Back in 2010 when the UVB-76 Temporary Internet Repeater was set up, the political situation was very different from what it is today. The Buzzer looked like an obscure artifact from cold war past and filled the minds with technology mysticism.
Today, the buzzer seems more .. relevant. We are still not exactly sure of its purpose, but for whatever reasons it got upgraded 4 years ago, it seems to keep doing what its meant for.
And so will be its internet representation, so I am in a process of doing some smaller and larger upgrades to the repeater.
As a first in series, the main signal processing software what captures the signal from radio and processes it to a stream, has been upgraded from relatively old WinradHD to its current offspring HDSDR, version 2.70. The reason was mainly a stability, but as a bonus the 24-hour waterfall has now a nice time scale printed on the left side.
