Did you try 1 stop bit in the COM port settings? I think the K2 manual says 2 stop bits but I have had problems using 2 stop bits that went away when I changed to 1.
The double flash probably means the data is being fragnmented. I wouldn't have thought HRD would assume that a response from the radio would never be broken in the middle, because Simon is a professional programmer and knows what he is doing. I did originally make that assumption in KComm, which is how I know that it happens, but I'm only an amateur. ----- Julian, G4ILO.
