Gilbert,

I just ran HODO KDVN and got "NO WIND DATA AVAILABLE".  When I ran HODO
74455, however, I got the 12 Z hodograph for Davenport, IA.

It appears that KDVN does not resolve to the station IDN for the
Davenport upper air site.  Here is output from MSL commands:

MSL KDVN
 IDN   ID    STATION NAME         DATA TYPES       ST CO  LAT    LON     ELEV
725349 KDVN  DAVENPORT NEXRAD        F T    D      IA US  41:37N 090:35W 259

So, as far as McIDAS is concerned, KDVN is not the ID for the Davenport
upper air site (actually, as far as McIDAS is concerned, the Davenport
upper air site does not have an ID, it just has an IDN).  You will have
to use the station IDN for Davenport to get the plot.

Technically, the McIDAS station tables are correct, assuming that the
Air Force station database is correct.  Even though the NEXRAD and upper
air sites are located within the same facility, they are distinctly
identified: upper air is WMO number 74455; NEXRAD site is KDVN.  Until
the Air Force changes their database, or until something from the NWS
spcifically defines KDVN to be the upper air site with WMO IDN of 74455,
nothing will change.
