The UV-B5/UV-B6 does not support 2.5 KHz steps when programming from the
keypad or the OEM software . CHIRP, however, is capable of programming
these radios with this resolution. Unfortunately back in October it looks
like I broke the capability trying to fix something else.

I will see what I can do to restore this capability. In the mean time,
install and use the CHIRP Daily-20131019 build until the issue is resolved.
