China National Radio on 13850 kHz

Very little sign of CNR on 13850 kHz from my home location, but some more signal was arriving at the NZ Radio DX League's KiwiSDR in Northland, NZ. No audio decodable though.

Cheers, Chris

Answering my own question, I saw a response from Sun Wei on Twitter (retweeted by Alokesh) indicating 98 degrees which isn't quite north IMNSHO.
