sister station E07 also changed at the same time.[2]  The emission mode at the time was AM, with the voice pitched up by one semitone and slightly sped up, which was typical for this agency's AM transmissions until March 2018.

V07's voice used from February 2001 until June 2017

V07 has not operated any European regular schedules since 2007. In 2011, it resurfaced on a new schedule based in the Russian Far East, using USB mode. On 27 March 2012, V07 made two appearances in Europe, at 07:10 and 07:30 respectively, with a different voice and a 30-group message. However, it has not been heard on this slot since.

On 21 June 2017, a Moscow-based test transmission of V07 was made on 10256 kHz[3], a known Russian 7 test frequency, featuring a new voice and a new speed. Following this test, this new voice and speed were introduced on the usual Sunday schedule on 2 July 2017. At the same time, the schedule also received its first major revision, with new frequencies and reorganized time slots.

Since December 2017, V07 transmissions contain an AM crosstalk at +3 kHz within its signal. It has been identified as Radio Vostok Rossii, a commercial broadcaster based in Khabarovsk. The same broadcaster is leaked on V07's tune up carriers as well. This might mean a relocation to Khabarovsk; around 2013, V07's transmitter site was thought to be located on the Kamchatka Peninsula instead.
