2155 Mellow tune playing, JBA in CT but much better on HFUs SDR. Possibly Asian propagation kicking in?
2158 Yup, Asian language being heard. Wrong category for this I guess.
2200 Time pips then off.

Fairly strong signal, nice antennas Chris. Was using 200 ft T2FD.

Almost certainly the Chinese Jamming Service targeting Sound of Hope from Taiwan.

Interesting.  Does the jamming service have commercials?
2159 Female announcer that sounded like commercials in a language I couldn't understand, then time pips, then off.

Probably using a relay transmission of a China National Radio (CNR) feed.

With recent improvements in propagation, I usually have CNR and CRI occupying multiple bands, including multiple frequencies in many of those specific bands. Some legit relays. Some jamming.

China pretends they don't jam anyone by coincidentally transmitting CNR/CRI on the same frequency as the target station.
