I was asked by a local ham about buying a Chinese-designed and -manufactured solid-state amplifier for sale on Ebay. That person didn't tell me which one, but I tend to follow the HF equipment news, and I don't recall seeing any Chinese amplifiers that have received type acceptance certification in the US. Does anybody know if there are any type-accepted HF amplifiers for amateur use that are sourced from China? Without that, it would appear that importing a non-type-accepted RF amplifier is a violation of at least Part 97: §97.315 Certification of external RF power amplifiers. (a) Any external RF power amplifier (see §2.815 of the FCC Rules) manufactured or imported for use at an amateur radio station must be certificated for use in the amateur service in accordance with subpart J of part 2 of the FCC Rules. I tried finding a list of type-accepted HF amplifiers, but I haven't had any luck yet. Does anybody know of a Chinese brand that is street-legal in the US?
