Hi Jim,

The way I left things was for the modified LDM-6.0.11 version of
pqing to be used.  This has the patch that copes with the new line
(NL) character possibly being between the end of one product and
beginning of the next.

OK.

Sounds good.

OK.

No worries.  I think that the single request line is probably sufficient
for you to get all of the NNEXRAD data from atm, so when you uncomment
the request, I would recommend that you uncomment that one.

Did you get a chance to look at my inability to become root on cyclone?
Without this, I can't do the LDM upgrade there.
