Sorry Kris,
but something is wrong with your report today about Batavia on 6285.
The station on 6285 was not Radio Batavia. It was KR1 Radio, also known as Kennemer Radio Een in Dutch language. And Radio Batavia was on 6275.
I tuned on 6285 only at 1625z, and on 6275 only at 1630. For earlier times, I rely on the reports by ukdxer, JBK and the audiologs by Achim.
All odds are that KR1 was on 6285 from 1413z to 1648z at least,
and that Batavia was on 6275 from 1508z to 1638z at least.
Unhappily, I can't check your details between 1602z and 1615z, when the other reports have a hole (and I was elsewhere on the dial). Maybe you have more on your notepad?
So long, I have to change the subject line to UNID.
