Hi Chris,
I am taking this info from the LDM 5 Workshop notebook..
Feed Volume
---- ------
DIFAX 19Mb/hour
FSL2 2Mb/hour
HDS 180Mb/hour
IDS|DDPLUS 6Mb/hour
MCIDAS 7Mb/hour
NEXRAD 73MB/hour
NLDN 291K/hour
NMC3(Floater) 3.5Mb/hour
NOGAPS 195Mb/hour
Your mileage may vary, but this should ballpark you..These are "max"
values per hour..
-Jeff
