I am getting an error "Failed to read header (0)" when trying to use CHIRP to read my FT-8900. I am using a USB cable acquired from www.409shop.com and a Prolific 2.0.2.1 USB driver on an XP home system. The cable is being properly detected by XP. The same XP home system is being successfully used to read my BaoFeng UV-5R and my Yaesu VX-7R, both using different USB cables but the same driver. For what ever it may be worth, the RT Systems software (ADMS 2H) is also failing to read the FT-8900, showing a "clone error" on the FT-8900 display when I use the USB cable from www.409shop.com. However, I am able to read the FT-8900 using a USB to Serial adapter and the serial cable that RT systems supplied many years ago. It would appear that my problem is the USB cable from www.409shop.com ... but I would appreciate a second or third opinion. Thanks in advance.. -- John 73's de K9RSQ
