Retransmits can be due to an NWS office not getting the product correctly.
Awips can request it be resent. You will see that a lot during ice storms etc.

Follow-up: They switched to the BNCF at 14:15Z this morning. I i'm not seeing
missing satellite images, but I am seeing a huge number of re-transmits and
duplicates that the LDM is rejecting at AllisonHouse and COD. A contact I have
at NCF emailed me to check on it, and I have given him log samples so he can
see what's going on.

Good day everyone,
I am going to try to kill two birds with one stone here.
1. The GOES-16 missing tiles issue has been resolved when SBN/NOAAport is
sending their uplink via the ANCF and primary uplink. This problem was due to
multiple
issues, but they have gotten them taken care of on the NESDIS side of things.
They had a nagging problem with channel 10, but that has been resolved (they
had an issue at 14:10 with
a missing tile this morning, but NOAAport was down for 5 minutes while they
made expected changes to the SBN this morning, and all channels had a glitch at
that time).
2. Additionally, the out-of-sequence packet issue when they are on the ANCF has
been resolved, and was determined to be an NCF issue.
But…
When they are on the BNCF, and transmitting from their alternate uplink site,
they still experience out-of-sequence packets, numerous missing products
that have to be resent (we see a LOT of duplicate products here at COD when
they are on the BNCF), missing satellite tiles…and even missing satellite
images.
NCF is aware of the situation. Last week they switched to the BNCF for 3 hours,
and the problems were still there, so they switched back to the primary. They
are working on it.
