I was following the commit activity as I am learning SVN.  I do not want
to be drummed out of GNURadio for destroying a repository :).

I spent the week down in Chattanooga on a business trip.  Last time I
drove from Boston so I went near VT on I-81.  This time I went by train
so I was over near Danville/Lynchburg area.  I usually take some
vacation along with my trips but this one was a vacation just on the
train.  I did not do as much radio listening or USRP work on this trip
as I planned.

Since the train goes near Newark Airport I was trying to capture some
TIS-B frames.  One advantage of a train over a airplane is I can sit
there in Business Class with my laptop, a USRP box, and a 1090 MHz
Ground Plane without being bothered.  I did not log any TIS-B. :(

After I get the Mode Select stuff checked in, I want to look at the OFDM
code and see if I can figure out some AM IBOC.
