Baofeng UV-5R: Teardown

All About Circuits tears down a Baofeng UV-5R:

"The radios we took apart for this week's teardown are the UV-5R and the UV-5RB, though there appear to be many products by Baoefang with a similar product designation (UV-5R, UV-5RA, UV-5RB, UV-5RC, UV-5R+, UV-5R V2, etc...). While only the UV-5RB will appear in the following article, the interior layout of the two radios is largely identical. I opened two radios because the UV-5RB that I initially tore down had multiple integrated circuits with illegible or completely absent top-side markings."
