There are a few "hardware" Wideband radio receivers out there, depending on budget. Have a look at the site links below - the site does not claim to be a definitive list, and is focused around the pictures of the equipment.

The "big three". Some of the more modern bits of kit cover "DC to Daylight" frequencies.
