I hit this earlier in my testing, so I must have had things in the right order at some earlier point in the process. 

This : 

           ST_SetSRID(ST_MakePoint(part3::numeric, part4::numeric),4326) as geom, 
           ST_AsText(ST_SetSRID(ST_MakePoint(part3::numeric, part4::numeric),4326)) as geom_text, 
           ST_AsText(ST_Transform(ST_SetSRID(ST_MakePoint(part3::numeric, part4::numeric),4326), 200068)) as geom_city 
          (select rxtime, 
                  split_part(cmd, ',', 3) as part3, 
                  split_part(cmd, ',', 4) as part4 
            where cmd  
             like '>Plot:%') AS first_pass; 

is producing this (which I did hit early on but thought I had the syntax wrong at the time) : 

ERROR:  transform: couldn't project point (44.9677 -93.1268 0): latitude or longitude exceeded limits (-14) 


********** Error ********** 


ERROR: transform: couldn't project point (44.9677 -93.1268 0): latitude or longitude exceeded limits (-14)
SQL state: XX000 

This indicates to me that the transform stuff is there , but that it failed.  I haven't found many references to this error online.  The numbers above are the numbers from the first record in the table.  When I hit this earlier, I thought I might be trying to transform against the TEXT (those numbers) object vs the GEOM object (which I'm supposed to use, right??).  The result of the ST_SetSRID seems to be the correct type of object to pass to ST_Transform based on what I found in my searches.  Maybe I'm not supposed to try the transform in this manner.

It looks like "4326)), 200068)" should be "4326), 200068))"
