Known counterpart stations E05, G05, V05

First noted around 1981, ceased in March 1995. Used the old format of E05, which involved 4-figure groups.

Format:

Preamble Message Repeat Outro
186 186 186 1234567890 Ten 1 kHz beeps Count 125 1419 8626 2696 5728 ... Repeat Count 125 1419 8626 2696 5728 ... End
3-figure ID     Amount of 4-figure groups in the message 4-figure single groups   Amount of 4-figure groups in the message 4-figure single groups  
Repeated for 10 minutes   Repeated twice     Repeated twice    

Similar transmission format to E05, with longer breaks between the transmission sections and the beeps, which raised discussion whether this station was actually ran by the same owner as E05.

This station was also heard in standard E05's 5-figure format, as it can be heard on the following recording:
