Its the ProdID that I am a little unsure about really.  I have used this
feature to request only certain radars or radar products, but have never
tried with other data.

Thanks for the link, that is a good start.

The above message contained the following:

This can be done via a REQUEST entry in the LDM configuration file
(etc/ldmd.conf).  See

 
http://my.unidata.ucar.edu/content/software/ldm/ldm-6.0.14/basics/ldmd.conf.
html#REQUEST

For details.  Basically, you'll have to work-out the extended regular
expression ("prodIdEre" in the previously-mentioned webpage) for only
the data-products that you want to receive (I'm afraid I don't know the
data identifiers that well).
