Hello,

Having finally got my system to recognise my Freecom USB DVB-T stick, I 
am now having no luck tuning it.  Does anyone have any pointers?

Many, many thanks.

A few file outputs are shown below.

Here is my tuning file:

# Nottingham (Kimberley, Nottinghamshire)
# T freq bw fec_hi fec_lo mod transmission-mode guard-interval hierarchy

Here is the result of scandvb on this file:
