Re: T41 Hilbert Filter Design
Hi Dave.? I assume you're interested in FT8 with WSJT on your PC. I know several folks have done data modes with their PC and T41 connected in various ways.? Some modes can be done without modifying

Re: T41 from AI6YM
Yes, the book corresponds to the V66.9 firmware, so you should update the firmware on your radio. You can find the firmware and the instructions here: https://github.com/KI3P/SDTVer066-9/tree/main
