[A-DX] [BDXC-UK] North Korea 'aggressively' jamming BBC's new Korean-language service

[Wolfgang Bueschel]

Re "aggressively targeted,

--- NOT YET -- wait til the KRE Jamming secret service
will set a real powerful jammer on that 5810 kHz channel.


9940.003 kHz S=9+5dB from Tamsui Taipei TWN relay, 300 kW,
no whistle tone - probably North Korean jammer -
minus 1376 Hertz heterodyne whistle tone interference
NOT  ON  AIR  today
at 1748 UT on Sept 27.


5810even fq kHz, from RRTM Tashkent Uzbekistan relay site,
S=9+25dB also heard in remote SDR units at Hiroshima and Tokyo Japan.

Very low tiny army reserve jammer likely on limited local at Pyongyang area,
underneath at 17.55 UT Sept 27,
not to compare to powerful S=9+10dB strength KRE jammer
on 5830, 5920, 5930, 5995, 6003, 6015, 6135, 6250, 6350, 6520, 6600 kHz.

and also some very strong KRE jammer spurs and fundamentals
visible on the Perseus screen, on
5708 to 5801 kHz,
5864 to 5882 kHz,
5930 to 5940 ditter
5830 kHz S=9+15dB
5995 S=9+10dB etc. etc.
