HI Atsu.

The di-di.di.dah-di comes from the old telegraph lines and it means VE (Verified or Confirmation).

Today's hams use it as QSL or R.

Hello
As you know well, in case of International Morsecode,
the code of 8 dits ........ or di-di-di-di-di-di-di-di
is the code for "correction".

On the other hand, in case of Japanese Morsecode (WABUN),
the code ...-. or di-di-di-dah-di
means "correction".

But we sometimes hear di-di-di-dah-di sent by non-JA stations.
So, I'd like to ask anyone outside JA, how did you know that code and
meaning of that code.
Is there any book or website which shows that code for correction?

Tks in advance
