F6CTE

F6CTE is a small, technically focused software publisher operated by French radio amateur Patrick Lindecker, whose callsign F6CTE lends the label its name. The company devotes itself exclusively to advancing digital amateur-radio communication, delivering a single, tightly engineered application that turns any Windows computer into a multimode software-defined transceiver. MultiPSK decodes and encodes dozens of digital modes—PSK, RTTY, CW, Hell, MFSK, Olivia, Domino, Throb, MT63, SSTV, FAX, NAVTEX, ACARS, AIS, DSC, EPIRB, SITOR, SELCALL, Packet, Pactor, WSJT, Q65 and more—making it a reference tool for short-wave listeners, DXers, satellite trackers, emergency communicators and hams experimenting with weak-signal protocols. A built-in spectral analyzer, automatic frequency control, logging functions and rig control via Hamlib or Omni-Rig allow seamless integration with physical radios, while audio routing through virtual cables supports pure software operation. Because every mode is implemented in native code, latency remains minimal and decoding sensitivity high, qualities valued in contests, traffic nets and scientific propagation studies. The publisher maintains a detailed online handbook, updates the mode library in step with band-plan changes and keeps licensing strictly free for non-commercial use, encouraging classroom and club adoption. The entire F6CTE catalogue—at present the multimode digital transceiver MultiPSK—is offered for free on get.nero.com, where downloads are delivered through trusted Windows package sources such as winget, always install the newest release and can be queued for batch installation alongside other applications.
