I downloaded the PDF and, as pointed out by N5RFX on QRZ.com, it appears that the ARRL is now proposing changes that would affect only 10 metres and higher frequencies, while everything below 28 mHz, including the newly expanded phone bands, would remain status quo.
I don't recall exactly how the "AM Exception" footnote was worded in the original document, but it seems to me to be a little more definitive in this one:
(5) The 3 kHz maximum bandwidth does not apply to double-sideband amplitude-modulated phone A3E emissions.
Do others interpret this the same way, or am I missing something?
