The Vietnamese numbers station on 10255 has settled into something of a routine. First callup is usually right at 1558 UTC. Perhaps someone's clock is a bit off. Transmissions are repeated, but on an irregular schedule. Today, we had three repetitions right together. This seems to be the most common.
The signal is very strong (S9 +10 dB today) on the West Coast, conditions permitting, and weaker in Europe.
This is one of the more compelling "numbers" finds in quite a while. It's daily, on 10255 kHz USB. We really need a speaker of Vietnamese to hear the recordings and figure this out. My own recording has been sent to Monitoring Times and will appear on the magazine's web site at some unknown time in the future.
