Baofeng UV-B5 / UV-B6 PC programming software 1.09
===================================================

WHAT THIS IS
------------
BaoFeng's factory Windows programming software for the UV-B5 (and the
UV-B6), version 1.09, Chinese/English. The installer is a self-extracting
setup (UV-B5_520MSetup_v1.09.exe) whose product name is "UV-B5"; the program
window is titled "UV-B5 - PC Software" and carries the version string
"UV-B5 1.09". The program files inside are dated 2012-09-22. Its model table
lists six frequency-range variants (136-174/400-470, 144-148/430-450,
144-146/430-440, 136-174/245-246, 136-174/400-520 and 144-146/430-432 MHz),
so one program serves the regional versions of the radio.

It reads and writes memory channels and settings. It does not update
firmware.

This is the only version of the factory UV-B5 software that was found. BaoFeng
never published it on a site that survives: it survives as a community copy on
Miklor, the long-running BaoFeng reference site, which labels it "Baofeng
UV-B5 / B6 v1.09 (Chin/English)". No earlier or later version was found.

APPLIES TO
----------
- BaoFeng UV-B5 and UV-B6 handhelds (Miklor lists both, 136-174 / 400-480
  MHz).

Must NOT be used on: other BaoFeng models (UV-5R family, BF-F8HP, UV-82),
which use different software and memory layouts. The program itself warns
"Model type is wrong.Overwrite?" when the file and radio do not match.

BEFORE STARTING
---------------
- A Windows PC. The program is 32-bit; supported Windows versions were not
  stated.
- A USB programming cable with the Kenwood-style two-pin (K1) plug, the same
  type as the UV-5R/BF-F8HP cable, and its USB driver (FTDI, Prolific PL2303
  or CH340 depending on the chip in the cable; see the Prolific driver entry
  in this archive for the counterfeit-chip problem).
- A charged battery.

INSTALLATION
------------
 1. Run UV-B5_520MSetup_v1.09.exe. It installs to Program Files\UV-B5 by
    default and creates an uninstaller.
 2. Install the programming cable's driver and note its COM port (Device
    Manager > Ports).
 3. Turn the radio off, push the cable firmly into the speaker/mic jack, turn
    the radio on.
 4. Start the program, select the COM port, and read the radio first. Save
    the read data to a file as the radio's original backup before editing.
 5. Edit, then write back to the radio. Do not disconnect during a write.

The program's screens were not seen; the menu names could not be confirmed.

VERIFYING
---------
Read the radio again after writing and compare with the edited file; check a
few channels on the radio.

IF SOMETHING GOES WRONG
-----------------------
- Miklor's warning, which applies to this software: "There is a Test Mode
  within the factory software. It allows adjusting the power level of the
  handheld." Changing Test Mode values alters the radio's factory alignment.
  Leave them alone, and save a read of the radio before touching anything.
- No communication: wrong COM port, cable not fully seated (a common problem
  with K1 plugs), radio off, or a missing/incorrect cable driver.
- CHIRP (also in this archive) supports the UV-B5 through its "uvb5" driver,
  which CHIRP marks experimental because it also exposes the Test Mode
  settings.

DOWNGRADING
-----------
Not applicable. No firmware update for the UV-B5 was ever published (none on
BaoFeng's or BTECH's download pages, none on Miklor), and no other version
of this software was found.
