You requested Minimum hour angle (APARM(4)=18hour)
 and Maximum hour angle =0!
That is not good.

CMETHOD should be 'GRID'

I ran UVCON with your infile and your model simulating snapshot observation 
APAR(4)=-0.001, APARM(5) = 0.001 APARM(7) = 100

I have not got the same error message you got.

Instead UVCON complains very reasonably:

UVCON1: ROTFND: CAN'T FIND PROPER AXIS TYPE FOR MAP ROTATION
UVCON1: UNKNOWN CLEAN MAP STOKES TYPE =   0
UVCON1: Destroyed  1 extension files of type AN
UVCON1: Destroyed UV image file: catno=     50 disk= 3
UVCON1: Purports to die of UNNATURAL causes

>UVCON1: ROTFND: CAN'T FIND PROPER AXIS TYPE FOR MAP ROTATION

The list of the coordinate axis at image header of the model image 
does not include (in UVCON) 'solar-we', 'solar-no' which are used at 
your model.

>UVCON1: UNKNOWN CLEAN MAP STOKES TYPE =   0

Stokes axis is required

The attached file includes 
1.the message I got at the end of UVCON run
2.Image header of your model 
3.Image header of the model typically used for UVCON
