Are most CCRs Baofeng based? I am looking and they are pretty much the same.
Let's say you want to go into the business of marketing and selling radios. Let's say you have no in-house radio design or manufacturing expertise. So, you go to someone, like Baofeng, who has the expertise in both design and production. You can ask Baofeng to develop a whole new radio for you (expensive) or you can ask for certain modifications to Baofeng's basic design (much less expensive). Those modifications may consist of simply putting your name on Baofeng's standard UV-5R. Either way, the radio has your name on it and you can market it as you see fit.
Most of the cheap, Chinese radios are based on the same "radio on a chip". These are micro-electronic devices that will accept a received RF signal and demodulate it down to audio. Or, they take a series of commands (what frequency, which modulation) and generate a low-level RF signal that is then amplified for transmission. These radios on a chip are not inherently bad, but they do require some external signal processing and they require a microprocessor to run the user interface and tell the radio on a chip what to do. The cheapest of CCRs leave out a lot of external processing (to save money) and the user interface leaves a lot to be desired for native English speakers.
Note that the Yaesu FT-4 and FT-65 are radio-on-a-chip radios. Some say that they use the same chip as the Baofengs. I can say from personal experience that the Yaesus do not produce the same level of spurious emissions that the Baofengs did a few years ago. And, the Yaesu user interface is a little better and better explained in the manual that the Baofengs. My point being that radios on a chip are not all bad.
I think everyone has their one favourate radio
