Audibility
Perhaps put
 * In a professional communications receiver designed for CTCSS, a high-pass audio filter is supposed to block CTCSS tones (below 300 Hz) so they are not heard in the speaker.

into a new sub sub section called Audibility. Because lots of us indeed hear them. Jidanni 00:15, 2 October 2007 (UTC)

PMR 446
I just reverted an unreferenced edit that asserted that PMR 446 had a standardized set of identifiers for the squelch tones. While quite a few radios do use a sequential series of numbers for the squelch tones supported by that radio, I've not seen anything that indicates that there is any standard identifiers than the Motorola PL codes. I'd be happy to help add that to the table if it can be referenced as something more than one manufacturer's set of numbers.

Also the person tried being helpful by evening out the three tables, but they are three separate tables on purpose, Each table contains codes from a different harmonic sequence. Caerwine Caer’s whines 16:52, 14 April 2008 (UTC)


 * I came to this article looking for the 1-38 non-standardized numerical squelch codes, and found what i needed in citation #2. Actually all the information is given on which codes to exclude from the numerical line-up in the article. You are forced then to assign numbers manually based on this info, which is silly. It would be nice in my opinion if they were in the table as long as the column header was labeled something appropriate given their haphazard industry adoption. What would be an appropriate header? How about 'non-standard numerical'? You are right when you say quite a few manufacturers use the same set. While not an official standard, it is still encyclopaedic i think.
