Commented on UVB-76 via Hacker News:
A cool alternative for getting into SDR without purchasing a real device is WebSDR, a webapp to tune and listen to SDR devices that some people have connected online, such as this one (beware, autoplays) [1].
Tune in to 4625 kHZ, and there it usually is, UVB-76, buzzing on all of its glory.
