Many interesting results! I didn't know that China has stations broadcasting at more than 1 million watts. I guess those super high power stations are needed in the Chinese countryside. And to send propaganda to Taiwan, since someone mentioned the signal is directional.
All the U.S. is sending to Cuba is one 100,000 watt station the Cubans routinely overpower across the island. As David tells us, there's no need to jam Radio Marti. Cuba is a big island and they have several powerful AM stations on 1180, just as they do on 1190 and 1170. It's not jamming, it's just routine. But it has the same effect, that Radio Marti is almost unlistenable in Cuba. And we're not investing in any million watt directional Radio Marti transmitters.
I was also unaware that some Asian nations still have stations on Long Wave. Geez, if the AM band is declining in usage in North America, how many people are tuning in LW stations in Asia? Although again, if you are in the remote countryside, maybe there are no FM or AM stations near you. You may need LW or a super powered AM signal to have anything to listen to.
I have from time to time watched Filipino TV. My cable system has one Filipino station unscrambled. It is interesting how they switch from Tagalog to English so frequently, sometimes in the same commercial. Sometimes in the same sentence!
It's fairly easy to tell Cantonese from Mandarin. Mandarin has no words ending in a T or D sound. Only vowels, R and N. So if you hear Chinese but with other ending sounds, it's likely Cantonese.
