If you want to have your grant of authorization -- or your marking --
challenged by a competitor or discovered noncompliant by the FCC, all you
need to do is play games with the rules. Conservative observance of
reasonable interpretations of the Rules seems prudent to me.

Hi all!
Thanks for responding. I have tried to get in touch with some folks at FCC
today, if I manage to get through, I will return with their information /
interpretations.
Have a nice weekend!
Best regards

Gary, Amund
We have always chosen the highest "fundamental" frequency as the highest
original frequency generated, normally a crystal or other osc

Gary, Amund
We have always chosen the highest "fundamental" frequency as the highest
original frequency generated, normally a crystal or other oscillator.

So far, I haven't seen anyone quote the actual wording in FCC Part 15. Here
it is, from the table in para. 15.33 (4).
"Highest frequency generated or used in the device or
on which the device operates or tunes (MHz)"
It doesn't appear to concern itself with *how* the signal is

Interesting question and there is a corollary to it. If a crystal
oscillator is stepped up in frequency, with PLL circuitry for example, now
what is the highest frequency.
My current opinion is that for Amund's question it is the crystal
frequency, and to mine, it is the PLL frequ
