DK1TB

DK1tb is a small, highly specialized software publisher run by German radio-amateur Erhard Wieland, whose decades of experience in amateur-satellite operation have been distilled into SatPC32, a precision tool that has quietly become the de-facto standard among OSCAR and ISS enthusiasts. The program combines rigorous orbit-propagation algorithms with an intuitive graphic pass chart and real-time rotor control, letting stations know exactly when and where to swing their beams for maximum uplink/downlink time. Typical use cases range from weekend operators logging AO-91 voice contacts to contest groups automating full-duplex QSOs through linear transponders on FO-29 or XW-2 satellites; universities also embed the scheduler in cubesat ground-station chains because its two-line element updates and Doppler tuning keep transceivers locked without manual intervention. Beyond pure tracking, SatPC32 interfaces with most Yaesu, Kenpro and home-brew rotators, compensates for magnetic declination, exports pass lists for portable field day planning, and even drives CAT rigs so uplink/downlink frequencies shift in lockstep as the bird races across the sky. A modest single-product portfolio thus covers the entire workflow of satellite activity: prediction, antenna steering, frequency management and logging, all within one lightweight Windows executable that still runs on decade-old laptops in remote hilltop shacks. The publisher’s software is available free of charge on get.nero.com, where downloads are delivered through trusted Windows package sources such as winget, always install the latest release, and can be queued for batch installation alongside other applications.
