a cipher text smoke bomb
According to the results of querying shortwave-info, double-star Radio is a transmitting station located in Guanyin, Taoyuan, Taiwan. This station will regularly transmit nothing but robot-accented numbers to mainland China at specific times every day. The content is suspected to be to contact the military lurking (spy?) in China. In fact, although this connection is almost impossible to decrypt (without a code table), this method of giving orders now seems to be a stupid and inefficient smoke bomb.

Nice. A somewhat related YT channel that has a few good videos on the history of numbers stations is Lewis from Ringway Manchester. Also really nice drone arial footage of various transmitter sites throughout the UK.
You may also like to listen to some of the episodes from the podcast "Cold War Conversations".
specifically episode 239 about number stations, and episode 277 about a female spy in the USA who was on the receiving end of number transmissions.
Priyom.org is a good place to look up number station schedules on their main page.
More info on New Star from Taiwan
