Not at all.  I'm sure others have the same question so I'm cc'ing the

In general you use 

  $ svn up

Our svn repository is set up in a pretty much standard way (see the svn
book at subversion.tigris.org)

>From the top it looks like this:

  gnuradio/trunk
          /tags
          /tags/releases/3.0
          /tags/releases/3.0.1
          /tags/releases/3.0.2
          /branches/releases/3.0
          /branches/developers/...

If you check out trunk, then when you update you'll get the latest
stuff in the trunk.  If you want the "stable stuff", checkout
branches/releases/3.0.  Then when you update, you'll get only the
minor bug fixes to the stable 3.0 release.

The trees under tags never change.  They are snapshots.
The trees under trunk and branches have active development in them.

In summary, if you want the latest "stable stuff":

  $ svn co http://gnuradio.org/svn/gnuradio/branches/releases/3.0

Or if you want the latest bleeding edge:

  $ svn co http://gnuradio.org/svn/gnuradio/trunk

Once you've got them checked out, then

  $ svn up

keeps you up to date.

FYI, browsing the repository with trac will show you the layout.
