Baofeng BF-888S and Aussie UHF CB

From Wikistix

WARNING: Even if correctly programmed with the allowed UHF CB channels, these radios are not legal in Australia, ie. they are not approved for use. See Type Approved for lists of radios and their approval status. You have been warned.

Bought a couple of these cheap 'Baofeng/Pofung BF-888S' (aka HST H-777) radios from eBay. What arrived was branded "SYNiC 888S", with a reported frequency range from 400 MHz to 470 MHz, which doesn't include the Australian UHF Citizen Band (CB) of 476.4125 to 477.4125 MHz inclusive. Both are likely based on the same 'BEKEN BK4810' radio chip, which may have a frequency range as large as 134 - 490 MHz if the BK4813 specifications match the BK4810. Trying to program them with CHIRP, it rejected any frequencies outside the allowed range. YouTube videos recommended enabling developer mode and editing the channels via the advanced mode browser, which allows almost arbitrary values, however, a quick patch to CHIRP allowed expanding the allowed frequency range to include UHF CB.

The below channel lists can also be used on their other radios, including UV-5R, UV-5Rv2+, UV-5RA, UV-5RE, UV-5R+.
