In 1939 the Russians use the frequency of the Finnish long wave transmitter in Lahti to broadcast in Finnish. During the war a large number of Soviet stations will use the frequency for their domestic broadcasts. The Finnish authorities take countermeasures.

On 31 March 1942 Army station Smolensk starts broadcasting on 610 kHz with 20 kW. The station is swiftly renamed to Soldatensender Siegfried and is moved to Mogilew for security reasons. In Simferopol, the Krim capital, Soldatensender Paul starts broadcasting on longwave on 24 May. Programmes are also produced for the local Krim-Tatar population. On 2 October two Soldatensender start broadcasting: Soldatensender Kaukasus broadcasts from Woroschilowsk on 610 kHz with programmes for the local population. Due to the withdrawal of German troops, the station is silenced three months later. Soldatensender Paula broadcasts from Armawir.
On 31 December the long wave station Golos Naroda (Voice of the People) starts broadcasting from Smolensk.

On 20 July 1943 the Sender Freies Deutschland starts broadcasting on 971 and 610 kHz and via shortwave. On 610 kHz the station interferes with Soldatensender Siegfried from Smolensk. The Germans try in vain to jam the Soviet station with Sender Heinrich in Mogilew.

On 5 October 1944 the Finnish freedom station starts broadcasting on medium wave via Kaliningrad (Königsberg).
