Hi, I just got a new used radio, a Kenwood TH-F6. So I plugged in the radio using a non-Kenwood cable and I went into "radio" and download from radio and selected my radio model and USB0 and I get the message: error no 2 cannot open tty/usb0 error cannot locate tty/USB0. or something similar. I have used this cable and that Ubuntu with Chirp in the past for my other radios, and other than different brands of radios, I have always been able to do this. I know a guy who has done this to this model using the Baofeng cable using a different software in Windows, not the Kenwood software, but one that they purchased. I don't recall the name, but I think it starts with an R. At any rate, I'd sooner buy a Kenwood cable than that other software and keep using Chirp. Hopefully I didn't get it mixed up with the Radioddity cable. I thought I had the right cable with the Radioddity when I sent it off. I don't know if they put the name of the associated radio on the cables, since I'm Blind. But any who, would this be an error for the wrong cable? Thanks. Glenn
