Re: AO-40 question.



Mike,

The attitude information is usually sent in the M-blocks and the transponder
schedule is sent in the N-blocks.  On AO40rcv they can be viewed along with
the K and L blocks under the "mailbox" tab.  The normal block sequence is
such that the M and N blocks are only sent once every 20 blocks.  Sometimes
the command stations will change the block sequence, for example sending all
A-blocks, in which case you might copy a lot of blocks but never get the M
or N block.

The normal sequence is:
AEAK
AEAL
AEAM
AEAN
