I think my problem is solved (or close to it anyway).  I emailed the support 
address of RTKLIB and got a few emails back.

The problem is that the position of the base station has to be given.  I 
thought that if I only wanted a relative position I didn't need to, but it 
appears that I have to.  I just gave a rough estimate of the position of the 
base station and now easily get a FLOAT solution, sometimes a FIX.  Next step 
is to post-process base station log files to hopefully get a better position 
for it, and therefore a better kinematic solution.

Will report back.

Cheers,

Fred
