Yaesu FT-1900 invalid header
Chirp communicates with FT1802M but corrupts radio.
will not communicate with FT-2900/1900R.
Therefore cable is OK.

I had this issue a few times, best thing I can say is the cable driver needs refreshed. try unplugging cable then uninstall / reinstall the driver for the cable.
Also watch your timming while accessing the commands for the radio>computer. You have to hit the V/M after selecting
If these two dont work than I would suggest reinstalling Chirp or getting the software from the G4HFQ Site. 73.
