1. Radio Eritrea on 7185 MHz Radio Eritrea appeared on 7185 kHz together with white noise from Ethiopia. The German PTT filed 2 official complaints. 7146.5 and 7175 kHz were still in use, too.

2. Russian Navy Sevastopol on 14180 kHz – good news The Russian Navy (ident “RDL”) was transmitting on 14180 kHz on F1B with 50 Bd and 200 Hz shift for several days. Location: Sevastopol – Crimea — The German PTT filed an official complaint. On Oct. 31st the transmissions were found the last time. Many thanks to the German PTT in Konstanz.

3. Russian Radar Contayner on 7 and 14 MHz – no change The Russian radar Contayner was again active with long lasting transmissions on 7 and 14 MHz, often with many spurious emissions. The same radar disturbed the WAG-Contest on 7178 kHz on Oct. 15th . 4. Russian FSK4 on 80 m (shared band!)

We observed a Russian FSK4 system on 3530 kHz on Oct. 13th at 2009 UTC. Location: Syktyvkar. Parameters: 100 Bd and 1500 Hz shift. This system is not common on our bands. Observe: 80 m is a shared band! Screenshot: DK2OM with Wavecom W-Code….
