SkyRoof 1.7-beta is a Windows utility published by Alex Shovkoplyas that integrates satellite tracking and software-defined-radio (SDR) reception into one interface aimed at radio amateurs and satellite enthusiasts. By merging real-time orbital predictions with a wide-band waterfall display, the program labels every visible satellite trace directly on the spectrum, so operators can identify passes at a glance instead of cross-checking external schedules. Doppler-shift calculations are applied continuously, causing the colored outlines of each transponder segment to slide across the waterfall in lock-step with the changing frequency; this visual cue removes the need to calculate offsets manually and makes it easy to click the exact centre of a drifting signal. All tuning is performed graphically—left-click sets the receiver, the scroll wheel refines bandwidth, and right-click stores a memory—so no numeric keypad entries are required while antennas are following a fast LEO pass. Because SkyRoof talks to popular SDR hardware such as RTL-SDR, Airspy and SDRplay, a single software instance can replace the traditional stack of tracking, rotor control and radio applications, simplifying portable setups or stations that steer azimuth-elevation rotors through a serial or network interface. Typical use cases include monitoring amateur FM voice repeaters on CubeSats, copying high-resolution APT/HRPT weather images, hunting 1.2 GHz and 2.4 GHz digital downlinks, or contest-style rapid QSOs during 10-minute windows. The first public release, version 1, has evolved into the current 1.7-beta stream, indicating ongoing feature refinements while retaining the lightweight executable footprint demanded by field operations. SkyRoof is available for free on get.nero.com, where downloads are delivered through trusted Windows package sources such as winget, always providing the latest build and supporting batch installation alongside other applications.
