Hi.
Yes Tracy has hit the nail on the head. They were originally sold as TV dongles for DVB, DAB & FM Radio. It was lter discovered that the chipset would tune from as low as 24 Mhz right up to 1.7Ghz on some dongles. They also can tune lower by doing direct sampling and doing a small mod to the hardware.
Their biggest shortfall is no filtering and images are a big issue and they usually land in the spectrum you are intersted in.
I am impressed with the SdrPlay RSP1A it is very good, stable and has switchable filtering which works well.
I have done a good couple of hours with it and the wide band width could make this useful for resolving video if its possible to extract it. Here is a few screenshots and one showing a video waveform on the "scope".
