This HT was sold at the Dayton Hamvention as a 7 watt HT with a 3800MAH battery,  In trying to program it as a UV5R I could read from the radio but could not install a new image on the radio as I was getting a Unsupported Firmware Version N5R3407BFP3-23XX error.  This radio's drivers are experamental.   I had found out the chip version of the Baofeng programming cable was needing the Prolific 2303  TA drivers which I got from the Prolific web page and these worked ok.  I then discovered you must download the radio as a Baofeng BF-F8HP image and this solved all the problems.  Dave+++++++++++++++++++++++++++++++++++++++++++++ W9DP DAVID PRUITT . - - - - - - . - . . . - - . - . . . - . . . - . . - . . . - - . . - . . . - . . - - David R Pruitt W9DP ( Amateur Radio ) 20 WPM EXTRA Media Services Technician/Computer Network Specialist Vincennes University (Retired) 1506 Franklin Dr  Vincennes, In 47591-6403 812-316-0333 Email: dpruitt@ymail.com
