They are certified for all the classes and bands of which the amplifier is capable. A manufacturer cannot "pick and choose" what features they certify ...- Glenn W9IQ
Thats what I said earlier, the data is from the manufacturer, not an fcc testing lab. The FCC just accepted it as correct.
BTW, All 3 amps you listed the submitted data is for F3E modes only. What a deal, a 10 - 80 FM amp!
