Software Defined Radio (SDR) has finally reached a much broader mass of people, who wanted to play with RF technology, but didn’t find the time or resources to learn all necessary skills, to build a hardware based radio. Thanks to the work of the GNU-Radioand OsmoCom developer crowd, this barrier is finally gone and everyone can, more or less, directly access, what the antennareceives.
The last Mission-Log about a GNU-Radio based NFM SDR receiver pulled in a lot of people, looking for examples, to better understand GRC and to improve their own SDR projects. The real beauty about it is this: Unlike hardware receivers, which can’t simply be replicated and shared, we only have to come up with good software receivers/transceivers once and then may just share them amongst each other, without any limitation.
However, the antenna itself, is still hardware and will most likely never be replaceable by software. On ##rtlsdr people often ask about antennas, because they are clearly not satisfied (and who could blame them) with the performance of the original L/4 DVB-T stub.
