Latest Gempak
FreeBSD, Debian/Ubuntu and CentOS packages are available for the latest release of Gempak, which should have better support for the new radar and satellite files. The packages are available in the web site.
Nbsp-2.0.p3.1
The latest revision of Nbsp supports IDV catalogs out-of-the-box. This allows IDV users to access the data files from a remote Nbsp server. The packages are available in the web site.
Nbsp-2.0.r2
This is the 2nd release of the 2.0 version of the
Noaaport Broadcast System Processor (Nbsp)
This generation of Nbsp contains many improvements and new features
over the Nbsp-1.x versions, too many to list them one by one here.
The most important changes have taken place in the networking module,
which has been revised to support very configurable master-slave setups
to support the i-Noaaport project.
Nbsp can now receive data from various sources, simultaneously,
including Noaaport, Radar Level II data, and/or other Nbsp master servers.
Most, if not all, of the new features are documented in some form in the
README files or the noaaport.net site.
Starting with version 2.0.r2 (this release), nbspd runs as the user
“noaaport”, and therefore the directories where the daemon writes
must be owned by that user:
chown -R noaaport:noaaport /var/noaaport
chown -R noaaport:noaaport /var/log/noaaport
chown -R noaaport:noaaport /var/log/nbsp
chown -R noaaport:noaaport /var/run/nbsp
During a fresh install, the package installer will create the
directories with the appropriate ownership, but not during an upgrade.
If you are uprading from an older version, those commands must be
executed manually.
Upgrading nbsp, even when nbspd is running, is now easier then ever using
the nbspupdate program that is included in the nbspadm package.
See the file UPGRADING for explanations and examples.
Tclssh
The Tclssh package is now included in the Nbsp distribution. This package allows one host to execute tcl commands (and scripts) in a remote host (via ssh).
Nbspgpmap tools
The nbspgpmap package is a bunch of program scripts that use the Tclgempak library to drive several of the Gempak plot programs. The packages for FreeBSD and Debian have been posted in the noaaport.net web site. Something still missing is a good set of examples; I am working on those.
Upgrading Nbsp
Upgrading Nbsp is now easier then ever using the nbspadm package, following these simple steps.
Nbsp G2
The packages and sources for the first release version of Nbsp-2.0 have been posted. Nbsp G2 has many enhancements over the 1.x series, and it has been particularly revised to support the i-Noaaport project.
Nbsp update
Radar level II data can be received only from certain sites, using LDM. Nbsp now has the capability to receive level II data from Ldm, process it and redistribute it. Once Nbsp receices the data from Ldm, it is handled the same way as the data that comes from Noaaport. In particular, it is sent to the filters for further processing, and to the server for redistribution to slaves and clients.
Pre-release packages of Nbsp-2.0 have been posted. Nbsp comes with a set of scripts for producing radar mosaics out of the radar Level III data files. The manual generation of the mosaics is as simple as executing two commands. The first is nbspgdradr, which will produce a , then followed by “nbspradmos ”, where the argument is the output file from the first command. All that can be scheduled for automatic execution by the gpfilter scheduler.
Nbsp has been updated to handle the new dual polarization radar files. Preliminary packages based on this version (2.0) have been released for testing, along with corresponding packages of Gempak based on the latest 5.11.4 revision.
Npstats Update
Npstats has been updated. The default page for the Novra S75 device now displays the graphs for the signal strength and the uncorrectable errors in addtion to the Vber.

Novra Update
It seems that the problems that some people have been experiencing with the newer Novra receivers are due to a firmware bug. I will be testing a new version of the firmware that should correct the problem, and I will post the results here, on Tuesday.
