I can catch Radio Thailand in Netherlands over 8892 km but I cannot catch Radio Netherlands in Thailand.

Caught on Utwente WebSDR 16 September 2023 19:29:21 UTC 7475 kHz AM from 250 kW curtain array transmitter at Ban Nong Hai, Ban Dung, Udon Thani, Thailand. The station call sign is HSK-9 and is transmitting since 1938.

From analog recording 45.8 dB SNR 70μs.
