[NLRS] First tests with DVB-T dongle

[aflowers at frontiernet.net]

My understanding is that these are 8-bit samplers, which if true, limits the dynamic range to a little less than 50 dB.  Hence the need for an RF gain control in many uses.

Probably the biggest problem is overload of the "DC-to-daylight" 
wideband front-end. The E4000 chip has adjustable gain but people are 
still trying to figure out how to set it correctly.... Things are 
getting better as a few people turn up with NDA's and time to write 
code. It is very much a "work in progress."
