Why not?
- IntelMiner 9y agoSpeculation: A digital TV signal is a lot more repeatable than an analog one. A digital signal doesn't have the "TV static" effect of an analog signal that may introduce different entropy between two devices pulling the same signal in different locations
- jamesmcnalley 9y agoI'm not sure I agree that a digital TV signal has more repetition than analog. It is possible, but worth investigating. That said, although the DVB-T dongles were intended for digital TV use, the typical demodulators (such as http://www.amateur-radio-wiki.net/index.php?title=RTL2832 http://www.amateur-radio-wiki.net/index.php?title=RTL2832) have an extremely wide frequency range and can be repurposed all over that range. Absolutely use extreme caution when adopting a new source of entropy.
