China National Radio 1 / PBS via Yushu Tibetan Autonomous Prefecture, Quinghai Province, China was logged on 5 March 2019. Chinese programming, mostly talk format, mixing under Radio Taiwan International was monitored from 14.10 till 14.30 UTC. Reception on the short-wave frequency of 6.075 kHz was SINPO 12431 -- weak signal strength, with strong co-frequency QRM from Radio Taiwan International, yet still audible underneath RTI. HERE is CNR (Yushu) station ID mixing under RTI.
Reception report was mailed to CNR a few days later. I submitted the report using a Goggle English to Mandarin translation, thinking this would secure a QSL. Subsequent to this, I have been told by a fellow DXer that an English language report is sufficient as well. That said, this much prized QSL card from CNR arrived in the mail on 13 June 2018.
