NMC3 is FNEXRAD, the floater NEXRAD feed.  It's very small.

Btw, a big change finally occurred today regarding the NMC2 feed - the
NWS is finally using Abilene to transmit the data to motherlode.  Before
it was severely constrained by a T1 line.  Right now that feed is only 3
minutes behind on motherlode - that's pretty good compared to the past.

And, yes, HDS is timely now on motherlode, as is IDS|DDPLUS.  

Is your SSEC feed and OU feed timely?  If so, I'm wondering if there's
some filtering going on.
