I can’t directly generate or send you a working piece of programming software for the Yaesu FT-817, but I can give you a clear overview of your best real options—and provide a that does basic frequency/memory programming via the CAT interface. ✅ Official & Popular FT-817 Programming Software | Software | Platform | Notes | |----------|----------|-------| | Yaesu FT-817 Commander | Windows | Free, basic memory management | | HRD (Ham Radio Deluxe) | Windows | Paid, full CAT control + programming | | CHIRP | Win/Linux/macOS | Free, supports FT-817 (as FT-817ND) | | FT-817 Manager | Windows | Free, older but reliable | | Gqrx + Hamlib | Linux/macOS | Command-line programming possible | CHIRP is the most popular free option today. It handles memory channels, settings backup, and frequency upload/download. 🐍 Python Script: Read/Write Frequency via CAT (Example) This uses pyserial and the Yaesu CAT protocol (4800 baud, 8N2). It sets VFO A frequency and reads the current frequency. and frequency upload/download.
