Sign on at 2300UTC
2300-2308: 7496kHz
7496 kHz VoTIB til 23.08:30 UT
7495 kHz CHN jammer last longer til 23.10 UT
2308-2328: 7476kHz
7476 kHz VoTIB from 23.08:35 UT S=8 -78dbm in Greece.
7475 kHz CHN jammer from 23.11 UT S=9+5dB in Delhi India.2nd TX on 7486 kHz PARKED at Yangi Yul Dushanbe TJK:
from 23.20 UT start strong empty carrier on air,
parked empty, no modulation til 23.29:35 UT,
7486 kHz stronger than 7476 kHz, in Europe, Greece and Delhi.
2328-2335: 7486kHz
VoTIB px modulation here from 23.29:35 UT S=9+10dB
7485 kHz CHN jammer from 23.32:10 UT - 23.40 UT S=9+5dB in Delhi India.
Another WHITE NOISE scratching jamming observed on
7477.5 and 7500 kHz far away apart distance,
each broad 8 kHz wideband noise string.
But did not disturb the various SDR signals of Voice of Tibet tonight.
Nearby China Tibetan station
7450even kHz PBS Xizang in Chinese from Lhasa Baiding Tibet center
S=8 or -81dBm in Europe,
S=9+5dB or -70dBm in Delhi India.
So the China jammer power against VoTibet
seems also in the 100 kW power range.
2335-2341: 7491kHz
23.35:30 - 23.42:30 UT VoTIB on 7491 kHz.
