Baofeng BF-666: Cheap, Fixes

Hans had taken a quick look at the BF-666S (aka the BF-777S aka the BF-888S) and found them to be decent, cheap ($23.50 USD) radios. He sold a couple of them to a fellow ham - after giving him fair warning of the short-comings. As no good dead goes unpunished, this transaction ultimately turned into a bit of detective work and a project to fix the distorted audio. Along with that modification, he also suggests checking the frequency accuracy if you have have access to the appropriate tools.
