Please use daip at nrao.edu - I have been on vacation and others may be 
able to help you with problems.

CALIB has a great many inputs and I cannot tell what it is about them or 
about your data that causes CALIB to find no data.  Try using the inputs 
to CALIB in UVPLT, checking particularly CALSOUR and CALCODE and 
DOCALIB.  (Note that DOCAL = 1 may delete some data if there are no 
valid entries for the cal source and note that you have 2 CL tables at 
least and that the highest CL table is used by default.)

If you cannot figure out what is wrong, send me your INPUTS to CALIB and 
UVPLT and I will look at them.
