They are not necessary on at these times, but rather these are the times they are permitted to operate on a given frequency. Refers to the number of times a station has been logged, a combination of how often it is on and how well it propagates. These transmissions are emergency backups to relay AM radio programming and are intended for NHK AM radio stations around Japan. Since they have no real audience on these back-up relay transmissions, they're all tests only, and are irregular, though almost daily. On most nights Radio One does not sign off.
IDs can be hard to come by.
Of course, the Japanese programming and USB signal probably mean that you have them, but check the other frequencies to see if other relays are carrying Radio One. The NHK relays are good verifiers and reply to reports quickly. This guide would not be possible without Sonny Ashimori. Sonny has provided the key insights and information on these relays. I m simply a listener to these stations and a compiler of Sonny s and other Cumbre information.
