| Gimpo, South Korea |
Gimpo Siren Jammer (South Korea), transmitting on
1053 kHz (MW), was logged here in Malaysia on 13 and 14 December 2016. Their signal rated a SINPO
of 43423. While their transmission is designed to jam Pyongyang
Broadcasting Station in Haeju (North Korea) -- a super-powered station
rated at 1500 kW -- it was heard mixing with two Asian stations, one
being a Chinese broadcaster at 12.20 UTC and possibly RRI Jayapura
(Papua) at 13.30 UTC. Signal was prominent, although not a major
disturbance, to the Chinese and Indonesian stations when it faded
under. Transmission was observed from 12.20 UTC onward till 14.30 UTC. Additionally, at
19.30 UTC, a Thai station (possibly "Suan Misakawan" -- Monthon Thahaan Bok Thii Sip-Et in Bangkok) and another weaker Asian station (possibly JOAR in Nagoya, Japan) was received; at 22.20 UTC, no jamming was apparent, only an Asian broadcaster.
This is one incredibly powerful
transmitter for it to reach Kuala Lumpur -- a distance of 4,600 km!!!
HERE's an audio file of the Gimpo Siren Jammer.
