Malaysia FM radio stations tuned in Phuket, Thailand?

From Perlis, Malaysia to Phuket, Thailand, the Malaysia radio stations via Langkawi frequencies (Gunung Raya) can be tuned in Satun Province, Thailand, but they can be received up to Thung Wa and Palian (Trang). No signal in Trang and Krabi, however I could tune several Malaysia radio stations at Andaman Sea from Krabi to Phuket by cruise ship.

1. Era FM 90.7MHz

2. Hitz FM 92.4MHz

3. MY FM 100.1MHz

4. Sinar FM 100.9MHz

5. Raaga FM 101.9MHz

RTM Kedah FM 105.7MHz and Langkawi FM 104.8MHz from Gunung Raya transmitter have no signal. 

When I reached Phuket, regardless town or Patong, I cannot receive any Malaysia radio stations via FM frequencies transmission, regardless Gunung Jerai or Gunung Raya.

From Penang to Phuket via cruise ship, Langkawi transmitted Malaysia radio stations still have weak signal at Andaman Sea before reaching Phuket, but interference with Thailand radio stations is detected. I received randomly by tuning Era 90.7, Hitz 92.4 and Raaga 101.9.

Technically, Malaysia radio stations from Gunung Raya (LANGKAWI) has no signal in Trang, Krabi and Phuket Province, Thailand, unless we tune them at the sea via ships.
