E06a is a variant of E06 with two messages, sent accordingly to the standard multiple message procedure, but the first of the messages has rigid format - the first group is always 11111, and the second starts with 000.
E06a rarely makes appearances, but the transmissions are still repeated an hour later, and 24 hours later at the same times and on the same frequencies as the previous day.
