Express can do DVB-T

While getting ready for my demonstration next month I tried
using DATV-Express to send DVB-T it worked. I was able to
receive the signal on my £12 Newsky TV Dongle. The CPU
load was much lower than I had expected.

In this mode raw IQ samples are sent across the USB2 link
so for 7 MHz DVB-T that would be 2 x 16 x 8M = approx
256 Mbps.

The picture is of a boxed Express. Version 2 of the board
will be smaller.
