Yes, 47CFR97.307 (Mike quoted below) is the regulation that is usually
referenced by an ARRL Official Observer (OO) reporting chirp. 

Of course, the regulations do NOT provide specific parameters nor have I
heard of the US Federal Communications Commission (FCC) ever issuing a
citation for clicks or chirp as long as the emissions remained within the
Amateur band. It all comes down to a matter of personal opinion about what
constitutes good Amateur or engineering practice.

I got an OO card some years back that said he could definitely hear "...just
detectable chirp" on my signal. In the QSO he cited I was chatting with
another station about the vintage rig I was testing and how they *all*
chirped a bit. It was inherent in the design. Had that OO been 'reading the
mail' he'd have realized he need not waste his time advising me he could
hear what we were talking about <G>. 

I'm not denigrating the OO service. The technically-competent OO's provide a
real service to the Amateur community to alert Hams when their rigs are
mis-behaving in some manner that is observable on the air. 

On the other hand, I've known a number of new hams to be really upset when
they got an OO card, thinking they had been "cited" for some infraction of
the rules, especially when the OO quotes an FCC regulation like the one
below as if the operator had violated it when, in fact, it was all a matter
of opinion. And, as the level of technical knowledge required to get an
Amateur license continues to drop coupled with more and more Hams focusing
on specific modes and on-air activities, we'll probably see a greater and
greater range of "opinion" in the future. 

One of the very important concessions us Hams have managed to maintain over
the years is a minimum of rules that restrict us. In the USA at least, the
FCC is very lenient, allowing and encouraging Hams to tinker and experiment
and just have fun with a variety of equipment and technologies. What we get
is a freedom no other radio service enjoys, but it requires us Hams to be
very tolerant of each other and what we think is "good practice" considering
what we are doing at the time. 

There's no rule that says that every rig has to sound as good as an Elecraft
rig. Besides, as I observed earlier, I can read a very weak slightly chirpy
signal much more easily than one that doesn't chirp, therefore a little
chirp is essential to meet the standards of good Amateur or Engineering
practice in that case, Hi!

97.307(a) No amateur station transmission shall occupy more bandwidth than
necessary for the information rate and emission type being transmitted, in
accordance with good amateur practice. 

(b) Emissions resulting from modulation must be confined to the band or
segment available to the control operator. Emissions outside the necessary
bandwidth must not cause splatter or keyclick interference to operations on
adjacent frequencies. 

(c) All spurious emissions from a station transmitter must be reduced to the
greatest extent practicable. If any spurious emission, including chassis or
power line radiation, causes harmful interference to the reception of
another radio station, the licensee of the interfering amateur station is
required to take steps to eliminate the interference, in accordance with
good engineering practice.

And it continues on with regard to specific standards and measurements of
spurious emissions.
