S13 – Russian Counting Military Test Station

S13 is the same type of counting station as S14 but given a different ID since it used different callsigns.  It’s most likely a Russian military test station.  The station counts from 0-9 for short periods of time (usually 2 minutes), and uses a live operator.  It would also read occasional announcements for callsign UPT76 and others.
