International Radio Serbia, transmitting from Bijeljina, was logged on 31 May 2014. Serbian language and folk music was observed from 19.32 to 20.00 UTC. Reception on 6.100 kHz at 19.32 UTC was (SINPO) 24322 -- weak, atmospheric noise and fading, but audible speech and music. At 19.45 till 19.55 UTC co-channel interference from Voice of Korea caused severe QRM, which degraded reception further to 22322. When Voice of Korea signed-on at 19.58 UTC, signal of Radio Serbia International could not be received.
