That's interesting.
Which FCC or ARRL guideline mentions chirp, or otherwise attempts to
regulate the keying waveform?
I had a look through our Canadian guidelines:
RIC 2 - Standards for the Operation of Radio Stations in the
Amateur Radio Service
I can't find anything about chirp, although there is a clause about
frequency stability, and I suppose that chirp could be defined as
frequency stability over a period of time equivalent to a code
element. But I rather think that it means drift and not chirp.
So - as long as I keep to 6kHz bandwitdh and 1kHz on 30m, then it
looks like I'm allowed to have chirp on my signal.
Now where do I need to solder a small cap on the KX1 to introduce some
nice distinctive chirp on my signal?...
