Though if you want a fair comparison, I
Yes, and from the information I have, H3 and J3 (among others) are both
considered "phone". H3 is full carrier SSB, so there's no lower limit to the
audio frequency allowed, only a 3 kHz upper limit. What's not defined in
Part 97 is what the 3 kHz means - 3 dB down from peak, 6 dB down? And no
slop
Not according to the FCC

Brett, reread part (a) of the FCC rules below. The maximum bandwidth
requirement is applied to each individual emission type (mode). The FCC
acknowledges the right to use voice modes like SSB and even
Brett, reread part (a) of the FCC rules below. The maximum bandwidth

acknowledges the right to use voice modes like SSB and even AM ... it
just says you shouldn't abuse the bandwidth when you do so.

And the FCC regulations are vague, i.e. "...than necessary...", "...good
amateur practice...", "...adjacent frequencies..."
None of these are quantifiable. What constitutes "compliance" is a matter of
personal opinion.
Compare these requirements to those controlling emissions outside of the
