Jammer, North Korean, jamming The Voice of The People, July 24, 2011, 1545 UTC, 4450 and 8900 kHz

This is a Jammer (4450 kHz) and second harmonic (8900 kHz) , probably from North Korea, covering the Korean language broadcast of the Voice of the People, July 24, 2011, at 1545 UTC. VOTP is on 4450 kHz and the jammer fundamental is also on 4450 kHz. But the second harmonic of the jammer on 8900 kHz is clearly heard also.

Recorded and received usinf a remote Perseus receiver located in Japan. The signal was usable at my location in the Mojave Desert of California, but the 2nd harmonic was very low level. So I selected a Japanese remote to get a good copy on the harmonic.

4450 kHz is Voice of National Salvation operated by National Democratic Front of South Korea (NDFSK), a notional guerilla group run by North Korean. So the jamming is from South Korea...

@mosesofmason3 Every online source I can find (including the Aoki list, EiBi List, NASWA list) indicates that on the day and time this recording was made (and still to this day) 4450 kHz was used by the Voice of the People, transmitting from there facility Kyonggi-do, South Korea. Just this morning I heard Voice of the People on this frequency, with their ID and announcement. Naturally, multiple stations sometimes use different frequencies, but this is a video of North Korean jamming, not South

@mosesofmason3 If your source of this information is ClandestineRadio (dot) com you might look at the age of their information. NDFSK out of PyongYang used the 4450 frequency about 7 years ago, but today it is Voice of the People on that freq.

This is very interesting, what kind of radio do you have? thanks for sharing this

@Staplesz This particular radio is a Microtelecom Perseus SDR. My videos are mostly made using one of four SDRs, this Perseus (or connected remote Perseus units), The RFSpace SDR-IQ, RFSpace SDR-14, or the WinRadio Excalibur G31DDC SDR.

I just picked this up this morning 1/20/12 at 4450 khz being jammed by a continuous humming airplane sound that went on all night and into the morning.
