Re: [ldm-users] NEXRAD3 rebroadcasts

Thanks Gilbert.    It's always good to know you not just going crazy :)

One thing that had been suggested from Unidata was to just increase the queue 
size to larger so that the rebroadcast data would just get rejected.

I thnk I will give that a try or looks like it will be up to some PQACT magic.

Hi Matt,

I saw that, and it seems like they fixed it late yesterday. Every now and
then, one of their regional LDM servers freaks out. (Note to UNIDATA:
maybe you could make a subtle hint to NWS to update their LDM's
to 6.10.2, whenever that next release comes out?)

No, not really. The problem comes from the fact that the time stamp is
current on the header. The time within the product is not. The real
issue is to fix it at the source. And it looks like they did.
