While listening to KGVO out of Missoula, I heard music swelling up underneath, so I nulled the Montana station as best I could and, after a few moments, matched the Vietnamese ballad I was hearing with an online stream for KAZA, known as “Viên Thao Radio,” out of Gilroy, California. By 0316 UTC, the music gave way to a female speaking in Vietnamese. The station stayed mostly audible among the frequency’s competing stations, and occasionally equaled KGVO. At intervals, there were musical stings that sounded like part of a newscast. Then a new song in Vietnamese started at 0336 UTC.
This one’s listed as just 88 watts at night. If that's the true wattage, it was traveling the 760-plus miles to me nicely.
