I saw a post about Nooelect sellings the dvb-t2 dongle and that it
is slightly wider bandwidth than the plain dvb-t dongle.

Looking up DVB-T2 on google, it indicates the bandwidth is 8MHz. There
is a plot on the older DVB-T wiki of a DVB-T signal at about 7.5MHz
bandwidth.

So the question is why do we only see +/- 2MHz? The dump1090 program
would benefit with more bandwidth.
