Sorry you have such a problem with basic literacy.

I stand by exactly what I said.

An unmodified manufactured amp that is not "certificated" is not legal
for use in the US Amateur Service, regardless of where it was
manufactured. A constructed or modified amp is potentially legal if
operated within the output power rules.

Did you read something else?


There might be some wiggle room here... the relevant regulation:
97.315(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. No amplifier capable of operation below 144
MHz may be constructed or modified by a non-amateur service licensee
without a grant of certification from the FCC.


OK.. parse it out..

"manufactured or imported for use at an amateur radio station" must

This means that it only applies for amplifiers intended for use at an
amateur station. If one manufactured an amplifier for use, say, in a RF
induction heating system, one wouldn't need to be certificated for that
use. (one might need certification for other reasons...) See, e.g.,
http://www.manitousys.com/media/pb3_manual.pdf.. They have a photo of
the back panel, and I don't see a FCC registration number there. (nor
does manitou show up in the FCC databases for authorization or grantee)

But, it's pretty clear that if that amp has a switch on the front
labeled, for instance, "80m band", then it has to be certificated for
use in amateur service.

(and, it's mighty tough to get a "certification for amateur service" if
it can do other things.



If one went to Amplifier Research (http://www.amplifiers.com/, for
instance, one could buy a general purpose RF amplifier. That wouldn't be
"manufactured or imported for use at an amateur station" so it wouldn't
need to be "certificated foruse in the amateur service".
