Other than the apparent offset between Sync-L and Sync-U, the K3 does
a pretty fair job of supporting AM TX and RX within the limits of the
6 Hz AM filter. The question is whether they should bother to support
wider AM ("Enhanced AM") to 4 KHz audio bandwidth as they do with ESSB.
I'm of the opinion that transmit audio bandwidth needs to remain
consistent with "communications quality" which is defined variously
as 2.7 or 3.0 KHz depending on whether the definition uses "highest
modulating frequency" or "necessary bandwidth". As an FCC official
famously said at the FCC Forum in Dayton, "If you guys what to play
with Hi-Fi, apply for a broadcast license."
The use of excessive bandwidth is not simply bad manners, it is against
the rules.

Not everyone sits on the edge of their chair and wants pinched audiosome like
to relax sit back and enjoy radio and a nice conversation.
I purchased the General coverage Bandpass filters because I also like tolisten
to SW, had they not been available I may have not purchased a K3.
I had a Flex, and while I did not like the interface, I did like the full sound
of the radio.
It makes sense for Elecraft to broaden their horizons (and market share),
