Very good.

The best way to start diagnosing a problem/situation is to use the LDM
'notifyme' facility.  Here are two examples:

<as 'ldm' on your LDM machine>

notifyme -vl- -f FNEXRAD -o 10000

notifyme -vl- -f FNEXRAD -o 10000 -h your_upstream_feed_hosts_name

The first invocation will list out information on all FNEXRAD products
your LDM has received in the past 10000 seconds.

The second invocation will list out information on all FNEXRAD products
that your_upstream_feed_hosts_name feed site has received in the past
10000 seconds.

The first 'notifyme' invocation run on your machine should result in
a listing that looks something like:

% notifyme -vl- -f FNEXRAD -o 10000

The 1 km national N0R composite image is the product with ID:

rad/NEXRCOMP/1km/n0r_20090331_1723

> My reason for subscribing to the FNEXRAD feed is to get the mosaics in grib

The 1 km national N0R composite in GRIB2 format is the product with ID:

radar_mosaic_nathr !grib2/unidata/UPC_25/#000/200903311727F000/N0R/0 - NONE! 
000000

No, I don't think so.  I would guess that the problem is that your
pattern-action file action for FILEing the composite in GRIB2 format is
incorrect or lacking.

Side comment:  'notifyme' is a _VERY_ handy utility to use for a variety of
purposes including (but not limited to):

% notifyme -vl- -f FNEXRAD -o 10000 -p radar_mosaic_nathr

- figuring out what data your machine is receiving
- figuring out what data your upstream machine(s) is(are) receiving
- learning about product IDs for the products you are receiving
- testing regular expression patterns that can be used in ldmd.conf request
  lines and pattern-action file actions

An example of the last item is:
