CHIRP

No programming software will work until there is a computer and working connection between the radio and computer. The programming cable is manufactured with a counterfeit Prolific chip. The Prolific device driver that is auto installed by Windows Vista and above is intentionally incompatible with counterfeit Prolific chips.

The workaround is to download, install and select an older, but compatible, "v3.2.0.0 device driver.":http://www.miklor.com/COM/UV_Drivers.php

Tried FTDI cable. Same results. In the attached zip folder find two files.

Luiton LT-898UV Dump.txt is an HEX dump between the LT-898UV radio and the software provided with the unit (reads channel data from the radio).

CHIRP LUITON LT-898UV Dump.txt is a HEX dumb between the LT-898UV radio and CHIRP software (returns: Failed to download from radio. Radio refused program mode).

Perhaps this information will shed light on the issue. Data obtained using Serial Port Monitor 7.0 by Eltima Software.

Attached file (LT-898UV LINE VIEW.7z) includes HEX dump and additional information.

Have you been able to resolve this on your own since you submitted this?
Have you tried with a recent version since you submitted this?

Closing this due to no more feedback. We can re-open if this is still an issue.
Since you tried a number of cables with different drivers, I'd suspect an electrical problem in the radio (bad connector). Try OEM software, does that work?
