Could try upgrading the Aerial (or adding a Mast Head amplifier to the
existing aerial to obtain better signal quality.
Another option, rather than use a Raspbery Pi, purchase a Core2 Shand
System, there are plenty of low cost HP SFF Desktops available on ebay
that work excellently as a sbe. If configured to shutdown when not in
use, it wont cost you a fortune in power.
