Just a quick question for the logging gurus:

How often does the EMK change - ie how often is a new "CB/C3-HSN-30- data" command sent to the card?

If I leave a sub card out of the decoder for 24 hours and put it back in, pictures seem to be decoded in about 30 secs. I've logged the insertion, and it appears that, on the few occasions that I have done this, no new EMk (or group key, whatever we care to call it) is received.
