1. Introduction

At least since 1997 this simplex network with NCS RAL2 and many outstations is active on several frequencies. The net structure is a Guided Star (no tfc between outstations). Some of the frequencies are shared with CIS Navy networks.
In December 2009 I heard RAL2 calling RLM2 on 4051 kHz immediately after the "P" beacon of Navy HQ Kaliningrad stopped. As this frequency is regularly used by Kaliningrad and RAL2, we may assume RAL2 is a CIS Navy network.
The purpose of RAL2 is not clear however; so far I heard
- radio checks with many stations, normally ending: "ZNN sk sk"
- requests of RAL2 for encrypted voice traffic in MS-5 mode on another frequency
- radio checks on a series of frequencies within a short time, possibly tests of propagation conditions for future use of frequencies.

It seems RAL2 is not a training network nor is it used to send "real messages". RAL2 may be a backup network serving Navy HQs. Due to the short traffic times any attempts to DF the stations failed.
