FM radio stations from China tuned in Tutong, Brunei, but Sproadic E propagation

In Brunei's Tutong town, I had already successfully recorded the signal video of Malaysia radio stations from Miri (Bukit Lambir) and Sabah (Bukit Tampalagus), however I also captured 3 China radio stations. 

According to the investigation, these China radio stations that I tuned in Tutong, Brunei were transmitted from Guangdong and Hainan Provinces, but Sporadic E propagation. 

Here are 3 China radio stations that I tuned in Tutong, Brunei on 1st December 2025 around 12pm (UTC+8).

1. Zhanjiang Traffic Music Radio 湛江交通音樂廣播 FM 102.1MHz (1888km from Zhanjiang City , Guangdong Province)

2. 海南民生廣播 Hainan Minsheng Broadcasting FM 101.0MHz (1673km from Ji Jin Ling, Qionghai City, Hainan Province)

3. Voice of South China Sea 南海之聲 FM 102.0MHz (1699km from Qionghai City, Hainan Province)

These China radio stations are zero signal in Tutong, Brunei during normal propagation.
