[time-nuts] Can someone post the @@Ea messages from a Motorola Oncore UT just powered up?

Hi Peter,

Thank you for posting this - it is interesting.

An @@Ea message only occurs once every 5 seconds?

It seems odd that it comes up with 08-11-2017 at 12:00:00

My RFTGm-II-Rb doesn't seem to mind it isn't getting the @@En messages...

Thanks,

Alan

The board on it's own comes up in a mode that doesn't send anything until
it's initialized.  The RFTG-m-XO is responsible for setting up the board.
 This is what you see on the RX line after powerup:

Note that this is from WinOncore - the real data doesn't have the (Rx)
prefix and the data is in binary rather than hex.  After this, it repeats
with one @@En message sent for every 12 @@Ea messages
