what ever happened to the no 10m amp law the usa had? was that removed?
Well, there used to be a Part 97 reg about harmonics of Amateur amps operated above 15 meters.
The FCC Certification listing for most amateur amplifiers are all listed for operation below 25 MHz and the certification stops at 21.450 MHz.
The only HF Amateur amps (that I know of) that are certificated to operate above 15 meters are the Alphas and THP's.
ALL Part 97 HF Amplifiers that can operate above 25 MHz must also pass commercial specifications contained in TIA-603C. (good luck with doing that at current prices)
