E11c was a variant of E11 that ran on separate schedules. It was an alternative null message format, that included an additional, middle 4-digit segment in the ID. First heard on 22 July 2010[1], last heard on 18 April 2013[2].

Format:

757 Oblique 2200 Oblique 00 Out
3-digit ID / 4-digit group /    
Repeated for 3 minutes and 20 seconds  

The 4-figure group was not random. It usually ended in "00", and contained "0", "1" and/or "2".

Prior to 1 May 2012[3], the middle segment was a 3-figure group that consisted of one digit repeated thrice (no groups other than "555", were noted though):

755 Oblique 555 Oblique 00 Out
3-digit ID / ? /    
Repeated for 3 minutes and 20 seconds
