Are there any specific certifications that radios have to meet to be allowed on the amateur bands? I've been reading a lot about the Wouxun radios that seem to be getting a lot of good feedback. All the Wouxun radios I have found FCC IDs for are certified for Part 90. I'm new to amateur radio but it is my understanding that Part 90 is commercial/business radio and Part 97 covers amateur radio. Anything specific I should look for when shopping for a radio as far as certifications? Are amateur band radios looser as far as requirement and certifications than other radio uses?
